Systems don't really get slower over time because of used disk space. It used to be somewhat true when HDDs, and bad ones at that, were more common. Nowadays though what's left on your 2 TB <$70 2 GB/s SSD storage matters little so long as your drive isn't near completely out of space to the point it can't place things easily. Background apps/injections are another thing though. You can never uninstall an app for 10 years and your computer will be none the slower for it as long as you disable them from automatically starting up, loading 5 background services all the time, and having poorly written hooks into things like Explorer which constantly get loaded every time you open a file dialog.

Tinkering for tinkering's sake can definitely be fun though and there's nothing wrong with that. Sometimes poking at things, and sometimes breaking them, is a great way to learn new things or even just scratch a casual itch.

Yeah I kinda conflated two things there. One thing is that do I do poke at things a lot, I regularly run Sysinternals autoruns just out of curiosity -- which also "can potentially break windows" (what can't?), poke around in Process Explorer or even run Process Monitor occasionally to just filter out everything for which I know the reason, to see what else is going on. I remove stuff from context menus I don't want there, you name it. All those little things do add up, even if it just reduces the number of things I have to scroll past when doing other things. But I admit that I mostly enjoy doing it.

But while SSD changed everything obviously, in addition to daily partition-based backups I also make manual backups to my NAS with FreeFileSync, just so I don't have to restore full disks when I only want to pull a few files from the backup. While FFS is crazy fast checking for changed files, all those orphaned files are still not free... it's not about the size so much as about the number of files, doubly so when it goes over the network. I also rather often search my whole system for stuff, and there too, files and directories that don't exist are the quickest to search.

I wouldn't want to keep them around in the same way I wouldn't want to run a script that puts 100k tiny files with random content all over the place. Because it's just a pointless waste. And since I enjoy the process, I don't count the time I am using on that, so in my mind, I'm being frugal in a weird, misguided sort of way... I know I could spend the time to make more money and then just buy another HD, but I don't wanna :P
