Hi,

Thanks for posting in Q&A platform.

The size of the C:\Windows\Installer folder is by design and it is not supported to delete files from it. So, the question usually asked is: Can I safely remove the files in this directory? The answer is flatly: No.

The proper way to alleviate space pressure in this directory is to uninstall any unneeded applications. Or some third party tools may help you resolve this issue, please refer to the following similar threads discussed before:

No, don't delete it. Disk Cleanup should sort it.
