Windows key "stuck" in Remote Desktop...
You think keeping up to date is a good idea, however, the last version of RDC now has an annoying bug. It seems if you use the Windows-L combination to lock your machine (in person), the next time you connect via Remote Desktop the system acts like the Windows key is stuck. I don't know if this happens 100% of the time, but this has been happening to me now consistently for over a week and I finally remembered to see if it is truly an issue or not.
Sure enough, tons of other people have complained, but there doesn't seem to be a permanent fix. There are a couple options - a "soft hack" method where you use the On-screen Keyboard and just click the Windows key on/off, a registry hack that will disable the Windows keys altogether, and quite possibly downgrading to the slightly older RDC version.
Here's some relevant threads. The OSK idea works simple enough; however it shouldn't be an issue no matter what, especially since the Windows key is not passed through RDC anyway.
Hopefully there will be a proper fix soon. I'd rather not have to disable keys or manually have to click buttons every time I connect via RDC...
