Bree, on your machines running Win10, did yesterday's updates seem to take up a bit more space than usual, for you?
After doing all my usual cleanup afterward (LCU/Restore points/Software Distribution...), it was still about 1.1GB.
I can't recall ever having one quiet that large.
I have more than enough room, but I like to keep it as lean as I possibly can. Just an OCD thing I suppose.
Yes, I have that same compulsion

In my case I'm obsessed with fitting all my backup images on the one 2TB drive (well two actually, the other is a backup copy).
Last night's updates/cleanups/backups were done in a bit of a rush (it was an eventful day, if you remember

). I didn't have time to compare the sizes with the previous month's images. Now you've asked I can't rest until I've looked....
...Back now
My best machine to compare any size change on would be my Win11 test machine, System Two below, running RTM Win11 22000. That has had no new software or user files added since last month's Patch Tuesday. The Macrium images are little changed, just over 100 MB larger this month over last. I always make my images immediate after updating/patching, in the belief that that's when it will be at its cleanest and leanest.
Mounting them and looking at System32 and WinSxS for the two Patch Tuesdays it looks much the same, the WinSxS component store is a little under 100MB larger now. LCU is of course empty.
I always start my cleanup with Disk Clean up (system files). I have learned to watch very carefully, some months you don't see Window Update Cleanup appear in the list. When that happens I always run DISM's StartComponentCleanup. I updated many machines last night, some on W10, some on W11, and some on W11 Insider builds. I remember needing to run DISM on some of them, but can't recall which those were.
As an aside, here's an interesting little bit of news. The 22621 Release Preview build (or Beta or Dev, come to that) no longer have any LCU folder. MS telemetry must have told them that the first thing we all do is delete it
