I have had that machine for a while and would have the Win Expl. issue constantly until recently.,
update:
argh.... that 2022 machine just did it. PROBLEM STILL EXISTS
===
I went back to my 2023 machine, used Excel for about 15-minutes with Win Expl. window open in the background, no issue.
summary: no clue ... both have the same Windows definition and OS build, both have Bitdefender running (both updated today and had both machines rebooted this morning). Both machines are similar (Intel i7 but different generations), both have the same DRAM (but the 2023 does have a dedicated graphic card) .... but that would not explain why the 2023 DID have the Win. Explor. issue until recently, so I would not suspect the hardware unless there was a security update to hardware.
