# Windows – can’t I change Window 7 registry key

windows 7windows-registry

I want to change a Windows 7 Registry key in HKEY_LOCAL_MACHINE->SOFTWARE->Classes->CLSID->B54F3741-5B07-11cf-A4B0-00AA004A55E8} -> InprocServer32. I ran regedit as administrator. But when I was trying to modify that key, it doesn't allow me to change and reports error as

Cannot edit: error writing the value's new contents


So why can't I change the registry key even in administrator mode? How to solve this problem in Windows 7? I also disabled my Anti-Virus but it didn't help.

• Because by default Administrators only have read permissions for that key

You can open the permissions window by right clicking on InprocServer32 and choosing Permissions....

Now to head off a XY Problem, why are you wanting to changes the value in the first place?
