I got a Windows Update the other day which in turn,the Advanced Micro Devices, Inc. driver update for AMD Radeon(TM) R7 Graphic was installed on my desktop. Right after this update completed, the next time when I booted up my PC whereby it took seconds for the login screen to come up on my monitor, it now takes about two minutes instead. I also noticed that when I look at Device Manager, display adapters, there are now two listed. The new one and I'm assuming the old one - AMD Radeon R5 330. My question is if I were to unistall the R7 adapter, would that screw up my desktop.
