Patch Tuesday isn't until next week. Yesterday, my start menu was the same as it has been since I configured it following the upgrade from Win 10 to Win 11 last year. Today it was different!
First, it only showed the first 2 rows of icons I had set and had "groups" of 4 (with pre-defined names) and the 4th (lower right) of each group opened to a larger selection of that group's genre. I didn't create them! My "Sherlock 7" icon was in "other" rather than "Entertainment". BTW - Sherlock 7 is a beta game by Kaser Software.
I finally saw that it was set on "less" in the upper right corner. I clicked there and it switched to "more" and showed my previous start menu including the 2 icons that didn't fit before (it's one row longer) and then those groups I saw under "less".
It suddenly appeared this morning AFTER I had to do a reboot to get CCleaner 7 to open properly. I changed nothing! What happened? Can I get the older form back? That's not critical because other than the 2 extra icons, it looks like it did before.
