1803 messed up my video thumbnails
I upgraded to 1803 on 2 pcs and since then only half my video files have thumbnails. Doesn't seem to be a particular file type - some mp4s are affected, some not (ditto mkv, avi). I have the relevant (show icons never thumbnails) boxes set correctly. I don't think it's a codec issue since, although I have VLC as default, all videos play in WMP. I don't have any codec packs installed.
Just to confuse things further, which files have thumbs is different on each pc. If I transfer half a dozen files from pc1 to pc2, which file has a thumb changes (the machines have different hardware but identical software).
I wish I could permanently opt out of these upgrades - there doesn't seem to be any difference at all after any 'upgrade', apart from stuff gets broken - eg networking in explorer is now broken on my little render farm. That'll take a day to fix.
Now where did I put that Windows 7 disk ...
