Disk Cleanup vs Updates
I needed additional free space on my desktop's 250G SSD so I ran Disk Cleanup yesterday. It eliminated 8G in WIN Update files that it said were on the drive but had already been installed (and which were no longer necessary to retain). Upon reboot all seemed fine other than it took a long time (2 hours) for the re-boot with the message "Reconfiguring Updates" (or something similar). All seemed fine thereafter.
I noticed that before the Disk Cleanup I had about 600 installed Updates. Afterwards I only had about 300. The dates of the 300 remaining updates spanned the period of time I owned the computer. This morning when I turned on my computer it noted that there were 2 Important Updates ready to be installed. When I checked them they were both dated back to 2015. I went ahead and installed them and all seems fine. I noticed on my second desktop (it's virtually identical to the on which I ran Disk Cleanup) that it did not have either of these 2 older updates (KB 3019978 & KB3075220).
Question becomes, what did Disk Cleanup do to "reconfigure the updates" that took so long, and am I going to get a bunch more prompts to install older updates in the days ahead?
PS . . . I posted this under the General Thread because it spans both the Update & Maintenance Threads and I did not want to double post.
