Keyboard shortcuts not registered

Since recently, it happens that my keyboard shortcuts are no longer registered.
for instance, i have a print screen tool which registers the PrtScr key to run.
I also have other apps running that register hotkeys (ctrl+shift+alt+d for 1password in my browsers)

Most of the times, when I am booted, these hotkeys do not work. Sometimes, rebooting solves everything, and the hotkeys work again, but after reboot, this fails again. Most of the times it does not work though.

I don't see anything in my event logs that could point me in the right direction.

Next to that, sending keyboard combinations to the remote computer using remote desktop connection doesn't work either, all are executed locally.
I do not know if that is another problem, or if it is related. If not related, I will create a separate issue.

it's a laptop, i do not mean hotkeys as in hardware keys on the keyboard, but as in windows key combinations

ctrl+shift+alt+D
PrtScr
...

I did a full mallware/rootkit/virus scan on my laptop with several different tools already as well.

Ah right,

I'd go with uninstalling the keyboard and reinstalling, If that doesn't work still attach an external keyboard, if that doesn't work then you may have sticky keys on which are causing the problem.

Click start, programs, accessories, accessibility and it's in there.

Regards

Alex

sticky keys are not on.

The system automatically reïnstalled my keyboard, without a problem.
The hotkeys still don't work sadly.

I did notice a few times that my explorer crashed because of some dll. This was apparently the VC++ redist, there were about 15 vc++ versions installed. They have been uninstalled and the explorer crashs does not happen anymore.

Before I had 1 time that the hotkeys that my apps registered again, then my remote desktop keys were send as well. (eg. windows key).

So it seems that those are related... which means that mstsc isn't able to "register" windows key and such at that time either to send to the remote computer.

I think i found the solution.

I recently installed synergy, which allows to share you mouse & keyboard with another computer, by using the second computer as a "second screen".
When that is started, the hotkeys are captured by that tool and not sent locally
