    Sony Windows 8 Refresh Caused Access Denied Error on C:\

    I am creating this post as I found no working solution using Google.

    First some background:

    I was working with a customer machine infected with the FBI (Money Pack) virus. The computer was a Sony AIO with Windows 8, UEFI, and GPT. I was unable to run any programs in normal mode. I was also unable to open safe mode. In addition, due to the GPT file system, I was unable to pull the hard drive and scan it in another system. Furthermore, the computer would not boot from Hirens and a Windows install disk caused it to lockup. I was able to run System Restore, but it failed before completing.

    Thus I tried the option labeled “System Refresh”.

    System Refresh completed fairly quickly without error, and upon competition the virus pop-up was gone. Also the user’s desktop icons were intact. I found however that I could not access their personal folders. When I clicked on C:\ I was given a simple “Access Denied” message. To make matters worse, I could run a cmd prompt, but not an administrator cmd prompt. Task Manager would not load as well.

    I did first try taking ownership of C:\ and resetting permissions but this made matters worse and I had to perform a second Refresh to undo that mess. The computer had only 1 user account and I could not verify the issue was related to the profile or not. Also, I could not create a new account as the Metro PC Settings menu was blocked as well.

    I found the solution in booting to Safe Mode (shift + restart) and first activating the hidden administrator account.

    Using the user account in Safe Mode, I could open an administrator cmd prompt.

    I then used “net user administrator /active:yes” to enable the hidden admin account.

    Next, logged out of the user account and logged in as admin while still in safe mode. Using the admin account I was then able to access Metro’s PC Settings and create a new user account.

    I then rebooted the computer and logged in as the new user. The new user account worked properly and did not suffer from the “access denied” errors.

    I then copied the user’s files from the profile on the C:\ drive to new account and deleted the broken account.

    In my experience the issue was simply a “corrupted profile” but due to Windows 8 the fix was much more difficult to perform.

    To recap

    1. Boot to Safe Mode using Shift + Restart
    2. Enable hidden Admin account using “net user administrator /active:yes”
    3. Create new user
    4. Copy files from broken account to new

    I hope this helps others, and is yet another proven reason why I hate Windows 8.

    The Access Denied may have just been a fluke in the initial installation. I just cleaned up one of these FBI viruses the other day, and was able to do a system restore with no problems.
