Windows 7 chkdsk not working

[meridius10]

I have a Toshiba laptop with W7 upgraded to SP1.

I noticed that it adds
autocheck autochk /r \??\C:
to the default
autocheck autochk *
in
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager in regedit.

Even if I modify it manually to autocheck autochk * it still adds autocheck autochk /r \??\C:

I don't think this is an administrator issue as my other laptop with W7 SP1 (SP1 included) does not have this problem.

Has anyone had this problem before and found a solution to it?

Anyone think running Chkdsk from the WinRE would help?

I was able to replace a TrustedInstalled file by running SFC offline, but the other version was not corrupted. The OP does have two computers and does have access to another autochk.exe file. But maybe running the chkdsk would repair the problem the OP has now.

Too late - I have already reinstalled, but thanks for your suggestion.

BTW - the laptop had its own recovery partition and even that had become corrupted. Luckily managed to find the recovery disks.
