I have two similar laptops, 840 g8 and 845 g8. The first is intel, the other amd.

The intel one had some kind of new touchpad, which doesn't work during the windows install. It was apparently some new thing introduced with intel's 11th gen, don't remember the specifics, but apparently other models had the same issue. Windows needs to connect to the internet to fetch drivers once installed, even 25h2 which I installed two weeks ago. Bonus points for the AMD ethernet dongle not being recognized, even though it's some random realtek, so I have to type my wifi password (my AP doesn't support wps). The AMD one works, even though the touchpads seem similar.

For a long time, the AMD's webcam didn't work. There's some USB doohickey that wasn't recognized (showed up with an exclamation point in device manager), and even installing all the drivers from HP's webpage didn't solve it. It solved itself somehow after some windows update two or three years later. Out of the box, it did have the webcam working, but the display brightness was somehow limited to "pretty dim". I was ready to write it off as just another crappy enterprise pc panel, but then I rebooted it into the bios and the thing burned a hole through my eyes. Installing windows manually fixed the backlight. Sleep on windows more often than not hangs for some reason, even now, 5 years in.

The intel had a long-standing issue with 4k output over its usb-c ports. At one point, installing the gpu driver from intel fixed it, but windows update would helpfully update it to an older, borken version. Nowadays we have 5k panels at work. I can only get 5k if the driver is initialized with the monitor connected. So if the screen goes to sleep, it won't run at 5k anymore when it wakes back up. Newer models don't seem to have this issue anymore.

Fortunately I'm only an occasional windows user, so don't care all that much. Everything worked perfectly under linux since day one, so apart from the comically bad display quality, I'm generally a happy camper.
