Missing, disappearing folder thumbnails only from the Desktop

I started getting headaches troubleshooting this problem and I was kinda on the verge of stopping this until I accidentally found probably the best temporary workaround.

The problems seems to be fixed if I open a new txt doc, click on save as and as the save as dialog opens up, the desktop location is the default one, on this window the thumbs appear and then a single refresh on the actual desktop, not on the save as dialog box desktop, fixes the problem. Of course, fixed until there's another change of content in a folder.

[edit] This temporary workaround kinda stopped working. It appears that it only works if all the files go into their original folder.

This above might sound confusing, if you didn't understand me say so and I'll record a video.
Scratch that, it's simply weird, sometimes work sometimes doesn't.

As for the process monitor, I was doing exactly the same thing you were doing on both accounts and the differences I was able to get are

A = main account, thumbs dont work
B = 2nd account, thumbs work

In A this folder was called
C:\Windows\winsxs\x86_microsoft.windows.common-controls_6595b64144ccf1df_6.0.7601.17514_none_41e6975e2bd6f2b2
in B it wasn't.

and in A this file was called C:\Users\MyName\Desktop\desktop.ini
but I have deleted it and ProcMon says NOT FOUND
I have also deleted that file in B but ProcMon didn't say it was called

Yup one says Icon Cache and the other Thumbnail cache.

Hi uchkur, fancy meeting you here

Since it works correctly with a new account, what about keeping the new account and copying everything from the old account to the new one. Then if all is well, delete the old account????????

See here: Fix a corrupted user profile

You can also use the Windows Easy Transfer to transfer your profiles and settings to a new account:

1. Go to Start –> type Easy Transfer –> Click Windows Easy Transfer in the search results.
2. You will get a welcome message to Windows Easy Transfer. Click Next.
3. Choose a different partition or internal hard drive, external hard disk or USB flash drive. Can't be the same drive you are transferring from (the "old computer").
4. Select This is my old computer.
5. Check the box before your current user account, and click Next.
6. You can input a password if you want.
7. Click Save to save the transfer file. The transfer file will be a single file with the extension .MIG. Please remember the location.
8. Create a new account via Control Panel - User Accounts.
9. Log off the current account and log on the new account.
10. Open Windows Easy transfer again and click This is my New Computer.
11. Choose "Yes, open the file" to navigate to the .MIG file.
12. Check the box before your old account, then click the Advanced Options above the Transfer button, then you choose which user account you want to transfer.
13. Click Save and Transfer. Now, you can see what are the files that were transferred.

Test if everything works correctly in the new account now. If yes you can delete the old account via User Accounts.

If not, please delete the new account via User Accounts. Go back to step 8, and repeat the step 9 and 10, then check the box before your old account, and click on the Customize button next to this old account, and uncheck the box before Windows Settings, then click the Transfer button.

I seem to have lost the site this came from originally, sorry.
