Huh, strange answers in this post. The top comment is just saying how nice and bug-free W11 is for their past few days of usage. That's...nice, but could be more constructive.

I'm gonna assume you're on W10, and not something earlier like 7/Vista/XP/ME.

If you actually are on an earlier version of windows, unless there's some reason, like say, a grandmother who'll throw a positively ballistic fit if you take away her XP, then you should upgrade solely for the updates alone.

For the majority of people on W10, there's not really any major reason to update. Aesthetics are slightly refreshed, some minor under-the-hood tweaks etc.

If you're getting new hardware, there's some advantages to running W11 with certain current-gen Intel CPUs, but it's not on the level of say, upgrading from an HDD to SSD for example. You definitely should get the latest version of OS for a new machine anyway, but most people thinking of upgrading probably aren't getting a new machine.

And if W10 works fine for you, there's honestly no real reason to update. Yes, it's definitely some once-off work if you like your right-click context menus back (and I do), and all the telemetry & hodge-podge menu design is still there. Still, once you fire up Chrome/Firefox/Office/Blender/any game/any program, you're probably gonna have the exact same experience whether on W10 or W11.

tl:dr No reason for W10 users, update please if you're on an earlier version of Windows, no reason to avoid W11 either.

If you have 12th gen intel cpu then definitely windows 11 for better cpu schedulers. Windows 10 won't help for 12thgen

If not no matter what you choose you cannot go wrong.

Windows 11 has fixed most of its bugs and is stable right about now and windows 10 is well windows 10 and since there are no major updates coming to it it's stable to.

Bascially if look past the unwanted hate it's all the same. Lot of people using 11 with absolutely no problem and 10 as well.
