Just note that NTFS *does* have a limit on the number of entries in
the root directory of the drive.  Offhand, I don't recall what is the
limit [for some reason 127 is stuck in my head] but note that the
typical Windows installation has only about ~20 folders in C:\.

Subdirectories, however, effectively are unlimited.

A handful of extra folders in the drive root certainly will not cause
any problem, but just don't try to install lots of software to
separate folders directly under the drive root.

A number of common Unix utilities are available as native Windows
executables, so a POSIX environment like msys2 or mingw is not even
needed [unless you want it for some other purpose, 8-) ].

Also note that, on Windows, Powershell is able to launch programs much
faster than CMD.  [I don't know why, just that it does.]
