I have a persistent problem with my windows 10 installation. Changes to the timeout setting make no difference. I have it set to 30 minues currently but whatever I have in the there, if I'm not interacting it times out after 10 minutes and locks.
I have also tried the following:
Registry values:
HKCU\Software\Microsoft\Windows\CurrentVersion\Lock Screen\SlideshowAutoLock is set to 0.
HKCU\Software\Microsoft\Windows\CurrentVersion\Lock Screen\Slideshowenabled is set to 0.
In Group policy:
Computer/Administrative Templates/System/Logon/"Allow users to select when a password is required when resuming from connected standby" is set to 1.
Local Security Policy:
Local Policies folder> Security Options> Interative logon: Machine inactivity limit is set to 599940.
