Q: Because the Windows installer folder is very large, should I delete things from it?

A:No! The C:WindowsInstaller folder is used by the OS and should never be changed directly.
If you want to remove applications, use the Control PanelPrograms and Features to uninstall them. It is also possible to run Disk Cleanup (cleanmgr.exe) in elevated mode to help free up space.
