Conflict between screensaver and screen timeout on W10

Question

Hello,
I was working on W10 with this configuration :
Screen timeout : 5 min
Standby time : never
It was working fine.
Then I wanted to activate a screen saver after 1 min inativity. It worked fine.
But then I wanted to lock session and ask for session password at screen saver exit.
After that, the screen saver do not work anymore, as well as the screen timeout.
I did not find any answer yet on Internet to solve this problem. I chekched with regedit but could not find any valuable information.
Can you help me ?

Answer 1

Try the screen saver password and timeout settings in Group Policy (gpedit.msc)

Also try increasing the time for both and see if it fixes the issue.

Answer 2

I do not have gpedit.msc on my W10 family edition.

Answer 3

I am convinced that it comes from an misconfiguration in registry.
If a log with another account on same computer, it works ok (with no session password at screen saver exit).
Perhaps I could compare both registry configurations, but I don't know how to do.
