Hello! I have a Windows 10 22H2 OS on a computer which is 9 years old, but working well (it is a high end computer). It has 128GB of disk space. 63.2GB of this space is used by a single hidden folder - C:\Windows\Installer, all of the space is taken up by multiple .msp (and a few .msi) files, which have been progressively building on my machine for the past 9 years. My question is simple - how do I get rid of the non-needed files from this directory, and why have they been accumulating.
