What is wrong with my .reg for screen saver?

Hi All,

Windows 11 25H2

Please resist the urge to give me GUI instructions. This needs to be a .reg. There is other stuff in it that I am not showing. Just the screen saver part.

This no longer work. It does not change the screen saver setting, even after a reboot. What am I doing wrong? What has changed?

REGEDIT4
; screen saver settings for 10 minute delay with a 5 minute grace period
; W11: YOU MUST be out of “settings” for this to take
; Does not require a reboot
; Note: ScreenSaveTimeOut is in seconds 600 sec = 10 minutes

[HKEY_CURRENT_USER\Control Panel\Desktop]
"ScreenSaveActive"="1"
"ScreenSaveTimeOut"="600"
"ScreenSaverIsSecure"="1"

; Note: ScreenSaverGracePeriod is also in seconds 0x12c = 300 seconds or 5 minutes
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
"ScreenSaverGracePeriod"=dword:0000012c

Many thanks,

-T

edit: I double checked the machines in question and they are set correct now. I have fast startup off. and I did a manual "shutdown /r /f /t 00" to restart. I think the user changed it on me. Thank you for looking at the issue. I think this is a no trouble found. Maybe it took two reboots?
