The trouble started when i played around with "Task view button" normally i have it unticked but i ticked it and tried right clicking the task view and selecting "show windows side by side" nothing happen and i worked another hour on What an absolutely useless and misleading reply, i bet 99% of the above have not changed that setting, now i know what caused it but MS need to make a small update to fix the problem with the other updates that should fix the first update
