This tutorial is an extension of the tutorial we wrote ago: Disable and delete the thumbs.db files in Windows 7
The reason behind writing this tutorial is, Windows 7 Home Premium does not have Group Policy Editor. So, we need to tweak it from Windows 7 Registry Editor.
Do as said in that tutorial before the point “Disable these files”. Now you need Windows 7 Registry Editor to do the work, instead of Windows Group Policy Editor (GPEdit.msc).

Click the Start button and type Regedit, press Enter from keyboard and accept any security prompt:

Windows Registry Editor will open; Navigate to :
HKCUSoftwareMicrosoftWindowsCurrentVersionPoliciesExplorer
Now, create a 32 bit DWORD there name it “NoThumbnailCache” by right clicking on the right sided pane:

Double click and setting its value to “1” .
Exit Registry Editor. This is it.

The above is very clear, but unfortunately on my 64-bit version of Windows 7 Home the folder
HKCUSoftwareMicrosoftWindowsCurrentVersionPolicies
contains no sub-folder Explorer in which to create the required DWORD, and there’s no obvious option to create such a folder. Is it at all possible to disable the creation of thumbnails in this case ?
On the left hand pane, right click on the “Policies” > Hover over “New” option > Click “Key” . Rename it as “Explorer”. Then do the of the rest things.
I see. What I was calling a ‘folder’ is actually a ‘key’. That’s certainly elucidating! Now I think I know what to do.
Thank you very much indeed.
You’re welcome.
Right. They looks like “Folders” but actually they’re Keys.
Do you still create a 32 bit if I have a 64 bit Home Premium OS?
