If you’re trying to log into Windows 10 or Windows 11 and see the message “We can’t sign in to your account”, don’t panic. This is a common issue that usually means Windows has temporarily created a profile copy instead of loading your real account. In most cases, you can fix this without losing files.
Why This Happens
The error usually appears because Windows can’t properly load your user profile. Some common causes include:
-
Damaged or corrupted user profile.
-
Recent Windows updates.
-
Incorrectly shutting down the PC (power failure, forced restart).
-
Disk errors or corrupted system files.
-
Antivirus or third-party software blocking profile loading.
