Cannot open any audio controls.

Is Windows displaying the wrong time?

Did you go through the laborious updates after the repair install?

One thing I would do, if only to eliminate one possible cause, is to create a new Admin user and see if this user can access the controls involved. If it can then you would need to migrate your personal settings to the new user but as you have these issues I would personally start from scratch with this user, except for Data, and once all done delete the old user (an option is presented to save all files to the desktop which is always a good idea)

Try another scan first, if you like. Windows Defender Offline
Also try MalwareBytes free, not trial , version, link in my sig.

I just had an idea, try going to Advanced Startup Options, tapping F8 during boot up and click Last known good configuration (advanced) See if that might do it.

ctell88: It would be very helpful to know more about your machine - please update your system specs (use the easy system specs link in my sig)

You might also want to publish a Speccy report (file menu PUBLISH) and provide the link in a new post on this thread. The more information members know about your machine and software environment, the better they can determine a solution.

A quick search turned up a soultion by resetting the filetype association for .lnk
You might try the SevenForums default filetpye associations tutorial and scroll down to lnk - Shortcut link (lnk) files.
or directly download the reg file to restore lnk association here
lnk - Shortcut link (LNK) files.

This might get your control panel back in operation.

Thanks
