Thanks for the reply & information.
A year or so ago I did a clean install of Window 7 on a new SSD and had a lot of difficulties downloading and/or installing all the updates. I was downloading & installing them in chronological order & frequently restarting the PC. But it always seemed there was a critical update that was needed in order to proceed with further updates. I have pages & pages of notes on what I did. I was trying to avoid that time consuming nightmare. But of course don't want to create worse problems.
I took a quick look at the WSUS Offline Update that you mentioned & will go back over it again. Does it leave out any non-critical updates?
