Why do Windows based PCs and Laptops appear to ‘degrade’ over time, appearing to run slower than when first purchased even after fresh Windows installations?

Lots of variables I accept 《edited to remove personal view》

After say, five years, their performance is noticeably slower than it was when they were new, and the question is not in reference to increased graphical demands from games. The question is referring to day to day operations, web browsing and so on. Moving parts are limited, could they be the cause?

Thanks in advance

Windows has a really poor handling of software installation/update. Basically, it’s up to the software to do 95% of the job.

For example, most software will share some common “redistribuable” if they are already there. But Windows don’t provide a way to know who is still using what, so most software simply don’t uninstall those when they upgrade themselves or when they get uninstalled.

Additionally, a lot of software need some “always on” service. They all do the same thing, typically, check for update, pre-load the app for faster start, receive any associated file access request. But those service start with Windows and run continuously, taking a little bit of compute cycles.

Full disks are slower, especially with SSD. Data need to be relocated when it grows, files stop being continuous.

All those things add up, and the system become more and more busy all the time. Doing a full reinstallation get rid of all this.

Most hardware doesn’t really get slower with age. It may heat a little bit more and consume a little bit more energy, but usually there is room before reaching thermal throttling, and before that is reached, it doesn’t really slow anything down. So that isn’t the main culprit, unless you toy with overclocking.
