I have a difficulty on updating my Windows 7 Ultimate SP1 through Windows Update!

• [updated] Windows Update ends up with different errors 80070008 or 8007000e , 80072EE2 , C80003F3, and 80244019.




• Windows Update Automated Troubleshooter reports (not fixed) :

  
  

  RootCause:
  RC_DataStore

  
  

  ErrorCode:

Other things that I have tried so far :

• Reboot (charger and battery removed)




• Updating system/windows date and time




• Checking Windows Update Options (Notify me when update available but do not download and install automatically)




• Windows Update is using the latest agent (Windows Update Agent 7.6.7600.320)




• System scanned for malware or virus - nothing found !




• Drive C got 109G and Drive D got 29G of free space !




• MY Windows copy is activated and genuine !




• [updated] Already signed up for Microsoft Update to get "Update for more products"




• [updated] I have checked Windows Update service in different times (seems no Windows server down)




• Internet connection is okay - connected through a Home network with no proxy (Direct Access) !




• I am using the system as the default Administrator !




• Microsoft Security Essentials is up-to-date and is the only antivirus software is currently runing on my system !




• [updated] System File Checker (sfc /scannow) found no missing or corrupted system files as Microsoft Support article kb/929833 suggested !




• I have recovered my system with my different systerm restore images to fix this but to no avail !




• [updated] Microsoft Fix it 50202 couldn't fix the problem !




• [updated] System Update Readiness tool (kb/947821) couldn't help too !




• After not getting result from above fixes, I reset Windows Update components manually as described by Microsoft Support - article kb/971058 - (even with aggressive mode - renaming SoftwareDistribution folder) but the problem still continues !

I really dont know what to do next ! Need your help ...

Error code 80072EE2 means ERROR_INTERNET_TIMEOUT, so also network related. The errors 8007000E and C80003F3 mean OUTOFMEMORY. There is an issue in Windows Update, that the service consumes a lot of memory during scanning for updates. Looks you run into the issue. Microsoft fixed that issue with the following update:

Installing and searching for updates is slow and high CPU usage occurs in Windows 7

So make sure it is installed., to reduce the memory usage and improve installation speed.
