Explorer.exe - File System Error (-1073479340)

swerd · Apr 20, 2026

Hi everyone,

I am getting this pop-up when Windows starts.

I have tried -

chkdsk /f /r (on both my disks)
DISM /Online /Cleanup-Image /RestoreHealth
sfc /scannow
Windows Memory Diagnostic

It still shows up. Does anyone have any ideas?

Cheers

Hi, noting you have 2 identical disks- are these configured as RAID or how?

I have tried -

chkdsk /f /r (on both my disks)
DISM /Online /Cleanup-Image /RestoreHealth
sfc /scannow
Windows Memory Diagnostic

- but you've not specified the outcome.

Do you mean...
- you ran them and one or more failed?
or
- you ran them and they passed or fixed something, but you still have the same problem?

Try Crystal Diskinfo (free) and check its report on both disks. Portable version available. Simply launch it and look.

Note that in this instance of the same error number an in-place upgrade repair install which keeps progs, accounts and data was not possible:

I don't have two identical disks. I have a 256GB NVME SSD and an 2.5" HDD (4TB).

I mean this. I'm not sure if chkdsk fixed anything, but the others all ran successfully.

That is strange. I can remember one or two going back months. Could they be something else?

zbook · Apr 20, 2026

Today is 04/20/26.

There were multiple BSODs and live kernel events per day.

Really? Your specs say

And thank you for your reply.

Those specs are for my desktop machine; I'm on my laptop. They are also very out of date.

EDIT - Now updated

Posting about a different PC to that in your specs is bound to leave people guessing, now isn't it?

Yes, my fault. Fixed Now.

I rolled back my Windows 11 install to a backup about a month old. Everything seems to be working fine. If I have the same problem again, I will reply to this thread.

Thanks for the help!

swerd · May 1, 2026

Well, in the end, it came back. I asked Claude what to do, and it suggested uninstalling any shell-altering apps I had installed. So, I uninstalled Start 11, and it's gone away, it seems for good now. Thanks for all the help!

dalchina · May 1, 2026

Good. If Start 11 is causing issues- try Open Shell instead. Recommended by many (free).

install StartAllBack and see if you can replicate it again with that

Start11 = Stardock product; StartAllBack is different.
