So I recently installed the Windows 10 preview to try out and when I tried to customise my background with the usual background slideshow I use on Windows 7 the folder I choose to use does not work. This goes for both desktop and lock screen. Fortunately I found a work around with the main desktop and managed to get that working but I am unable to do the same with the lock screen. Was wondering if anyone had the same problem and was able to fix it.
Also, it's probably just my computer but when the background does change it also changes the colour theme (which is great) but I find it lags when switching. Just my computer or anyone else experiencing it?
EDIT: Appears to be working now
