Is it OK to delete C :\ Windows Installer?

Hey there, I've been looking through my computer files and came across the 'C:\Windows Installer' folder. It's taking up quite a bit of space, and I'm wondering if it's SAFE to delete it. I've heard conflicting opinions on whether or not it's okay to remove this folder. Could you clarify for me? Is it truly okay to delete the 'C:\Windows Installer' folder, or could it cause problems with my computer's programs and operations?
