repair Vista installation ? anything like XP or 2000 available ?

Sorry Ranasrule, they've dropped Repair installation.

Vista repair options don't include XP's Repair Installation.

Try Check Disk
Start > All Programs > Acccessories
Right click command Prompt.
Select "Run as Administrator".

At the command prompt type
chkdsk /f  (there's a space before the /)
Press Enter.

Try Vista System File Checker:

Click Start » All Programs » Accessories.
Right click Command Prompt.
Select Run as Administrator.

At the command prompt type
sfc /scannow (dont miss the space before the /)
Click OK.

You may need your Vista DVD if prompted for SFC.

Another option.

Try System Restore:
Start > All Programs > Accessories > System Tools > System Restore
It's straightforward, but if you get lost, full instructions are here.
Using System Restore

Run System Restore from Safe Mode - it's more likely to work:

They've possibly dumped Repair Install because Windows PC Backup is now available, but not in Home versions.

I recommend Acronis True Image 10 to everyone who has Vista. Or XP for that matter. Very cheap compared to the problems it can solve.

Good luck,
Alan.

ok guys i tried what u suggested...no luck.....the problem is the WINDOWS UPDATE service simplky wont start....i cant start it manually either....in description it saus "<Failed to Read Description. Error Code: 2 > "....also when i try to start it manually i get the error message "WINDOWS could not start the windows update service on local computer ERROR 193: 0xc1"

hey Lee, is that not what i posted ?

Nobus, take a look at those pages; they're both part of the same website, but they are separate pages, and yours explains the Repair Options (Startup Repair, System Restore, etc.) but mine explains the repair in place by doing an upgrade install.

Hey Lee - sorry - you're quite right, takes a while to find it in the Faq

ok now the WINDOWS UPDATE SERVICE(wuauserv) is gone....its no longer even showing up in servics manager....any way to reinstall it ?iam using Vista Ultimate btw

anyone know how i can reinstall WINDOWS UPDATE SERVICE(wuauserv)  ?

First of all, I found no such file on my Vista system.  I then googled for wuauserv.exe and found various pages that said it was a trojan, like this one:

http://www.castlecops.com/o23list-773.html

I haven't yet found out the name of the Windows Update service, or how to reinstall it if it's gone.

From looking at the properties of the Windows Update service in SERVICES.MSC, I see that the "name" of the service is indeed wuauserv, but that doesn't appear to be the name of the file.  I found this page:

http://www.windowsitpro.com/Articles/ArticleID/15157/15157.html?Ad=1

where it said you could find the service names in a certain registry key (and I found it there under that name.)  What happens if you type from a command prompt:

net start wuauserv

"net start wuauserv" yields the following result

C:\Users\RAW>net start wuauserv
The service name is invalid.

Did you find wuauserv at the registry key specified in my link?

no sir....its not there :-(

This is beginning to sound more and more like a case of a repair reinstall (through upgrade, as given in the link I described earlier).

no way to simply reinstall the service ?

I haven't found any way yet...
