I am no longer getting the thumbnail previews on my taskbar. It may or may not be related that when I booted up this morning, I got a blue screen (I didn't watch the boot process - not sure when it occrured) and had to reset the PC.
I have tried the four solutions here to no avail: Taskbar Thumbnail Previews - Enable or Disable
Except 1 because the homepage is down and the alternative source which I found is a .php file which I can only seem to open in gpedit or something and 2 because it doesn't apply.
Please, how do I enable my live thumbnail previews? I don't think I could have done it inadvertantly, because I haven't been toying with any settings.
