Windows Explorer often freezes when moving files with mouse

Try this.

At Admin command prompt, copy and paste this and run it.

Dism.exe /Online /Cleanup-Image /RestoreHealth

Then, run sfc /scannow again. Let us know if it fixed anything after the second SFC. Thanks.

Here is the DISM tutorial that should provide you the information you need.

Use DISM to Repair Windows 10 Image


If you have 1809 boot media it may be simpler to run an inplace repair

Repair Install Windows 10 with an In-place Upgrade


If you don't have 1809 media following the inplace repair tutorial with new media will result in you upgrading to 1909.


Are you still running 1809 for a specific reason?

Suggest you perform a basic check on your disk, then on your file system.
a. Get a copy of e.g. HDTune (free) and run the checks from the Health and Error Scan tabs.
b. If ok, then from an admin command or Powershell prompt run
chkdsk c: /scan

This checks only. Post back if it fails.

You can get an iso file for 1809, should you wish to stay with that almost obsolete build, by searching for
Heidoc iso downloader
and using that.

It can take up to three runnings of sfc /scannow to fix issues.

After that it is time for a different fix.

After re-running SFC /scannow I get this message: "Windows Resource Protection found corrupt files and successfully repaired them". I haven't yet dared to see if the problem is fixed because I could lose this thread if it isn't. I will report back in 1/2 hour or so to say whether it has been or not. By the way - astonishing support from you all!

You should reboot (restart) now to ensure the fixes remain fixed. After reboot, run SFC one more time to make sure it comes up clean. Only takes a few minutes. Let us know, Thanks.

Thread isn't going anywhere. We'll be here.

Please do not skip the elementary checks in my post #4 - just in case. No point in trying to fix files if there are more basic problems- that's building a house on sand.

@hjpatten

Have to go for a while. Please make sure you have rebooted after the SFC has reported no errors and before other steps that may be needed. I'll check back later. Good luck.
