Windows 10: After Creators Update 2 thumbnails cache keeps auto-deleting

Nope still doing it *Sad Came across a folder with some mkv vids in it only 5 folders and it fell over again...

 

I created an account to say thank you and let you know that this has - so far anyway after 24+ hours - worked for me. I'd been trawling Google and help forums trying to get at the solution. So I'm gonna put a big ol' SOLVED in this reply and in the title hoping that keyword attracts anyone else on the hunt for answers. Much appreciated!

 

Hi. I found this thread yesterday and applied the DWORD suggestion on my desktop PC. Now when I check task scheduler, I am seeing the operator or admin has refused the request under disk cleanup, see attached image. With DWORD set to default, it says operation has completed successfully. Can anyone who applied the DWORD suggestion confirm this? Open task scheduler, go to Microsoft, Windows and Disk Cleanup. Thanks.

 

I’m not at home to check but I think that is a misleading report from the scheduler. I did the registry edit and can confirm disk clean up still seems to be working via automatic maintenance. After the last cumulative update I left the pc idle and after returning to it I noticed I got some disk space back so it appears it is still working and only suppressing the thumbnail cache deletion. But I’d be very interested to see what others are seeing relating to this and whether their disk clean ups are still working automatically

 

Yes, there is! I too am a photographer and videographer with tons of files. This building and rebuilding of thumbnails was driving me crazy. Finding this solution should hopefully be the last part of the equation. The first part is to increase the size of the thumbnail cache. The default in windows 10 is 550 mb (or just over .5 gb). I'll show you below how to increase to 4 gb (or more if your want).Increase Icon Cache Size
*Arrow Icon Cache Size - Change in Windows - Windows 7 Help Forums

To begin, first create a system restore point. Should something go wrong, you will be able to restore your computer back to this point.Having done that, open WinX Menu and select Run. Type regedit and hit Enter to open the Registry Editor.Now navigate to the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ExplorerNow right-click and create a new REG_SZ (String Value) and name it Max Cached Icons.Give it a value of 4096 (4MB) or 8192 which is 8MB.
Save and exit the Registry Editor and restart your computer.
See if this gives you positive results.If the results are not to your expectation, you may delete the created REG_SZ (String Value) or change its value to 500, which is the default value.
You may also restore your computer to the created restore point, if you wish.

After this I read in various other places that it is best to put a value of 4096 there. Anything above that actually cause performance issues. So, I would start with 4096 and see what happens. If you run out of space try doubling and see what happens. This will take you from the default of 550 to 4096! This is over 8x the size. After I did this, I went in I went to this folder and kept it open as I went to various folders with pictures and videos and watched it grow and grow. Your getting 4 gb of cache so hopefully that will be enough.

Good luck!

 

Thanks for this my setup is still struggling after the 1709 update, so i will try this next.

 

Twice a year, when Windows is upgraded to new version, all thumbnails will be lost again.
Many other settings and configurations are also lost - every time.
Dear Microsoft: It's completely untenable.

 

Yep, drives me crazy. This registry edit will have to be re done with the next feature update. Why they have to roll out so many updates is beyond me, they seem to break more than they fix. This bug for example will probably never be fixed by MS

 

Not helpful I know! But I have 3 PC's, a desktop and 2 laptops running Windows 10, all fully updated, and I have no problems with updates or thumbnails or anything? Should I complain to Microsoft?

 

This is a serious problem for any photographer. I had just rebuilt an image cache in a folder when an update killed all my thumbnails all over again. I have followed the instructions in this PC World article -- and it works, but only until the next Windows update.

I'm on a Dell XPS 8900 with a Core i7 processor and 32GB RAM. Nevertheless, all work on photography must come to a standstill as I plod through the rebuilding of my thumbnail cache, row by row. Even if you let the thumbnails rebuild in small view, you have to wait all over again if you want to switch to very large thumbnails. This is a nasty fricking bug!

 

If working with a lot of images why not just use a dedicated third party image viewer that can use it's own dedicated thumbnail cache?

 

YES. Thank you. Tried so many things and this finally fixed it. I've submitted feedback using the feedback hub on this, referencing this solution and hopefully MS will get this resolved for the next update.

 

Mines not fixed with that reg hack. Something else is up, but it definitely still relates to the thumbnail cache.

 

I should look like then. . . correct ?

 

Yup.
