How Microsoft managed to ruin the Start Menu, on the other hand, is amazing. I had to reinstall a computer because some Cortana corruption had made it impossible to launch apps from the Start Menu’s search results. Even though I disabled Cortana. Incredible.
My Windows 10 start menu lags. Press windows key or click on it, no response for a good ten seconds or more.
I have this on my work machine, a previous install, my home machine, a Surface Book, a remote desktop server on Windows 2016.
And yet, I've never seen anyone else talking about it. I can't believe I'm the only one who has this "my start menu has paged out to 5400rpm disk, then powered the disk down" experience.
I have too many computers at home, some verrry slow ones, and they all pop up the start menu within a second or two unless I've just booted the PC.
I work with a lot of people who use Windows 10 all day long, and I've never heard one of them ever complain about a slow start menu. Complaints about search results? Absolutely.
I suspect it's something you're installing, and I'm sure you'll deny that (and you very well could be right, I don't know) and these things are time consuming to diagnose, unfortunately.
A quick search yielded:
Maybe not the norm, but we're not the only ones. It's obviously an issue that exists.
Microsoft is actually uncoupling Cortana to Windows Search/Start Menu in the next major release, so this should be less of a problem.
