I mean, 10 minutes is pretty optimistic even for a relatively savy user. It took me somewhere around an hour to find and fix everything. On the other hand, it took me and a bunch of people on the Linux support subreddit around 20 hours of troubleshooting to get Linux into a mostly functional state on my PC, at which point I and everyone else had given up, so…
Its been nearly two years since then though, and given what a nightmare Windows 11 is, I guess I’ll have to give it another shot.
Thats assuming you already regularly install Windows, which most don’t. It should be the median install, by a normal user. In the same way, I wouldn’t count the experience of a veteran distro-hopper as the standard for setup time on Linux.
To find and quickly vet a cleanup script on Windows, I’d say half an hour to an hour is a fair estimate, esspecially given that there are a lot of fake or outdated ones out there. On top of that, there a bunch of other settings these scripts often ignore, like web search in start, so I’d say up to another half hour for that is reasonable, esspecially if you weren’t thorough when searching for your initial script.
