This copy of Windows must be activated before you can log on
Every time you try to logon you get the following error message.
This copy of Windows must be activated with Microsoft before you can log on. Do you want to activate Windows now?
How to Resolve
Boot into "Safe Mode". To do this, turn the computer or laptop on and press F8 repeatedly as it is booting up. Go into "Safe Mode" by choosing the "Safe Mode" option.
Once you are at the desktop in "Safe Mode", Click "Start" then click "Run".
At the run command prompt type the following EXACTLY
rundll32.exe syssetup,SetupOobeBnk
*NOTE: The "Oo"'s in Oobe are "oh's" - not "zero's" There is one space after rundll32.exe. It is case sensitive as far as I know.
Click OK
Wait a few seconds - the screen may blip a few times or so.
This just reset Windows Activation for 30 days.
Got it working by logging into Safe Mode no networking (as local Admin) and then from a command Prompt:
rundll32.exe syssetup,SetupOobeBnk (and click OK)
(note: one space, after "rundll32.exe " also the Oo are two letter o's in "oobe"; capitals and comma are important)
- Delete LegitCheckControl.dll under C:\Windows\System32.
- Reboot
Was then able to run through the Activation without error.
