I always move the taskbar to the right on any remotely wide setup that I have - including my 21:9 main. Had it at the top on my sp3. On my current portable (spectre 13.5) it's at the bottom, since I kind of have to use win11 due to the heterogeneous cpu arrangement (how "hard" could it be to port the scheduler to win10... yeah yeah we know), and while it annoys me when I dock it at work, the system (win11 pro, with MS account) absolutely does suck in a lot of other respects.

Right click latency in explorer is annoying.

Opening the settings "app" after first boot takes several seconds because who the hell knows - I personally blame it on moving everything to some thousand layers JS framework since I like being grumpy about that. This is a core part of the OS, FFS. Fairly certain that they have the talent to pull it off properly.

Search has been fine for me.

Language switching almost always breaks during updates - "ghost keyboard layouts" and such. Has been the case for a few years now.

General "we'll shove down whatever we feel like on you" BS.

Just let us pay for "ultimate" (a.k.a. end-user enterprise) and be rid of all the BS.

Getting WSA back (yes, I have the community version) and expanding on connected standby or however they call it now would've been neat, especially on a convertible, but it is what it is, I guess. WSL2 is also quite the improvement. Lots of other small little things like the task manager (not using procexp too often nowadays).
