Take a look at the bottom portion of this Microsoft article:
http://support.microsoft.com/default...b;en-us;324767
What you need to do is copy Autoexec.nt and Config.nt from the
C:\Windows\Repair folder and paste them into your
C:\Windows\System32 folder. You then have to make both files Read
only.
Quoting from the article:
If the issue continues to occur, copy the Autoexec.nt and
Config.nt files from the Repair folder in Windows to the System
folder. To do so, follow these steps: 1. Click Start, click Run,
type c:\windows\repair, and then click OK.
2. Right-click autoexec.nt, and then click Copy.
3. Click Start, click Run, type c:\windows\system32, and
then click OK.
4. Right-click anywhere in that folder, and then click
Paste.
5. Right-click the Autoexect.nt file that you just copied,
and then click Properties.
6. Click to select Read-Only, and then click OK.
7. Repeat steps 1 through 6 to copy the Config.nt file.
Note You must enable Read-Only permissions or the files will be
removed after you restart Windows.
Post back if you run into any problems doing this.
