Thumbnails Corrupted

It sounds like you may have to do a system restore again to get it back to normal(hopefully).

Hi SmithO, Welcome to Seven forums.

Try this. Icon Cache - Rebuild

Hope it helps!

Try either rebooting or logging off then log back on again after rebuilding the icon cache.

I had the same issues constantly and in the end after much research I decided that it's down to scheduled Windows maintenance. You can read the thread here:

Solution that worked for me is below. If you want to try this make sure that you can undo all the changes or make a system image backup first.


take ownership of this file (edit permissions):
C:\ Windows\ Diagnostics\Scheduled\ Maintenance\TS_BrokenShortcuts.ps1

Edit it by adding # in front of lines 44-49






and do the same for this file:
C:\diagnostics\scheduled\Maintenance\TS_BrokenShortcuts.ps1

but add # in front of lines 24-28



Disable the desktop cleanup wizard by opening Group Policy Editor (Start> Run then type gpedit.msc) Press Enter.

Navigate to:

User Configuration>Administrative Templates>Desktop

In the right hand pane, locate and double click on an entry labeled Remove the Desktop Cleanup Wizard.

Find Remove the Desktop Cleaning Wizard in the window. The current state should be Not Configured. Click on the Enabled option, click the OK button.



Additionally you can try the following.

Download Advanced System Tweaker

Backup the registry before doing anything else (From File menu)



Then run the program and find and highlight Disable Tracking of Broken Shortcut Links in the "Windows 7 System Tweaks" section and run that tweak only by clicking Apply in the right hand pane. Don't mess about with the rest of the tweaks unless you have researched what they do and why you might wish to apply them.



Also run the Windows Scheduled Maintenance Task in Task Scheduler manually after applying the above fixes. If your icons promptly vanish - set this task to disabled.



EDIT: Forgot to mention the following:

Create the following registry entries:

[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\ScheduledDiagnostics]
“IsBrokenShortcutsTSEnabled”=dword:00000000
“IsUnusedDesktopIconsTSEnabled”=dword:00000000



Reboot for changes to take effect.
