Win 10 file system crashes

Hello, if I understand this correctly, your file explorer is restarting.

This is not Windows per se, and this is not normal behaviour. It is most likely related to something installed.

So, a process of elimination.

1. Boot to Safe Mode. Try this for 'long enough' - longer than the time in which you'd typically see a crash. Do you observe any?
2. Now do a clean boot. (You can configure this from Safe Mode).

When logged in - again, give it enough time to see if there are any crashes.

You can use this time to look at
a. Your Reliability History (type Reli in Cortana's search bar).
Look at the red X's- click there and look at reports related to explorer.
Post a screenshot of anything that looks helpful.

(Use icon 'Insert Image' to the left of the video icon above your post to do that).

b. Also check your event log.

Note: When you do experience an explorer crash, note the time, as you can use the time stamp in the event log to find the right place to look.

3. If you are still experiencing file explorer crashes, download and install Shellexview (free).
Run that, hide all MS extensions, disable all other shell extensions (things added to explorer).

Now see if you have any file explorer crashes.

Note: some people find the next build upgrade introduces new problems. I've not seen reports of it fixing old ones that I can recall.
