Default "sfc /scannow"

Hi there! I hope you can help me a little.

I'm using Vista Ultimate.
You can suppose that if I'm writing here it's because I'm finding some
problems (and I'm unable to solve them by myself).

I'm quite sure that I don't have malware on my computer. It's usually
not connected to internet.
I think I have some kind of system files & registry corruption.

"Chkdsk" says the filesystem is ok.
Next step would be running "sfc" (sfc /scannow). But it refuses to
start.
The message is: "Windows Resource Protection could not perform the
requested operation."
I already tried it starting in "safe mode".


I tried also to install "Service Pack 1" but it I couldn't.

What can I do now?

Did you run this from an elevated command prompt?

Thanks for your help.

Of course I did.
If I wouldn't do it, I would obtain the message:
"You must be an administrator running a console session in order touse
the sfc utility."

I already tried the command booting on "safe mode".

Any more ideas?

My apologies, I wasn't trying to condemn. Lots of people miss this one
little tidbit and it was not part of your post.

Maybe you could answer my sfc.exe problem while I continue to look about...
I run sfc /scannow (from an elevated prompt) and when it is done, it
states that it found corrupted files that it was unable to repair.
When I then look at the cbs.log using: findstr c:"[SR]"
%windir%\logs\cbs\cbs.log sfcdetails.txt, there are no errors in the log
file.

What corrupt files can it not fix?

Okay, back to your problem...
You've already done some of this. I'm just outlining the path of options:

1. From an elevated prompt, run the command: CHKDSK /F /R
You will be told the drive cannot be locked, would you like to perform
this on the next boot. Say yes.
This schedules chkdsk to run during the next boot before any other
windows operations lock up portions.
2. Have you tried the command prompt available from the Installation DVD
repair area?
This would skip loading your current system and give you a bit more
direct access. Note: Others with this problem have also run into your
message here.
3. Perform a system repair while you are on the DVD.
4. If sfc /scannow continues to falter, you can perform an inplace Vista
"upgrade" which would rewrite original files over existing ones and then see
if sfc works. (This will require you to re-install all updates, but don't do
this during the install.)

Hi Mark,
I used sfc.exe a lot recently when troubleshooting a crasy bug. I have never
seen an example where sfc does not say it found a bad file but could not
repair. And then when you do some searches in the log file you cannot find
one occurence of the words Microsoft documentation recommands to look at ie:
repair, could not repair, etc....
I have seen several posts on the subject here, including from guys who
installed Vista SP1, MS did not solve that one yet.
Cheers,

It does not repair ALL files in Vista.

The sfc /scannow command scans all protected system files and replaces
incorrect versions with correct Microsoft versions.

Default "sfc /scannow"

Thanks everybody for your help and comments.

In can tell more detais about this case:
-sfc doesn't even start scanning. I tried it on safe mode and also
booting from the Vista DVD (inside Windows Rescue Environment).
-The computer is stable. It can be used for the everyday tasks without
halting or showing errors.
-There's one difference from complete functioning: it refuses to
install some new programs. It's possible to install some of them but
not other. It's not possible to install Service Pack 1.
-I'm not sure but the failure can come from being shut down while
updating (after logging off and while showing the message "Don't turn
off the computer. Your computer is being updated").
-It's able to update some components from Windows Update, but other
ones fail every time.


I hope there's a better alternative than reinstalling completely the
operating system.

Thanks for the feedback. Never thought is was a major issue, but it seemed a
bit odd.

Regarding SP1 installation:
It will fail until all the required updates are installed first. So, the
major issue is getting all your updates installed.
Each failure is logged in the update history with specific error messages
which can be viewed by selecting the update.
A search for those error messages at MS may prove fruitful.

Additionally, you could clear the update log and force a reinstall of all
updates. (Better than a full re-install.)
Turn off the auto-update and install each manually in order. Clear any
problems before moving to the next.

The "problem" you're having is because you're not elevating the command
to Administrator level. To do this, start ALL PROGRAMS-ACCESSORIES-then
right-click command prompt and choose RUN AS ADMINISTRATOR. This will
open an elevatede command prompt where3 you type SFC /scannow (EXACTLY
as I've shown you) then just let it run and only touch the keyboard if
input is requested of you. It may (should) take only about 10 or 15
miniutes; if it takes more time then just let it go, when finished
you'll have a brand new startup (system install)
