10. Perform a clean or repair installation
A repair install or clean install will depend on how much data you wish to keep.

If you’re performing a clean install, you’ll be able to keep your personal files intact. To perform a clean install, follow these steps:
1. Download the ISO file for Windows 10. You can find the link here.
2. Burn the ISO onto a DVD or USB flash drive.
