I have very long Windows 7 uptimes - many weeks. I would have them much longer - I need it for my workflows.

The only trouble which forces me to restart: Alt-Gr loses its function, and then I can't have signs like @ or . After rebooting the OS, all keyboard functions are back - until the machine decides again "oh, I've been working too long, it's time to cancel the Alt-Gr functions"... Grrr.

What is the problem? Can i get Alt-Gr functions back without to restart the machine?

    Does the workaround Ctrl+Alt+key also cease to function? – LotPings Nov 9 '18 at 15:26
  • Wow, nice workaround :) thank you - yes, it works... Well, now is the pressure to restart is a bit away:) – Evgeniy Nov 9 '18 at 15:45

Your problem may be related to remote desktop connections. In my case, the problem was solved by logging back into locked remote connections.

    it could indeed be true - i'm really often logged in into virtual machine running on remote hardware... Would never thing about this as a cause for the keyboard problem. Interesting. If getting this issue next time, will check, whether your workaround gives the light. – Evgeniy Nov 21 '18 at 14:54
