If MS stripped *ALL* ads and bloatware (telemetry for calc??) out of Win 11 and restored the traditional UI of start menu + desktop, it would be fairly good overall. Certainly within their top 5. They really are close to peak yet again but cannot realize they are striving to make it worse.
"A computer on every desktop and Windows on every computer" was the company's goal. Ever since they claimed success on that one (glossing over the ubiquity of Linux everywhere else) they've been sorta directionless.
