I just purchased a Dell with Windows 11 and don't like Win 11 so far. It has crashed on me twice. I do love the SSD drive for its speed, but I have heard long term reliability it questionable with the SSD drives. I keep most of my data on a cloud and I have a 2TB external HD for backups. I also use Office 365 and it won't allow me to place the various 365 shortcuts on the desktop. I'm considering doing a refresh and installing Win10.
As with many MS OS, the initial releases aren't that stable in all hardware.
There have been many Win11 Updates, some almost weekly.
Check for Updates and allow all the updates, it may improve your stability.
I've updated or rebuilt multiple Business AMD & Intel Systems, MacPro Intel BootCamp Native Boot & VM's, and Mac M1 using ARM version of Win11 within a Parallels VM.
Win11, The early versions were buggy, slow, cpu intensive... newer versions much cleaner. They improved the hardware drivers for GPU, On-board NVME SSD's, Card Readers, etc. These early drivers were hanging Win11 at times.
If you don't like the Win10/Win11 Tile "Start" Menu... for a few bucks you can get a "Win7 Menu" that is promptly supported with all the Win10/Win11 updates. Provides an improved "Feel" for those accustomed to Win7 & Older Menu systems. Much better and stable than free or open SW.
Start11 is for both Win10 & Win11.
Start11 restores the Classic Start Menu in Windows 11.

Good Luck, I was there with ya on initial release... I so disliked Win11. Now I find it even more stable than Win10.
