Dear Cygwin Team and Users,
since a few months I have issues deleting cygwin installations. In some cases
randomly the /usr/share/fonts/microsoft folder and the TTF files in it remain.
According to DOS dir the folder contains junctions to TTF files - not sure how
this is possible - afaik a junction is for folders. But what I get is this:
C:\ci\cygwin64_21081_16603\usr\share\fonts\microsoft>dir
Volume in drive C is SYSTEM
Volume Serial Number is 70C2-07FA

Interesting is that this does not happen always. I am working on a open source
project and our CI installs and removes cygwin about 100 times a day. I see this
issue about 20 times per month - distributed over all of our CI runners. Maybe
Windows gives the TTF file some special handling every now and again, but I
checked the registry and there is nothing pointing to this cygwin folder, except
the cygwin installation registry.
I couldn't find any method to remove these files. I made sure I have delete
rights and that nobody has a lock on these files, but still whatever I tried
(Explorer, cygwin admin console, DOS admin console, reboot a few times, chkdsk,
google) failed.
If you have an idea that could help me to delete these files reliably and/or
avoid this situation, it would help me a lot!
/usr/share/fonts/microsoft contains symlinks to TTF files:
$ ls -al /usr/share/fonts/microsoft/
total 158

What Cygwin symlinks look like to Windows tools depends on the filesystem, the
value of the CYGWIN environment variable, and other factors. See
