On the first restart after the enable, it goes up to 100% then says that it cannot enable the feature and it's cancelling. On second restart, it says failure to configure the update and that it's reverting. Right now, I'm running DISM /RestoreHealth to see if I can find something in the log. My CBS.log is below. https://www.dropbox.com/s/hwesd9r3z23pvmb/CBS_before_DISM.log?dl=0 All the interesting stuff is between 21:17 and 21:23. You can clearly see that I tried to enable Hyper-V but I cannot see what made it fail. The DISM operation is complete, I'll restart my computer and then try to enable Hyper-V again to see if it worked. New CBS.log after the DISM. https://www.dropbox.com/s/e16cm4nyjqaalo1/CBS_after_DISM.log?dl=0 I have no idea of what is causing this to be honest. My Kaspersky Internet Security 2015 could be involved but I have no proof of it right now. Also, if you see something that I missed, let me know and I'll look for it. It'll be a good experience to find by myself.

You can do this by changing the value of the following. Found here. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network\MaxNumFilters A picture of the MaxNumFilters value is here. If it doesn't exist, create it. Set the data to 16 maybe since you already have 15. Then reboot and give it a go. Network Filter Drivers Issues in Windows 7

I know you don't want to uninstall Kaspersky but here's someone who did that to get it working. They had to do this along with changing the registry value. https://social.technet.microsoft.co...hypervclient-editionpackage?forum=w8itprovirt

Aura Sysnative Staff, Security Analyst Staff member Joined Mar 16, 2015 Posts 8,061 Jul 13, 2015 #9 It worked, thank you a lot Brian :) I was aware that Kaspersky could be the issue, but according to this thread it should have been fixed in the 2015 version (or one of the update). Cannot add hyper-v feature in Windows 8.1 with KAV 2015 - Kaspersky Lab Forum Hence why I didn't try it first hand. Now to see if reinstalling Kaspersky Internet Security will cause issues... I'll create a Restore Point first just in case. Anyhow, if you want, this thread can be moved to the general Windows Update section since it could come handy in the future.
