| Tool To Repair WindowsUpdates. |
| System resources, such as file data, registry data, and even in-memory data, can develop inconsistencies during the lifetime of the operating system. These inconsistencies may be caused by various hardware failures or by software issues. In some cases, these inconsistencies can affect the Windows Servicing Store, and they can cause a Windows Vista update to fail. When the update fails, it blocks the user from installing updates and service packs. Microsoft's CheckSUR addresses this issue. These updates contain the Check for System Update Readiness (CheckSUR) tool. CheckSUR will try to fix certain Windows Update installation failures. The following are the installation errors, CheckSUR van potentially address. These errors are typically listed in the %systemroot%\Logs\CBS\CBS.log file or in the CBS.persist.log file.

| Windows Vista Updates fail To Install. |
| If you find that a particular Windows Vista Update does not install, here are some suggestions: |
| First clear up your Temp File/Cache, Reboot and try again. Best and easier to use CCleaner. Disable your Firewall and try ! |
| In many cases, the update may fail to install in the first instance, but for some inexplicable reason, succeeds in the 2nd or 3rd try. So try a couple of times. |
| It it doesn't help, search on Microsoft, for the patch / update KB number, and download its Stand-alone Installer. Now apply the patch manually. Search for just the number; don't include KB ! |
| If it still doesn't help, try this : Rt Click Computer > Manage > Services > Stop the "Cryptographic Service" and rename the "Catroot2" folder situated in C:\Windows\System32\Catroot to something like say Catroot2X. Reboot. Now run the update/hotfix installers again. This action will re-generate a new Catroot2 folder and the updates/hotfixes, should hopefully install OK. |
| If still you have a problem then, go to C:\Windows\WindowsUpdate.log and look for the most recent entry. This will be present towards the end of the log. Any failed updates will have error code/s written next to them. Note them down. If you find just too many entries too confusing delete this WindowsUpdate.log and try installing the updates again. Now open the newly re-created WindowsUpdate log file and have a look at its contents.
The warnings will probably appear as -: WARNING: Failed to find updates with error code XXXXXXXX.
Now Rt-click Computer > Manage > Event Viewer > Applications and Service Logs > Microsoft > Windows > WindowsUpdateClient > Operational .
Check out for any Critical Message or Warning. |
Now refer the Windows Update Error Codes . This will give you the direction in which you may have to look for the solution. Or check out Microsofts Windows Update Solution Center. There is some nice info here too at UpdateXP some of which may find relevance to Vista.

| Cannot Update Windows using WindowsUpdate ? |
Broadly speaking, you can try one or more or all of these :
Run CCleaner to clear up PC Junk. Also flush the Software Distribution Folder.
Reboot. If you are using WindowsUpdate try using MicrosoftUpdates and vice versa. |
If you still cannot Update Windows Vista using WindowsUpdate, try this : |
| Open Internet Explorer > Tools >Internet Options > Security > Click 'trusted
sites' icon >Click Sites > uncheck 'require server verification'. |
Then add following sites :
http://*.windowsupdate.microsoft.com
http://*.windowsupdate.com
http://update.microsoft.com
http://update.microsoft.com/microsoftupdate/v6/default.aspx |
| Click Close > Apply > OK. This is known to help the GenuineValidated Windows, in some cases, but not always. |
| Do also ensure that you have the latest Windows Update Agent installed. |
| Try to re-register the following dll's individually.
See How to Register / Unregister dll's if you are not sure how to do it. |
wuapi.dll
wuaueng.dll
wups.dll
wups2.dll
wuwebv.dll
wucltux.dll
wudriver.dll |
| Alternatively, open Notepad. Copy-Paste the following command lines into it and save the file using a .bat or .cmd extension. |
regsvr32 /s wuapi.dll
regsvr32 /s wuaueng.dll
regsvr32 /s wups.dll
regsvr32 /s wups2.dll
regsvr32 /s wuwebv.dll
regsvr32 /s wucltux.dll
regsvr32 /s wudriver.dll |
| Double-click the icon of the .bat or .cmd file; command window will open. Run the commands, and then close. Reboot, and see if Windows Updates is working OK. |
| Also Open IE > Tools > Internet Options > Advanced > Security Settings > Ensure that the two boxes "Enable SSL 2" or "Enable SSL 3" are checked. |
| Hopefully, this should help ! |

If you are recovering from a malware attack, you may also want to have a look at your Hosts file. Some malware programs may modify the hosts file to control DNS name resolution. Remove ALL entries for Windows Update and Microsoft Update from your Hosts file situated at C\Windows\system32\drivers\etc\hosts |
| You can either remove any lines that contain entries for Windows Update or for Microsoft Update OR you can just place the number sign # before or in front of any line that contains "microsoft" and "update". HostsMan is a good freeware utility to help you manage your hosts file. |
| How To Download and Save Windows Vista Updates. |
| In Vista,Windows Updates is set to download only the files which need to be updated ! eg if xyz.dll needs to be updated, then only this particular file will get downloaded from the Microsoft servers. |
| But if you wish to, then here are two ways I know of where you can download and save Windows Updates for Vista. However the discussion is applicable for all versions of Windows. You only need to use the applicable Update List. |
Go to the Windows Update Catalog site and click on Find Updates. Here, you can do a full text search, using a keyword, KB article, MSRC bulletin, driver manufacturer, driver model, driver version, product, and a classification.
Select the Vista (or appropriate version of Windows). Search or click on Advanced Search if you want to refine your search. Click Add on the windows updates which you would like to save. Having done this, go to the Download Basket and mention the location where you' like to save them. Click on Download. If you have any problems, you can always refer the Microsoft Knowledge Base Article: How to download updates and drivers from the Windows Update Catalog |
| Or then, there's another way ! |
Download and Use Windows Updates Downloader. It is a small utility that allows you to DOWNLOAD & SAVE all of the current Windows updates. All updates are downloaded directly from microsoft.com to your computer with a single mouse click. But first you will need to download the applicable update list; and install it. You may download this list and the program file from here . Additional help is available at MSFN. |
| Update : The following script, based on this BlogsTechNet post, will re-register all the windows update dlls and recreate the software distribution & catroot folder. Download this Repair WU.rar file, it contains a bat file. Run it. You may wish to check it out. |
