Hi,
I'm having same or similar issue here.
Did anyone get to the root cause ot the problem here?
I'm using exec.Command to start external process. On Windows 10 and 11 it
runs quickly (under 1 second), but on Windows 7 (without SP1) it takes
about 9 seconds to start external exe or script. It is not issue with
external process since I tried it with different executables and bat
scripts and problem is always the same on the same machine, and there is
not problem on others.
