Clean your “Windows Errors”… but not from an internet advert
Sometimes, even on websites that are trustworthy - but use heavy advertising to subsidise their existence, they promote so-called free tools that you can use to remove “Windows errors”. This is one such advert, that I came across this morning.

This particular one will not do any harm, however, it is an annoying lure. This, and ones similar to this, will ask you to download and install a tool, it will run and report that you have errors, BUT, it will not let you clean up the errors unless you’ve bought it.
The so called “errors” are not really a problem, they might have an affect of slowing down your computer - a small amount, but unless you are installing or removing software very regularly (daily or weekly) then the accumulative effect will be negligible and certainly not worth buying a tool, such as this, to resolve that small level of annoyance.
Warm regards to all
