Weird Windows 7 Registry Issue - HKEY_CLASSES_ROOT

gouletjo · 21 Mar 2010

I am using Windows 7 Home edition (x64 bits) and have noticed that there are no permissions set for HKEY_CLASSES_ROOT. The following message is displayed.

No permissions have been assigned for this object.

Warning: this is a potential security risk because anyone who can access this object can take ownership of it. The object's owner should assign permissions as soon as possible.

I can't installed Windows applications (using Microsoft installer) ranging Office, Midmanager and any other application.

Please I need your help, I bought this in January
Any advise
Thanks
Jonathan

When did this start?

I really don't know. I realized I had a problem when I tried to install MindManager. Each time I wanted to use the application I was forced to go over the initial setup. I googled my problem and was forced to realize that it was a registry issue.

Try this:

Found the following here: Post by qella3, near the bottom. Also simliar/same in a post by Arthur Xi here: WIndows 7: No Administrator Rights and C:\ is not accessible

Before doing anything, create a new System Restore point and/or a full registry backup using ERUNT

1) Download SubInAclat Microsoft Download Center SubInACL (SubInACL.exe) and install it. Default install is to C:\Program Files\Windows Resource Kits\Tools. You can change this to whatever you want.
2) Open a Command Prompt and navigate to the directory subinacl was installed in.

Type (or copy and paste) subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=administrators=f and press Enter.

That should reset HKEY_CLASSES_ROOT to it's normal value.

should I run this 2 line instead of just one
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=Administrators=f /grant=System=f /grant=Users=r /setowner=Administrators
subinacl /keyreg HKEY_CLASSES_ROOT /grant=Administrators=f /grant=System=f /grant=Users=r /setowner=Administrators

If I have to should I do it in a notepad file ? If it's yes how should I named the file ? Should I restored all my privileges (including HKEY_LOCAL_MACHINE and HKEY_CURRENT_USER directories)

Could this problem was initially initiated by TuneUp Utilities ?

thanks again

subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=Administrators=f /grant=System=f /grant=Users=r /setowner=Administrators

Is good. I will do the ROOT key and all subkeys.

Thanks ! If I need a beautiful toy to put on my table, I'd buy a Mac but I need a real computer. So, I own a PC.

I think I don't have an administrator account anymore. What should I do ?

What do you mean you don't have an Administrator Account anymore?

Built-in Administrator Account - Enable or Disable

Are you locked out of the Admin Account?
