If you can’t log into your computer because of a corrupt user profile, it can be very frustrating. Here are the steps to repair a corrupt user profile in Windows 10. According to Microsoft, your user profile can be corrupted if the antivirus program on your computer was busy scanning your computer when you were trying to log in to your user account.
Besides that, there can be many other reasons for a corrupt user profile in Windows 10. If your user profile is corrupt, you won’t be able to log in to your account. You can either log in with a different username (with administrator privileges) or you can boot your computer into safe mode and use one of the following methods.
Why does the user profile not appear in the registry?
This error is known to occur for one of the following reasons:
- The user profile is corrupt or missing: failed Windows updates or automatic Windows updates that include critical system file updates (including installing service packs) that update the user profile can cause this error.
- File system integrity compromised: The file system on the hard disk may be corrupted due to hard disk write errors, power failures, or virus attacks. In this case, the operating system cannot load the user profile to start correctly and the boot process stops.
