Refresh HKLM Key from Group Policy

[Guest]

Hi There,

I am wondering is there a way to refresh the HKLM registry key -
specifically this one -- HKEY_LOCAL_MACHINE\SOFTWARE\Policies -- without
logging off ? I have a software restriction in place disabling MSN
Messenger. I also have a reg file to enable it. But once enabled, the only
way for the software policy to NOT take place is to log off. Hitting the F5
key does nothing either.

I beleive that you have to reboot to refresh HKEY_LOCAL_MACHINE.

You can kill and restart explorer.exe to refresh HKEY_CURRENT_USER without
rebooting.

But you can try this anyway.

To kill explorer and restart it.

Open the Task Manager...
Ctrl + Shift + Escape | Click on the Processes tab | Locate and highlight
explorer.exe | Right click explorer.exe | Click End Process | Click
Yes to the Task Manager Warning that pops up | Click File on the Toolbar |
Click New Task (Run...) | Type in: explorer | Click OK

End Process on explorer.exe will make your Desktop, Taskbar and all programs
disappear. This can be startling. Restarting explorer will bring
everything back.

Try the GPUPDATE command.

Hi Colin,

This only works if you remove via the policy. I actually went into the
registry and changed the 0 to 1. So once I do that, I want to pull the
laptop off the domain and be able to run the required program.

You could try:

RUNDLL32.EXE user32.dll,UpdatePerUserSystemParameters

Though I'm not sure if this refreshes HKLM parameters.

Wesley - but if it is a Group Policy from the domain, then it would reside in
HKEY_LOCAL_MACHINE.

That post was in reply to...

RUNDLL32.EXE USER32.DLL,UpdatePerUserSystemParameters ,1 ,True

Refreshes HKEY_CURRENT_USER.

Not necessarily. Group Policies can also be in HKEY_CURRENT_USER.

Depends on the policy and if Computer Configuration or User Configuration.

Computer Configuration is usually HKEY_LOCAL_MACHINE.

User Configuration is usually HKEY_CURRENT_USER.

Some policies can be set in both.

This command only refreshes the HKEY_CURRENT_USER -

RUNDLL32.EXE USER32.DLL,UpdatePerUserSystemParameters ,1 ,True.

I need a way to do the HKLM which is a Computer Configuration policy.

Not that I am aware of. You might look at using user configuration SRP so
that it applies only to users that you want it to apply to and not every
user that logs onto a domain computer.
