Fast-user switching & Fast startup unusable

HellboundHeathcliff
When logging into a second account using fast-user switching, the taskbar, including the system tray will be blank. It is impossible to interact with windows when this occurs other than to use ctrl-alt-del to log out. Logging back into the original account will many times then behave the exact same way. The only remedy is to ctrl-alt-del then logout and restart the computer. Many times when looking over the event viewer, I see that explorer.exe had crashed into some sort of crashing loop. The Naga Pro mouse OR my Huntsman TE keyboard cause the problem. Through much trial and error, I narrowed it down to these 2 specific pieces of hardware. Other Razer peripherals I own and tried out did not cause this issue. Admittedly I did not try them all. When BOTH the Razer Naga Pro mouse AND Razer Huntsman TE keyboard are connected, the problem is worse. Logging out before logging into a different account (slow user switching) will often cause the same issue. Having Fast Startup enabled will occasionally cause the same problem at login after a startup. Again, through trial and error I found that disabling Fast startup will eliminate this issue although it is only a workaround. Not using fast-user switching at all is only a gamble whether the issue will present itself when logging into a different account.
