ha ha, I understand, the problem is that Microsoft has too many issue to fix. But let's hope it's really one of the few, I just need to solve last my issue and then Sp3 will be perfect again. Today worked fine.
Keyboard with setpoint disabled gave less troubles, happened the disconnection only and caps lock stuck only, but not the kkkkkkkkkkkkkkkkkkkkk or unresponsive like when it's enabled the setpoint. If you open setpoint you will see that the keyboard is not listed, and get stuck setpoint when it see the keyboard, then disappear etc,
have you disabled it, yes? however, generally I could work well all the day with the keyboard, the issue it's not so bad at the end, could go even worse........ at least I'm able to work. So let's wait the fix.
