Bug: Set as default file manager affects other user accounts

[Josh65-2201]

Description

When it set files as default other accounts are force to use files. Opening anything that uses file explorer just shows the "application not found" message with no promt to change it back like it does normaly. Disabling the default toggle effect all accounts also.

Steps To Reproduce

1. Create a second user account on Windows
2. Install Files and set as the default file manager on one of the accounts
3. Switch to the user account without Files
4. Try to open File Explorer and see error message

Requirements

• Option to set the default file manager should only apply to the current user account

Files Version

2.2.5.0

Windows Version

10.0.19043.1685

Relevant Assets/Logs

Account with toggle enabled
debug_fulltrust.log
debug.log

Account that should not be affected
debug_fulltrust.log
debug.log

Hi @Josh-65 could you try the following?

1. Start from a "clean state": Files not set as default on any account, explorer working
2. Turn on the toggle in Files on one account and close the app
3. Run "UnsetFilesAsDefault.reg" from the attached archive
4. Run "SetFilesAsDefault_HKCU.reg" from the attached archive
5. Check if Files is set as default only on one account

SetFilesAsDefault_HKCU.zip

Yep that work for settitng it on one account only.

Nice, lastly could you confirm that if you do the steps above:

• If you open Files, the toggle is turned on
• If you turn the toggle off, Files is correctly unset as default

Has this fix been added to the normal setting yet? Since I havent see a pull request or mention for it.

No, the above fix has not been integrated yet.
