Please post here with your error code, so that the Community can try to help guide you appropriately.

ALL of my MS updates are failing. Both security and regular MS updates. It failed intermittently in the past, but now it is failing every time I run it, trying to install, failing and then pulling them out.; Is there nothing like Fix It for Win 8.1? I am going nuts with this. Yes, I went back to the last successful update (and the ones before it) trying to manually install subsequent updates to no avail.

The 8.1 update KB2919355 failed without an error code. Just the statement "We couldn't complete the updates, Undoing changes. Don't turn off your computer." This has happend numerous tikes in past 6 months. Also, if I choose not to automatically install updates, office apps don't work and system hangs. Please help ASAP

That would be good if they coincided. But the upgrade failures predate my Avast installation by many months.

I have a bunch of failed update packages Maybe your Avast uninstall didn't work completely. <eg> Check if they have a cleanup procedure? Most AV manufacturers seem to provide one on demand.

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