Recently when cygwin setup runs windows 10 started creating
"C:\cygwin64\%SystemDrive%\ProgramData\Microsoft\Windows\Caches" folder -
exactly like that, with %SystemDrive% not expanded, containing the following
files
cversions.2.db
{104937D1-3D41-4EB0-BE48-1725A96CC3A1}.2.ver0x0000000000000001.db
{42542F41-6950-48FC-BDFB-3961A7C4A653}.2.ver0x0000000000000001.db
{6AF0698E-D558-4F6E-9B3C-3716689AF493}.2.ver0x0000000000000001.db
{DDF571F2-BE98-426D-8288-1A9A39C3FDA2}.2.ver0x0000000000000001.db
{FAC7F33B-D66E-413B-9358-52C759023A9D}.2.ver0x0000000000000001.db
and logs a number of similar messages to application windows log from Property
System
Omitted duplicate property.

Turned out that the culprit is the /etc/postinstall/zp_man-db-update-index.dash
script which runs at the end of every setup session, although I couldn't figure
why: it just runs mandb with some fancy redirection and nothing untoward
happens when it is run manually and with admin privileges, but the folder in
question was never created until I ran mandb to create man index which for some
reason was not created automatically during installation, and when
/var/cache/man/index.db is removed which effectively disables this script this
folder is not created. I am baffled.
