    Cannot run any Admin programs, Access Denied on C:\

    Hi There

    I am trying to troubleshoot a windows 8 Sony Vaio laptop.
    I am not sure exactly what has happened but I cannot run anything on it.

    For example when I open My Computer and the C:\ I get "C:\ is not Accessible access denied"
    I can open cmd prompt but if I try to run as administrator I get and error saying cannot access.
    The same for any admin program, compmgmt, MMC, msconfig. but it says windows cannot access this file. I cant event run Task manager. and cant check event viewer or anything.

    I have tired a automatic repair, but it Diagnosis the PC but returns that it cant be repaired.
    I also tried Repair and the same occurs.
    I also tried give administrators ownership of the C:\ as it says "Unable to display current owner" but this will not allow ownership to change on pagefile.sys, hiberfil.sys and swapfile.sys. along with a mcafee install.

    I think it is the ownership error that is causing this but cant seem to solve

    Can anyone assist? I am pulling my hair out.

    I don't have a solution but I found a page with similar issues that may shed some light:

    Edit: By the way, it is noted on the utility that takes ownership via a Context Menu command, not to take ownership of C: in its entirety. You can do things like take ownership of C:\Program Files folder, if you are the only user on the system. But taking ownership of the entire C:\ partition causes problems.

I am getting access denied when attempting to get into a folder. Just recently installed Windows8. I had the same issue with win7, but I managed to resolve it. What do I need to do to get around this? I don't remember ever having had a problem with simply getting into one of my own folders.
