Temporary solution

user@host MINGW64 ~
$ rm -rf /c//python39//lib//site-packages/~ip*

user@host MINGW64 ~
$ pip list | grep pip
pip                       21.2.4

user@host MINGW64 ~
$ ls c:\\python39\\lib\\site-packages | grep ~ip

p.s. sudo is as temporary solution to #9527

There are a myriad of things can happen on Windows that make file deletion fail. We should add a message in the warning message to tell the user to delete those files manually.

@uranusjr , actually one can just create necessary folders. But i cant consider this as “reproducable approach”.
