Joined Oct 18, Messages 5, Is anyone else getting the following error when attempting to download from Windows Update the latest update to Windows 8. I've researched the error and the only thing I've come up with relates to Windows 7 which, obviously, is not very helpful. I've also run the troubleshooter in Windows which claims to fix the problem So anyone else got this problem and found a solution?

Run a virus scan. Cookiegal Karen. Malware Specialist Coordinator. Joined Aug 27, Messages , Have you checked that you already have KB installed?
This needs to be installed before the large cumulative update KB which includes several other updates. Also,I see you ran the update troubleshooter but what did it report? I just installed this monster update with no problems. It hadn't been offered to me last Tuesday but just appeared pending installation for next Tuesday. I think that it may have been staggered for different regions due to the size of the update. I believe perhaps since it's such a large update that the servers were overloaded and possibly caused connection problems causing the update to become corrupt just my own theory so I decided to do the installation manually rather than wait for everyone to do it on Tuesday.
I have a couple of ideas for you to try provided you do already have update KB installed. Windows will create a new one when it doesn't find the existing one with the proper name. This should erase failed attempts to install this update so Windows Update should offer it again.
Note it will also erase your update history on the Windows Update site and start over logging from today however it will not affect the list of updates installed that you can access via Control Panel - Programs and Features. Reboot the computer. Open IE and visit windows Updates and check for updates to see if this update is offered again. If so, close all other Windows so nothing else is running in the background, put a check in the box and click on Install and let it download and install unhindered.
If there are other updates available do not select them for download at the same time. This thread is locked. You can follow the question or vote as helpful, but you cannot reply to this thread.
I have the same question 3. Report abuse. Details required :. Cancel Submit. Anil Kumar B. Hi, If you receive Windows Update error f8f while checking for updates, your computer's date and time might not be the same as the date and time for the online Windows Update service. I would suggest you to try these steps and check if it helps.
On the Date and Time tab, make sure that your computer's date and time are correct. If they're not, click Change date and time.
Boot-Loop on Windows Server On reddit. See also the links below. The error message is that the hypervisor is not running: Hypervisor launch failed; The operating systems boot loader failed with error 0xCBB.
This is probably update KB for Server R2 — just as a hint, if there should be problems under Windows Server — Many thanks for this. We were hours trying to resolve this as our HyperV virtual servers wouldn't start. Eventually came across your site, uninstalled update, rebooted and it now works fine. I wouldn't have worked this out to be honest if it wasn't for your site. Echoing this comment — same behavior, same fix.
Thank you very much for this thread! Rollback worked and I avoided a coronary episode. Thank you. Not sure if it's the solution, but I added the registry key below and the server hasn't rebooted for 40 minutes now. FYI — That key was introduced with a November patch for kerberos security. A later patch will enforce it and key won't do anything. But that was planned for the summer, hopefully MSFT has an actual fix by then.
I have 2 DC with r2, the updates did fail during install, so there is nothing to remove.. But still got loops. Need te restore them from backups.. I was desperately searching for hints this morning and couldn't find much until I stumbled upon your post. Thank you! One tip that helped me is that I could catch the DC before a reboot was triggered about 2 minutes after startup and then stop the Netlogon service. That stopped the rebooting such that I could troubleshoot and uninstall the update.
Thanks again! Dave, the net stop netlogon tip saved our bacon. Leave it to Microsoft to release a zero-day DC boot loop to their own customers.
We had similar issue this morning with Windows Server DC not R2 that kept going in reboot loop every few minutes of showing the signon screen of Windows.
It is a VM running on vmware. We booted the VM to safe mode by pressing F8 before Windows started and removed all last night updates and rebooted. Seems to have fixed the issue. We have changed the server to not install Windows updates automatically to avoid such issues in the future.
Does anyone have a comprehensive list of KB's for all server versions that are causing this issue? Blame all Server updates from R2 up to — see also the linked articles at the end of my text. Our W2k12 DC was updated on Wed, am. It did not reboot the hole day but restarted at night at about pm cause of the lsass issue, and about 20min after installing exchange 2k13 updates this evening.
We do have another unpatched W2K19 DC in a very a small enviroment.. The error message was that the hypervisor is not running. The moment you first logon. Immediately run command prompt, right click, run as administrator just incase 2.
