Group Policy to execute BCDEDIT

I need to execute the following command on all workstations:
"C:\Windows\system32>bcdedit /set {default} USEPLATFORMCLOCK on"

Can this be done via group policy?

Hi, got myself confused. (a) is solved.

I am unsure of where to start with (b)

Sorry, my post above was relevant to my original question before I edited it. It had two parts and the first I solved myself however the second remains as printed.

I thought of that but wondered if that would result in it being run every time at startup.

Ideally i only want it run once.

Oh, it takes less than a second to execute.
If you don't want to"wait", go like this

If exist %windir%\admin\bcdedit goto end
Md %windir%\admin\bcdedit
bcdedit /set {default} USEPLATFORMCLOCK on
:end

Open in new window

Thanks, I was not as much concerned with waiting as I was with potential side effects of running the same command multiple times. If it makes no difference to run it daily then the startup batch script will be fine.
