Consider using System Restore to revert to a previous restore point before making changes. A clean installation is safest by replacing the existing drive with a fresh SSD. Avoid modifying files in C:\Program Files, C:\Program Files (x86), or C:\Windows unless necessary.
@Gat Pelsinger Are you using a permanent license or signing in through a Microsoft account? If it's a permanent license, you might need to reinstall Office and then enter the license key. With a subscription, everything is managed online—just download the software and log in with your credentials. Once done, Office will be reactivated. If system restore fails as @Needfuldoer mentioned, consider using a blank USB and downloading the latest installer from Microsoft. A fresh installation will likely resolve all problems. As others suggested, create a clean image of your machine after setup—installing everything and setting up accounts. This way, if something breaks, you can restore from that clean state without redoing all the steps. After that, explore tools like the Windows Decrapifier script (though I’m not sure about the latest version for Windows 11, but it worked well for Windows 10). It can help remove unnecessary bloat, though Microsoft often includes new features in updates.
