All my settings reset back to default on their own

[Haydar Dikmen5C9A]

When I turned on my pc today I realized all my Adobe apps went back to fresh instllation. All settings are reset. Recent documents are forgotten. Keyboard shortcuts forgotten. How do I fix this?

Do you have more than one user account on the computer?

When you say PC are you refering to a Windows system?

[Haydar Dikmen5C9A]

Yes, two use accounts, and Windows 10.

It sound like your user ID Photoshop Application data was lost so Photoshop setup Your User ID a new set of  user Application data for Photoshop containing Adobe defaults.   If you has a backup your system you may be able to recover your old photoshop user id application data from your backup.
