Windows Installer Files bloating up my SSD space; how do you get rid of it?

[dogfishunlimited]

Spent some time today trying to delete files on my SSD storage (101 gb out of 117 gb) by deleting apps, and while it did a sizable number in freeing up space, I noticed that most of the remaining storage occupied was oddly enough, within the System and Reserved parts.

I did some digging on some articles, stumbling into this post which got me started on figuring out this problem, to which I downloaded TreeSize to figure out what was taking up so much space. In the end, I didn't have the same problem as that user, but I did find out that what was taking up most space was the Windows Installer files.

to which I found that most of the problem was with these .msp and .msi files taking up a exorbitant amount of space in here.

Does anyone know if there's a way to get rid of them? I've read enough that it's generally dangerous to try and manually delete them because you risk breaking something, so I will not dare touch the delete button here. I'm not very tech-savvy, I have the technical knowledge and slowness around computers like someone's 90 year old grandmother, so I would appreciate if some terms get dumbed down and explained simply, but thoroughly.
