Registry Editor, a main registry editing tool equipped in all versions and editions of Windows operating system, can be disabled, blocked and locked to prevent the RegEdit from been ran or executed by users in order to protect important system registry. Other possibility of Registry Editor been disabled is caused by virus or worm

Tip 2
Following tip is extremely helpful, and usually necessary in helping to rid your computer of a viral infection, which has disabled your registry access.  Many virus programs will intercept registry access, based on its original file name (regedit.exe), and prevent them from running.  The alternate copies of theis file will not encounter this problem.


Simply navigate to the C:\Windows and locate regedit.exe .


Once located rename regedit.exe to some other name (e.g. new_reg.exe) and double click the file to run.

Third Method:

STEP1. Disable as much as you can from your startup. Remove programs from your startup folder and such, so as not to lag down the bootup process. 

STEP2.Create a new shortcut on your desktop, point it to "C:\Windows\regedit.exe" 

STEP3.Log off, then log back on. 

STEP4.As soon as you see your desktop, double click on the shortcut. The system does not check for policies until a few seconds after it booted up. If you click on the icon fast enough, it should let you get in. After you close it though, it will not open unless you redo step 3 and 4.
