Actually its true that Windows Update causes this AMD driver and Software errors!!
I have the same issue now for about 3 weeks. I had to REINSTALL AMD driver every 2-3 days. I notice that everytime I reinstall AMD driver, after 2-3 days Windows Updates automatically installed graphic driver called "Advanced Micro Devices, Inc. - Display - 27.20.21034.37 ". And AMD software couldnt be launched anymore!
Solution is that you just roll back driver to previos version and AMD Software will work again even without restarting computer!
For now I disabled Windows updates and I will check later if Windows Updates want to install this bad driver again.
