I have installed 2018 on another computer recently -- a Core i7 also running Win 10. I have never used Defender on any computer, ever. Both these computers have McAfee Live Safe. With this second computer, I was also getting fresh boot starts of around 1 minute 10 seconds, though usually a few seconds less, but always over a minute.
On reading user experiences with Defender here and in another thread, I decided to fiddle around with it. So I enabled Defender, and updated it to the latest version of its virus signatures. I ran 2018 again, admittedly without rebooting, and still got times of 40 -- 45 seconds for these restarts, which is what I was getting before. So I deactivated Defender and reactivated McAfee.
That was yesterday. I closed down my computers overnight, and today tested PSP 2018 times after a fresh reboot of both computers. The i7 opened PSP to full usability in 40 seconds, with secondary starts taking 20 seconds. So something seems to have happened to make things considerably faster for me (though still slow compared to other users). I was inclined therefore to believe that updating Defender and rebooting may have been the cause, even though Defender remains disabled.
But I then booted up my i3 and the first boot of PSP 2018 took 45 seconds, and secondary restarts 25 seconds! In other words, very similar results again to the i7. Yet I had not touched Defender on the i3. Nor have there been any recent Win 10 updates -- the most recent was 31 January.
So yes, something has happened, but I am back to believing it was not Defender which improved things. The mystery continues!
