Windows 10 may be essentially an ex-operating system, but that doesn't mean Microsoft has relinquished its appetite for really ancient code. For proof, look no further than the icons contained within the antediluvian pifmgr.dll file that lives on in Windows 11 to this day.
According to this blog post on the Microsoft Dev site by Raymond Cheng, pifmgr.dll was added in Windows 95 and is chock full of icons that were created mostly for fun. The idea was that they provided a library of icons "for people to use for their own homemade shortcut files."
