Which rollup update to download???

MS is really beginning to upset me. I have to go to the update catalog because both of my desktops & my laptop will no longer find updates - they just set forever, searching for updates. All three of these computers had found, downloaded & installed updates(important ones only) up until recently. When I get to the update catalog, I am now presented with "security monthly quality rollup for windows embedded standard 7 for x64-based systems" or "security monthly quality rollup for windows 7 for x64-based systems".

Can someone enlighten me on what is the difference? Thanks

Hi,
You'd have to ask Microsoft
Or dive in through the rabbit hole of links for each KB
https://support.microsoft.com/en-us/kb/3205394
These are the only 2 that usually matter x64 for 64 bit and x86 for 32 bit

You don`t need embedded.

Do reply #2 from this thread, follow Mike`s instructions, it will fix your update issue.

Windows Update will not update and I've tried multiple fixes

You should not be installing what MS calls important updates until you read its description to see if you want/need it.

And set Windows Update like this.
