Your explorer issue is Windows Defender's realtime protection. If you toggle it off you'll see the operation you're trying to run complete almost instantly.
I like Windows 10 and generally have been happy with it -- but that particular behavior has been driving me nuts for a while. They really need to fix it.
"AV makes any computer slow" is still true. Scanning every file every time it's accessed simply can't take zero time.
"But think of the security!" they'll say... of course, it's always a tradeoff. I've experienced a similar problem with a large growing logfile --- appending becomes essentially quadratic, every time the process closes the log the AV opens and scans all of it.
Exactly.
I first noticed it when I would open my downloads folder (because I'm a heathen and never clean it out), and it would sit there and "process" for fifteen minutes. Just clicking realtime protection off fixed it instantly -- but it would seem there's no need to re-scan every file every time a folder is opened, scan them when I click on them, or scan them when I try to open them, or scan them in the background while I still can interact with the folder. Being unresponsive is a cardinal sin for any UX, and that's where Apple shines and MS still continues to drop the ball.
Like I said, I really like Windows 10 -- but it really falls short here.
Oh god, that's exactly what I have. There's nothing we can do short of disabling defender? Are there AVs that are as secure and don't slow explorer down as much?
