How to Reinstall Windows 10 Without Losing Data (2 Quick Ways)

There are two ways to reinstall Windows 10 quickly. Both the features are built into the system, so there is no need to use third-party software.

Fix 1. Using "Reset this PC"

Step 1: Click on the Start button, and then click on the Settings icon. Navigate to the Update & Security settings and locate the Recovery section.

Step 2: In the recovery section, you have two options—Reset this PC and Advanced start-up. Click on the Get start button under Reset this PC.

Step 3:  In the Reset Wizard, you will get two options—Keep my Files and Remove everything—choose the former. You will be asked if you want to download and install Windows or Reinstall from this device on the next screen. Choose the latter and follow the wizard to reinstall Windows.

While Reset this PC works without a problem and saves your files, however, it will uninstall apps, programs, and drivers. Installing everything will take a lot of time. It is better to use software such as EaseUS Todo PCTrans, which can take backups and restore them.

You can use two scenarios:

Backup Files

The software offers a dedicated section of Backup and Restore where you can choose to backup only files. While the defaults are automatically selected, you can edit and choose the files you want to include. The backup is saved into an external drive. You can backup all the programs, settings and data for free.

Once the upgrade is complete, and if you notice a loss of files, you can always restore the method to bring back the lost files. You can choose to restore fully or partially by selecting the files from the backup.

The backup files can only be viewed through the EaseUS Todo PCTrans software so it is safe from everyone else. 

Backup and Restore Programs

The exact section also offers taking backup of Applications, User Accounts, and Files. The most significant advantage of using this method is that it saves a lot of time, and you don't need to pay for it. You will not have to reinstall applications from scratch. You will not even have to activate them again using the keys when you restore applications. It will carry over all the settings, customization, and activation status to the upgraded OS.

Step 1. Create a backup image of installed apps

1. Launch EaseUS Todo PCTrans on your PC and go to "Backup & Restore", click "Start" to continue.

2. Select "Data Backup" on the Backup Method window and click "Next" to continue.

5. Last, click "Back up" to start creating the backup image of selected applications. When the process to completes, continue with Step 2.

Step 2. Restore apps from the created backup file

Note: If the app exists on your PC, it won't restore the app image to your PC. You'll need to uninstall the existing one and retry again with the next guidelines.

1. Plugin the hard drive that create the backup file and open the PCTransImage folder. 

Double-click the file you backup and it will automatically turn to the EaseUS Todo PCTrans interface.

2. On the Application section, tick programs and applications that you want to restore from the image file and click "Restore".

The method to backup files and apps are similar, and all you need to do is make the selections correctly. Once you launch the application go to Backup & Restore, and then choose Data Backup before upgrading. Select apps and files and done. Once Windows is upgraded, you can then use the Data Restore method.

During Restore, you can choose to restore everything or only a few things. The migration settings also allow you to skip system files and folders and perform in case of a duplicate file.


It is essential to take a backup before an upgrade. It can be your files or applications, or both. Windows Upgrade Process takes care of backing up personal files, but it doesn't take backup of applications. So if anything goes wrong, you will end up reinstalling everything. 

This is why it is important to use professional software such as EaseUS Todo PCTrans offers more flexibility and assurance of data being intact. The backup method is secure, you can restore quickly, the file integrity is maintained, and so on.
