In Windows 10, open the View Tab in the File Explorer ribbon and there you will find the option of Preview Pane in the top-left corner.

Now it’s not that the preview feature is entirely missing on Windows 10, but it’s not as streamlined as you would find it on a Mac. Moreover, if it’s a ZIP file, you get to know the content of it without even opening it, which is great. This is a quick way of getting a preview of multiple images, videos and even documents without using many resources. The system will do the rest.Ĭheck back again on Windows Explorer, and you should see your PDF thumbnails appear again.In Mac’s OS X, you can select almost any file and simply press the spacebar to get the quick preview of the file before opening it with the default program. Simply run Disk Cleanup, select the C drive, put a tick in the Thumbnails checkbox, and then click OK. If it still doesn’t work, you may also have to clear your thumbnail cache, but don’t worry, this is very easy to do. Click “apply fix” and then restart Windows Explorer. There is pretty much nothing to configure–no options or anything. Simply do the usual download and install and when you start it up, you will see a small window. Anyone with either Vista or Windows 7 64-bit may also experience this problem, and 64-bit Adobe Preview Handler is here to save the day. The issue of disappearing thumbnails doesn’t seem to be confined to just Windows 8 though. This small app (which weighs in at a measly 1MB) makes a small Windows registry fix that brings your PDF thumbnails back. The app itself is just a simple box which can be closed, once you click the “apply fix” button. So I did my usual and went Googling for answers and ended up with a free program called 64-bit Adobe Preview Handler. I couldn’t even get the standard Adobe PDF logo. Normally, when I view an Explorer folder, I have the PDF files on “view large icons” (as it then gives me a preview of what the first page of the file looks like). The thumbnails for all of my PDF files disappeared. When I upgraded to Windows 8 64-bit a few months back, a strange thing happened.
