I don't have an answer to this, other then my observation that many people who are in the debloat camp adhere to a no update mentality. I'm not knocking it but I do think its risky imoI'm not sure why you need to block Windows Updates, especially in Windows 10
Sysinternal's Autoruns provides a deep enough dive to show what's running. It gives me peace of mind of finding everything.Regarding startup items
I kind of like the idea of making sure none of the cruft is laying about. True that if you're not short on space its not impacting performance but keeping a tidy computer isn't a bad thing.Disk Cleanup will help you if you are super low on space,
I work fairly often in the registry for my job and I personally don't find the need to clean it. The inverse, in the early days of windows registry clean up utilities did more harm then good. With that said, I find uninstalling utilities that clean up all bits of an application including the registry is beneficial.- I think a lot of Mac faithful give the Windows Registry a worse name than deserved. It IS NOT newbie friendly and one should ALWAYS be careful of making changes there, but installing a program and then later uninstalling it isn't going to leave the kind of cruft likely to cause any sort of noticeable annoyance of any kind. This WAS the case in the Windows Vista and earlier days (and, to a lesser extent, in the Windows 7 era too). But it got a lot better in 8, 8.1, and especially Windows 10. Of course, this all depends on what you are installing or uninstalling.
