Hi My PC has tried to install update KB3048778 on some 6 occassions... each time failing and undoing the changes on restart. I hasve checked that I have no removable media in drives but it makes no difference. I have Norton 360 installed- is that likely to be the problem? Thanks MIke

I have error codes 80246013, 80246007, 800F0841 and 80070643. Can anyone identify the problem for me and a fix?

I get the 'Couldn't complete DL. Undoing changes' message. I followed the instructions above and found these failed updates: From a month ago: KB3024755 KB3025417 KB3036562 KB3012702 KB3012235 From today: KB2972094 KB2966804 Any guidence to fix this is super appreciated.

We've had this "undoing changes" error several times over the last couple of months and I am at my wits' end. The latest error code was for update KB2976978 with error 800F0922. Please can you advise how we can fix this once and for all as it seems that every update we install gets an error now.

I am having the same problem. The error code is 800F0922

Error: We couldn’t complete the updates, Undoing changes. Don’t turn off your computer.
