Windows 10: File Explorer Unstable

Symptoms:

I first noticed that the thumbnails for my picture files weren't displaying. Then I found that they weren't previewing either. After changing the folder view settings to see what would happen, the folder view settings greyed out and were unresponsive. Closing and opening File Explorer once or twice resulted in the navigation pane not showing anything other than the Quick Access. After that, icons of running apps started going blank on the taskbar.


Things I've done:

1 Cleared thumbnail cache.

2 Checked view settings.

3 Run a system scan sfc /scannow. This said that it fixed a few problems.

4 Restarted Windows Explorer task - several times.

5 Scanned for viruses Avast and Malwarebytes

6 Rebooted.


Rebooting makes it work for a short time, then it starts acting up again the same way. Interestingly, I found that Open and Save forms seems to work okay.


This is what Explorer seems to be stuck on:

File Explorer extremely slow and unstable.


So I just took part in the Windows 10 Insider Preview a couple of days ago, and I have to say, Windows 10 is a great step up from Windows 8, they did an excellent job so far. There's just one problem: File Explorer is extremely hard to use. Not only does the file explorer freeze all the time (even on folders with almost nothing in them), when it does freeze, it goes back to the top of the folder when it unfreezes.

What I mean is that I can be half-way down a 260-count file folder, like this:





Then it will freeze, and after it unfreezes, it goes back to the top of the folder, like so:





Doing simple tasks such as moving, copying, renaming, deleting and even scrolling and clicking causes File Explorer to freeze, sometimes even when it's idle!

And what's weirder is that the glitch doesn't happen when your opening a file for a specific program (say you click 'open' in Word and you get the 'Open' dialog box where you can pick a file).

I posted this over to Windows Feedback too, but I don't think it supports user comments, so I'm posting here to see if there's any fix. If there's any fix for this, let me know. It's been annoying me for a while now.
