Okay , so this is what happened to me.
My regedit was disabled and I just had my PC formatted yesterday!

(Tip : Check if your regedit is disabled or not because if it is , it might create problems in future )
How to open regedit?

I use XP pro , so I can only give out steps for it..sorry.
( Start -> Run -> Type regedit and press enter. )
It should show a message saying , if it's disabled "Regedit is disabled by the administrator"

If it's disabled , here's how you can get it back.

1. Make sure your access to registry editing tools is setted to "Not Configured".
This is how you can do it.

Click Start -> Run -> gpedit.msc -> User Configuration -> Administrative Templates -> System -> Prevent access to registry editing tools -> Right Click Properties -> Set it to Not Configured. (If it's Not Configured already , then there's really no need to click Enable or Disable. Leave it as it is)

2. Then Click on Start -> Run. Type this command in Run box and press Ok.

REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableRegistryTools /t REG_DWORD /d 0

Copy and paste the whole or type it out , anything that suits you.

Then a prompt will come up with this question:
Value DisableRegistryTools exists, overwrite (Y/N)?
Type y or yes and press Enter.


This should get your regedit back , oh and don't forget to run a virus scan once you're done

Good post Fred, thats a good tip for the members who use XP to actually print off just in case they need to do that in the future.
And one of the things i do every night before i switch my laptop off, is to run ccleaner, registry cleaner, that keeps my registry free of rubbish and value's that shouldnt be there.

Yeah , I've heard about that registry cleaner thing before.
And thanks , I'm smart ain't I?
