It can be the legitimate Microsoft program related to Windows update, but it has been reported it can be malware also: www.auditmypc.com/process/wuauclt.asp

Things to do:
1. Right click>properties>version tab, and see what it says. Microsoft programs generally disclose details there.
2. Have the file checked by your antivirus program.
3. If you're sure you don't want it to run (even if it is legitimate): just rename it (if it's running in normal mode, do it in Safe mode).

Hope this helps.

scanning and version

may be the solution. unfort. when doing a nav scan on the entire prefetch folder the result is that no files have been scanned and nothing found. when doing the same to the file in the prefetch filder same happens. none of the files in the prefetch folder have a version tab. the one in the system32 does. is it safe to rename both files? what are they good for when i dont use the aut. update?

You can delete the copy in the prefetch folder. And (after scanning) you can rename the one in system32 and see what happens.

In reply to: prefetch folder?

When you launch software it takes time to fully load. Prefetching is XP's way of speeding up that process. It keeps a list of frequently and recently used files and programs and then creates prefetch files for them so that key components are loaded automatically along with Windows.

Now, there is no harm in deleting those files since they are not required for the software to run. In addition, if you still use the program(s) the files will be recreated later on. However, it is possible that that one file has become corrupt (it happened to me once before) so it may even be beneficial to delete them and let fresh ones be created.

When it comes to files in the System32 folder, I would not delete them. Instead, insert your Windows XP CD and then go Start->Run and type in sfc /scannow (with the space). That will scan all system files, including that one, and replace them if corrupt.

Hope this helps,
John

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
