Delete everything except windows 7. How to erase data beyond recovery. Preparing for resale


Many users quite often encounter a situation where they need to delete everything from their computer. This can happen for various reasons. Home, protecting your confidential data. For example, many people often need to sell a computer. Mostly, in order to obtain a new, more powerful model. You can, of course, sell a PC by unit, but we will consider the option when a person wants to sell the entire system unit.

We think it is clear to you that before selling your computer, you must remove all confidential information from it. It is advisable to do this, because valuable confidential information can be stored on the hard drive. For example, video materials, photos and other data that you do not want to leave to strangers.


Let us remind you that before you start using the hard drive, it is advisable to format it. During formatting, the entire disk is structured into clusters.


This process can be compared to breaking into cells. Each of the resulting clusters has its own individual address. It is stored at the beginning of the partition (FAT table). This table can be compared to a table of contents. While entering data, the clusters into which the information is entered are marked by the operating system as busy.


When a person deletes information, these clusters are recorded by the system as free. At the same time, the recorded data remains in them. Information in clusters will be stored until a person adds new information there. Therefore, returning deleted information is not particularly difficult. You don't even need to be a programmer to do this. This is done using special programs, for example, Recuva.


In order to remove information from clusters, you need to add new information in their place. But this is optional. You can simply do a full formatting of this disk. With quick formatting, your FAT table will simply be reset.


But, it should be noted that even complete formatting does not mean that the information is completely cleared. Special programs will help the Kulibins return some of this information.


What can you do if you need to delete data more thoroughly? There are special programs for this, like HDD Low Level Format Tool. Also, you can format it several times. Or better yet, invite a specialist (if the information is very valuable). But this is not our case, so we will do the formatting ourselves, using a systematic method.

How to delete everything from your computer? Let's do a full formatting.

To do this, left-click on the “Computer” shortcut. In the window that opens, select the desired disk, for example D. Right-click on it and click “Format”.





And this is tantamount to erasing the table of contents of the book. In this case, the chapters themselves will remain intact. Therefore, uncheck the box and carry out full formatting by clicking “Start”. During formatting, it is better not to overload the PC with any work, especially the disk being formatted. Formatting is complete. The system not only formatted the disk, but also checked it for bad sectors and repaired them.

How to delete everything from your computer The second formatting method

To do this, we need the Start menu command line. Enter “Create and format” there. We will have a file with the same name, click on it.



Select the desired disk, in our case D. Right-click on it and continue, as in the first method.


How to delete everything from your computer Formatting during system installation

During the system reinstallation, when you are in the disk selection window, click on the line at the bottom of the “Disk Settings” window.



Then, select the disk to format and click “Format”. In our case, because we want to delete all information from the computer, we will select each of the disks in turn.




We formatted all drives except the system drive (if we used methods 1 and 2). To complete the removal of all information, let's go into the system drive (usually drive C), and delete all folders except the Windows folder (it cannot be deleted, it contains our system). After that, don't forget to empty our trash.


Now you know how to delete everything from your computer. All that remains is to choose the method you like and completely format the computer. Many people prefer formatting during system reinstallation. Good luck!

The iPhone is one of the most popular gadgets today; the device is easy to sell for good money even after a year or two of careful use.

At the same time, the iPhone is a fairly personal device; over the course of its use, it accumulates gigabytes of confidential data and information that is undesirable to give into the wrong hands.

If the time has come to part with your favorite smartphone, you will have to quickly and efficiently delete all the contents.

Preparation

Here's what to remember before wiping your iPhone:

1. Backup

First, make a backup copy of your device. You can save a backup on your computer via iTunes or use the iCloud cloud service (if the size of the backup being created will fit in the cloud).

TO THE POINT:

You will need a backup copy if you want to transfer your data and settings to a new iPhone.

Even if you firmly decide to switch to Android, you will still need a backup copy, there are also photos, notes, contacts and other important data.

2. Apple ID

Check if you remember the login/password combination for your Apple ID account. If the smartphone was set up a long time ago or someone helped with it when purchasing it, you should remember the credentials.

To check, try logging into your account at appleid.apple.com.

TO THE POINT:

Only if you have a login and password will you be able to disconnect the device from your account. If this is not done, it will be very difficult to sell it, and if the data is erased, we will end up with a brick.

3. Jailbreak and unlocking

If the iPhone was purchased second-hand or in another country, it may be locked to a specific telecom operator. To work with any SIM cards in this case, the so-called Turbo-Sim is used.

This is a small board that is placed in the tray under the SIM card. Before resetting and flashing such iPhones, you need to study the issue in detail. A specific iPhone model may refuse to work with a specific Turbo-Sim model on a specific firmware version.

Without a clear understanding of the issue, it is better not to start the process; there is a possibility of getting a brick.

4. Apple Watch

If the iPhone you are selling is connected to an Apple Watch, you should unpair the two. This can be done using .

Deleting data

When you have sorted out your account, backup and made sure that the phone is not locked, you can start cleaning the device.

1. Disable the function Find iPhone (

2. Settings – Apple ID – Sign Out), you will need to enter your Apple ID password.

3. We erase all data ( Settings - General - Reset – Erase content and settings), you will need to enter an unlock code.

You can perform the procedure through iTunes on your computer.

1. Disable the function Find iPhone (Settings – Apple ID – iCloud – Find iPhone), you will need to enter your Apple ID password.

2. Sign out of your Apple ID account ( Settings – Apple ID – Sign Out), you will need to enter your Apple ID password.

3. We connect the iPhone to the computer and launch iTunes, in the section with the connected device, select Restore iPhone.

As a result, we get a clean iPhone without a single hint of personal data with the Apple ID disabled.

Don't forget to clean the outside

In order to now get the maximum possible amount for an iPhone, you should give it a marketable appearance.

Careful and careful users can wipe the iPhone with a cloth; others will need a little time to remove dirt, dust and debris.

TO THE POINT:

The main thing in this matter is not to overdo it. You can’t hide deep scratches and chips no matter how hard you try, but you can overdo it and cause additional damage to the device you are selling.

Now you can collect the kit and place an ad on the Flea Market.

Returning the device under warranty is a highly recommended measure when selling a used device. Secondly, what is the point of giving someone a chance to dig into your “dirty laundry”? And thirdly, an elementary rule of politeness - if a smartphone or tablet finds a new owner, the latter has the right to expect to receive a “clean” gadget, similar to the “out of the box” version.

In contact with

It doesn’t matter what you have in your hands, an iPhone, an iPod Touch player or an iPad tablet - the sequence of actions is the same for all iOS devices.

Attention! To avoid booting your iOS device in “eternal apple” mode, this method CANNOT be performed on a jailbroken device (Cydia icon on the home screen). Otherwise, only .

1. Open the application Settings and go to the section Basic, in which (at the very bottom) the menu item is located Reset, which is what we need.

2. Next, select “Erase content and settings” and in the pop-up window click Erase, if you agree that the data on the device will be permanently deleted, or option Make a copy then erase, if there are unsaved .

3. Enter the passcode and press the button “Erase iPhone (iPad, iPod)” in the pop-up menu that appears.

4. iOS is persistent and does not want to return to emptiness - another dialog box will appear asking you to confirm your actions&

5. For those cases when the function is activated "Find iPhone", an additional identification step will be required by entering a password for .

6. After pressing the button Erase put the device aside - the data deletion process will take a few minutes, after it is completed, the iPhone, iPad or iPod Touch will be reset to factory settings with all data deleted.

If your iPhone or iPad begins to slow down, freeze, “think for too long” and reboot for no reason, it’s time to delete everything unnecessary in the device’s memory. There is a high probability that the reason for such slow and unstable operation lies in the fact that the device’s memory is overloaded with content. Overload causes crashes, critical errors, and simply slows down applications. You can remove unnecessary things by hand, but this is time-consuming and ineffective.

To learn how to clear the memory of an iPhone or iPad by deleting all or only some unnecessary program files, read this article. We will also talk about resetting your iPhone to factory settings.

The settings of a mobile device or tablet store a lot of interesting information for the user. So, for example, in the “Main” menu there is a section “Statistics”. Open it and from there go to the “Storage” tab. It is in this tab that you can see how much space your content currently occupies in the iPhone’s memory. You can also see which apps are taking up the most space. Even the simplest mobile game can store megabytes of unnecessary information that is of no use and only takes up space.

For example, there was a case of an iPhone owner who was faced with a lack of memory. When updating the operating system of a mobile device via a wireless network, the iPhone entered Recovery Mode. This is the name for the condition when the device does not exit recovery mode. The owner of the mobile device did not want to lose all his content, so he did not want to restore it. As a result, he had no choice but to recover using the iTunes media player. But the information from the phone was not lost: the user restored it using iCloud. Many people don’t even know that backup copies of all data are stored on this Internet service.

In order not to encounter the same situation, it is necessary from time to time to clean the memory of your mobile device or tablet from information “garbage”, which quickly accumulates.

How to clean iPhone

There are six simple ways to help remove unnecessary information from your device's memory. In this case, you can delete everything, or you can only delete some applications and files.

Ways to clean iPhone from junk

  1. Restore an iPhone or tablet in iTunes.
  2. Erase unnecessary information and reset your mobile device.
  3. Delete iPhone settings in iCloud.
  4. Send a program from your desktop to the trash.
  5. Remove the program from the “Storage”.
  6. Uninstall a program using iTunes.
If you use one of the first three methods, you will get a clean operating system. That is, these three methods are radical; they completely “zero” the memory of a mobile phone or tablet. After the memory has been “cleared”, the mobile device must be restored again. Backups stored in iCloud and iTunes will help you in this matter.

Use the last three methods if you want to manually remove a separate program or its files. These are standard methods that allow you to partially get rid of information “garbage”, for example, unnecessary applications.

How to erase content and settings on iPhone

There are five steps to complete this procedure.

Step one: Go to “Settings -> General” and select the “Reset” tab.


Step two: Delete content and settings by selecting the appropriate option. Enter a lock password if necessary.


Step three: Here you need to confirm the request by double-clicking “Erase iPhone”. Double-clicking is used to ensure that you are absolutely sure of your actions, because they can lead to the loss of important information.


Step fourIf you have enabled the Find My iPhone feature in iCloud settings, enter your Apple ID account password. Otherwise, you will not be able to delete data from memory and reset your mobile device.


Step fiveAfter disabling activation lock, the display will go dark, and in the background of the Apple logo you will see the procedure for removing and resetting the mobile device. The duration of the process depends on the iPhone model and the amount of information being deleted from its memory. Typically, erasing data takes from 3 to 20 minutes.

When starting the procedure for deleting content and resetting settings, do not forget to charge your mobile device. Otherwise, you may need iTunes help.

Be careful! This information applies to owners of jailbroken mobile devices. When deleting content and resetting settings on such mobile devices, the Apple logo does not appear, but only an icon demonstrating the progress of the procedure. In this case, restoring iPhone is only possible using iTunes.

How to erase iPhone in iCloud

There is another simple way to completely erase all information from memory. All that is needed is an Internet connection.

Step one: Go to and turn on the “Find iPhone” function


Step two Find your device and select it.


Step three: In the upper right window, click “Erase iPhone.”


Step four “Erase” by confirming your request.


Step Five Enter your account password.


Step six: Press two buttons - “Next” and “Done” (without entering a message or phone number).


Step seven: Clicking the “Finish” button will start the process of deleting information.

If there is no Internet connection, the procedure will be performed as requested after the iPhone appears on the network.

Be careful! When you delete memory content, the Find My iPhone function will be disabled and the lock will be deactivated. In this case, the mobile device is activated without entering a password or the account itself.

For jailbreak owners! If your mobile device is locked to a specific telecom operator, you will need to activate it after the content removal procedure. This can be done using your operator's SIM card. As a last resort, you can use an adapter that will allow you to hardware unlock your mobile device. If, before cleaning, you used the method of unlocking a jailbroken iPhone using ultrasn0w, you will receive a completely locked mobile device.

This is how you can completely clear the memory of your mobile device using three simple methods. Now let's look at three other methods that allow you to delete information not completely, but partially - individual files or entire applications.

How to Delete an App and All Its Files from iPhone

Desktop, iTunes and settings will help you remove any application and all its files from the operating system memory.

The easiest way is to remove the program from the desktop. If you want to delete an installed game, touch its icon and hold your finger for 2-3 seconds.

If you downloaded programs from the Apple store, hover your finger and you will see a cross icon, and the application icon itself will “dance”.


Now everything is simple: click on the cross and confirm that you are deleting this application. Look in the screenshot at the red arrow that points to the cross that appears on the left side of the application icon when you hover over it.


Any application (program) can also be deleted using the “Storage” section. To do this you need to follow three simple steps.

Step one: Open “Settings -> General -> Storage & iCloud -> Storage -> Manage”.


Step twoTap your finger on the desired application. In the window that opens, you will see how much space this application, for example, a game, takes up in your device’s memory (documents and data).


Step three: Click delete and confirm. The process of deleting the program itself and all its files will begin.


It's not just apps that take up a lot of memory space. Memory is also “eaten up” by music and video content, contacts, notes, photographs. In addition to all this, the Safari mobile web browser also takes up a lot of space. This browser works similar to a computer browser. When a user visits sites, all of its contents are downloaded to a temporary storage folder. The cache serves to quickly open pages previously visited by the user in the future.

Data located in temporary storage helps pages open quickly and thereby saves traffic. But there is also another side to the coin. This data in the temporary folder takes up a lot of space and must be deleted periodically.

Each site allows a certain amount of data to be cached. You cannot influence this size in any way, for example, by reducing it.

This is especially true for active users who often visit websites or social networks. If you access the network only using your mobile device or tablet, you will constantly face insufficient memory. In this case, it is recommended to clear the temporary storage periodically. We will tell you how to do this in the next block.

Recommendation! To ensure that your mobile device works stably without freezing or rebooting for no reason, do not forget to get rid of the contents of temporary storage from time to time. This will help the mobile device to work stably and error-free, and the Safari web browser to load pages quickly. Periodically clearing the mobile browser cache makes surfing stable and convenient. Don't forget to clear your cache and you will avoid many problems.

How to Clear Safari Cache on iPhone

To do this, follow these six steps.
Step one: To get started, open “Settings -> Safari”.


Step twoDeleting all temporary files from the cache is done using the “Clear history and site data” tab. However, do not forget that data that can be used for tracking will also be deleted.


Step Three In this tab you will delete absolutely all saved data from all sites that you have ever visited. And to delete cached data from a separate resource, use the “Add-ons->Site Data” menu. Go to the tab where site information is stored and delete temporary files from there.


Step FourHere you will see all the sites you have visited and the data stored in the temporary folder of your mobile device. There is information about the general cache, and you can separately see how much memory is occupied by a particular resource you visited. If you want to delete information for individual sites, click “Edit” and then click on the red icon. Below in the screenshot there are two red arrows.


Step five: Having selected a site, confirm the deletion of all its data from the storage using the corresponding button. All information from the selected site will be completely deleted. The next time you visit, the server will have to re-upload them to temporary storage.


We looked at five ways to remove unnecessary information data from the memory of a mobile device. You can easily use one way or another. Just remember that the first three clear the content completely and reset the settings of the mobile device, and the last three allow you to delete a separate application (program) and all its files.

Over time, computer performance decreases. And this is primarily due to the “cluttering” of the operating system with temporary files, logs, etc. The best solution in this situation is to reinstall the OS. But what to do if it’s scary to do it yourself, or you simply don’t have enough time to configure the initial parameters and unpack the software? Read our article. She will tell you how to completely clean your computer without uninstalling Windows.

Types of computer cleaning

To solve this problem, you need to apply all known ways to increase PC performance. Completing only one of the steps does not guarantee successful resolution of the problem.

Removing junk using CCleaner

This software cleans up all the tails after uninstalling programs, surfing the Internet and deleting files. Therefore, for the initial cleaning stage, there is no better application. So do the following:

  1. Download CCleaner from this link if you don't have it.
  2. Install on your computer following the prompts of the Installation Wizard.
  3. Open the application and go to the “Cleaning” tab – “Windows”.

  4. In the list that appears, check the box next to the fields you want to run.

    Attention! Deleting temporary files, emptying the trash, etc. it is impossible to cancel. Data will be lost forever!

  5. Next, go to the “Applications” tab and also activate the required fields. This module does an excellent job of clearing cache, cookies and browser history.


    Attention! Pay attention to the “Saved Passwords” item. When activated, all login data for sites will be deleted. Create a backup copy or uncheck the box.

  6. Now all that remains is to press the “Clear” key, confirm the action and wait for the operation to complete.

  7. After completing this module, go to the "Registry" tab. Here, all parameters are selected by default; it is not recommended to edit them.
  8. Now click “Search for problems”, and after scanning, click “Fix”.

  9. In a new window, refuse to create a backup copy.


Freeing up RAM

The fullness of RAM is one of the most important factors. There are no short instructions for cleaning it; the issue must be approached with all seriousness. Therefore, we recommend that you read the article: “”

Defragmenting your hard drive

This measure not only increases the performance of the system, but also extends the life of the equipment. Users copy, move, and delete files all the time. This leaves a serious imprint on the functioning of the hard drive.

The fact is that during the above manipulations with the object, data is written to free memory cells. If the file is too large and does not fit in a certain area, it is divided (fragmented) and recorded in different areas of the HDD. This, in turn, increases the hard drive’s response time to provide information and causes stuttering.

Attention! This operation will completely delete all data. Back up your important files. Do not format the system partition!

I will end here. Now you know how to completely clean your computer without uninstalling Windows. Be careful with formatting and keep your computer software clean. Good luck!
