Complete Guide: Backup Windows 10 for Fresh Install
Do you need to fresh install Windows 10 but do not want to lose all data? This article will show you how to backup Windows 10 for fresh install step by step.
Windows 10 fresh install is needed
If your computer has problems, such as running slow, system crashing, programs quitting randomly and the like, a fresh install may be the best way to fix it. It is hard to find the real reason behind your system problems, and reinstalling Windows can surely fix these deep-seated problems.
If you upgrade to Windows 10 from Windows 7 or Windows 8.1, you may find some system issues. After the upgrade, system may run slowly due to unknown programs taking up many computer resources, some programs abort in the middle of an operation, and other strange behaviors may arise. In that case, you can do a fresh install to fix all those problems.
How to keep the data stored on C: drive when reinstalling
Generally, after fresh Windows 10 installation, all your files and programs saved on C: drive will be lost. Getting rid of system problems is great, but having to reinstall all well-functional programs may be cumbersome.
Luckily, there are two ways to perform Windows 10 clean install without data loss. If your C: drive is large enough (at least 16GB of free space), you can reinstall Windows 10 on C: drive without formatting C: drive. In that way, Windows will move all data to Windows.old folder, and you can restore files from Windows.old folder after the fresh install.
You can also create a system backup, then selectively restore some of the files and programs to C: drive after the fresh install.
Backup your computer before clean install
If you want to clean system drive only and reinstall Windows 10, you can backup only system to avoid data loss. If you want to clean up the entire hard drive and start fresh install, you can backup the hard drive.
Considering the need to flexibly restore files from an image backup, you can use free backup and restore software AOMEI Backupper.
