First startup after windows boot is extremely slow

[BK201]

It's crazy, for XnView MP 64 bits after first startup

Windows 10 Pro (20H2): no big duration

Windows 10 Pro (21H1), slow device: no duration greater than 0.09

Do you have an anti spam and/or anti virus app?

oh fuck

I add xnview folder to exception and cold start takes 0.5 seconds now

I never expected anti-virus app would mess with a harmless image viewer! None of other applications are affected by this!
Anyway, FINALLY, NO SLOW STARTUP ANYMORE!

One expects security software to check a new download, but it shouldn't be checking an application every time it is launched??

Could it be that changes in the 'MP filesize or some other parameter are being detected, maybe due to program configuration changes? A test for that possibility might be to launch, immediately close the program, then relaunch when nothing should have changed.

It's really weird indeed, xnview is the only app that was slowed by anti-virus I ever known, I don't know who is responsible for this, ms defender or xnview

Very speculatively, could it be that you have your settings and databases in Program (XnView) rather than User (System), and that changes in the program folder are being detected when the program is relaunched?

Yes, .ini and .db are in xnview folder
But there're many app store their .ini and .db in program folder too..

Always very speculatively, could it be that a rescan of XnView MP takes long enough to be noticeable, and that rescans of other apps if they occur are unnoticeable?

Do you all of you guys, who have this problem, have Windows Defender?
