Apparently, this will randomly happen between patch-Tuesdays. The same bug that existed in 22H2, still exists, lol.
I had that problem, before the update, hours ago, lol.
I was working on an Acer Nitro 5 that my sister purchased during the early-2020s, IIRC. It has a 9th gen Core i5.
Everything is fine, except for no KEK. I can't get the KEK, looks like I'm cooked.
That's exactly what happened with the majority of the summer, 2025 updates. There would also be hundreds of files reported to be missing by CBS.
This made me wonder if Windows auto disk cleanup was causing the issue.
The WinRE issue is back:

Unfortunately, the 23H2-like event ID 4502 is back, the one where WinRE servicing failed.
Looks like we have to make the WinRE partition bigger, again!
