After installing Windows 10 on my laptop, I noticed that the C:\Windows\Installer folder has now reached 23.8 GB.  Since I only have a 128 GB SSD, the size is getting ridiculous. It’s not nearly so large on other Windows installations I’ve checked.  

My question is: can I clean this somehow?

Some preemptive notes:

1. I have already done all disk cleanup procedures, including system files and old windows installs
2. The folder is already compressed
3. I gather from other forum posts that programs like msizap and cclean don’t work
4. Some of the msi/msp files are super old: like 2008, whereas I bought the laptop in 2013.

Worked for me
