Method 3: Clean install Windows 10/11 without losing data
If you prefer installing Windows 10 without losing data from USB drive or installation disc, you can choose to upgrade Windows 10 using this method. Before you do, you need to make sure your C: drive has more than 16GB of free space.

After copy all your needed files out from Windows.old folder, you can use Disk Cleanup to delete the Windows.old folder to free up disk space.
Reinstalling Windows 10/11 isn't always a perfect solution
Though there are several methods to choose, they all have some shortcomings in practical use. For example, the first method will keep your programs, but won't fix problems caused by them. And the other two methods can only keep your files, so you have to spend time and effort reinstalling these apps. That's why I say reinstallation is not a perfect way.
To avoid such trouble, you can use a free backup software to create a system image in case of possible system issues. For simplicity and effectiveness, I strongly recommend you AOMEI Backupper Standard to protect your Windows 10/11 PC.
- It enables you to backup file, partition, system or even the whole disk in a simple manner.
- It can save you from manual operation with the scheduled backup on daily, weekly, monthly, etc.
- With the incremental/differential backup mode, it will only backup changed files instead of all files, which greatly reduces the risk of the backup disk full issues.
- You can change the compression level, split backup images, use Microsoft VSS service and intelligent sector backup as you like.
Download this software to create a backup image right now with the following steps.

Then, let's get the detailed steps.
1. Launch this free backup software, click the "Backup" tab on the main page, and then choose "System Backup".
Note: If you want to backup entire disk, you can choose "Disk Backup" as instead.
2. Select a destination location to receive the backup image. You can backup to any location (folder) that Windows detects, including external hard drive, NAS network location, local storage, etc.
3. In the next screen, click "Schedule" to configure scheduled backup settings if needed. After that, click "Start Backup" to start the operation.
Note: System backup in AOMEI Backupper Standard can satisfy almost users' need. But if you have advanced needs like below, higher editions like Professional may serve you better.

• Scheme: This is an indispensable feature for all users who don't want to miss any changes, but worry about disk space issue. It can delete old backups automatically when backup versions reach the specified number.
In a short time, the backup will be created. With a backup, whenever you have problems with your system, you can easily restore from the backup. Even when your PC fails to boot, you can restore from bootable CD. AOMEI Backupper also enables you to create a specialized recovery environment for backup/restore without booting Windows.
