Cleaning the Windows\Installer folder

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:

- I have already done all disk cleanup procedures, including system files and old windows installs

- The folder is already compressed

- I gather from other forum posts that programs like msizap and cclean don't work

- Some of the msi/msp files are super old: like 2008, whereas I bought the laptop in 2013.

Thanks for your help!

Hi,

Thank you for posting your query in Microsoft Community.

The Windows Installer Cache, located in c:\windows\installer folder, is used to store important files for applications installed using the Windows Installer technology and should not be deleted.

The installer cache is used to maintain (remove / update) the applications and patches installed on the machine. The installer files are a record of file versions and registry dependencies involved in a particular application or application update installation. The availability of this record in the cache helps to uninstall and update applications properly.
