Yesterday we started receiving an unprecedented rush of computers all showing exactly the same symptoms…
The symptoms are all described as follows:
Windows 7 gets stuck at the starting windows screen…
Once you decide to reboot the computer you will be presented with the following boot up screen…
When you choose ‘Launch Startup Repair’ you will be presented with…
The error shown is either 0xC000000e or 0xC000000f and in both cases we have attempted a repair of Windows, CHKDSK manually via a Startup Repair, partition repair and volume scans. All of which fail to repair the system.
We have also attempted to perform a System Restore but all system restore points fail.
At this time we have no update as to how to solve this issue other than a complete wipe & reinstall (factory reset) of the computer. PLEASE MAKE SURE YOU HAVE A WORKING BACKUP BEFORE YOU PERFORM THIS OPERATION.
We have raised this issue direct with Microsoft and are awaiting their feedback.
UPDATE: 12:16pm GMT: We have discovered that this issue has been caused by an update of AVG yesterday and is NOT related to Microsoft Updates. The advice is DON’T restart your computer until a later update has been released by AVG (we’ll let you know when). We found that it was AVG update 9542 and 9543 that has been breaking the machines..
The fix: Start up the computer in SAFE mode disable all AVG services or uninstall AVG. If that fails, download AVG Recovery CD and boot with the CD. Uninstall AVG using the recover DVD.
Update: 15:54pm GMT: We have just tested the latest updates and they are still causing issues with Windows 7. We recommend that you leave your computer switched on over the weekend which will allow AVG to automatically update itself.
Update: 22 June 09:20am GMT: It appears that only computers with Trusteer Endpoint Protection AND AVG are experiencing the problem. Uninstalling the Trusteer program solves the problem.
Update: 29 June 17:17pm GMT: We have spoken to an AVG support agent today and been told that they anticipate a fix by the end of this week or early next week.
