Windows installer made a copy of the msi, just in case it was needed later and put it into C:\Windows\Installer. It kept it even for packages, that were uninstalled or superseded.

On my Win10 system, that directory is ~600mb, ~300 files and 17 directories. Not advocating for this system, I just don't think it's that much of a problem.

  I have a Win8.1 system, where it is 40 GB. That crossed the annoyance line some time ago.

I never remember having seen such folder. Having been doing Windows development since Windows 3.0. I have been hit by such errors, which on my case were caused by .exe installers.

  It is hidden+system, owned by builtin\Administrators and competes with WinSxS, who will take most of your diskspace.

    I stand corrected. All those years without noticing it. :\
