MS Solution in kb811805 not working

Hello!

I have 2 problems. My first problem is precisely the one described in Troubleshoot failures in detecting new Bluetooth mouse or keyboard. My second problem is to
implement the suggested solution.

I simply can't delete the indicated registry entries because Regedit
doesn't allow me to change their permissions. When I try to take
ownership, I face messages like

"The registry editor couldn't change the proprietary in the key currently selected or some of its subkeys"

(or something like that. I translated it from Portuguese.)

In fact, I can't even read the content of some subkeys.

I am administrator and single user on my personal laptop.

Any ideas?

Thanks.

The problem is, you are *not* actually an administrator - you run with a split user permissions token, and have the same rights as a regular user by default. The default Administrator account is disabled with no password by default on a Windows 7 machine, and it probably makes sense to enable this account, give it a password, and log in with this account to resolve the issue because it is not subject to some of the token restrictions other administrative accoutns are subject to when UAC is enabled. Once you're sure the problem is fixed, disable the Administrator account again for security reasons.

Oops...
I haven't tried that...

Anyway, my system was getting worse every logon. In the registry I had lots of null entries
in these key groups the solution mentions. As this seemed not to be my only problem, I
ended reinstalling the OS.

It seems ok now but I guess I won't know if the problem was my user permissions or null
(perhaps corrupted) entries on the registry.

Cheers!

PS: are you familiar with linux? I would like to know if this level of rights windows gives
me as administrator user is the equivalent of a regular "sudoer"...

Think of "Run as Administrator" in Windows 7 the same as getting sudo permissions in Linux.
