AltGr key broken after 4.3.28 install and can't get it back

[ric_vbox]

Hello,

after installing virtual box 4.3.28 on 8.1 and an english debian wheezy os guest, my AltGr+1 / AltGr+2 / AltGr+3 doesn't work anymore. Very very very annoying as these are used quite often on a french keyboard. A lot of threads on this, supposed to be fixed and then pop out again, and fixed again.... and now officially fixed ? (michael?).

My keyboard is more important than virtual box so i decided to uninstall everything related to vb. No luck, my keys are still gone. Then i tried to see if some drivers were left behind.

And yes, that sounds unreal, but there is files and registry keys left after uninstallation in drivers system folder, for me :
vboxdrv.sys
vboxnetadp.sys
vboxnetflt.sys
vboxusbmon.sys
vboxusb.sys

and some reg key as well but not all :-/

I wonder why these files are still there but anyway i deleted all of them and still no have my keyboard back. Btw, at this point there is still vbox stuff in fs and registry on my system but i gave up.

So my question is quite simple. Did VB wrecked my windows OS or is there anyway to get my Keyboard back ?

Maybe re-installing an older version of vbox that works or ... any suggestions are welcome (other than re-installing windows).

Is your keyboard layout still set to French?
I often switch accidentally, still don't know how it happens.

[ric_vbox]

Yes it is, french is the only keboard layout i got installed.

The drivers should have nothing to do with this. Does the problem persist after you re-start your host system? And if it does not, does it re-appear if you re-install VirtualBox without starting any machines? (It really shouldn't.) And after starting a machine? And then after stopping the machine and possibly re-starting your host?

[ric_vbox]

Yes, it is persisting across restart.

I re-installed VB, he found out my old image. I just restarted the host, didn't start any guest, no luck. Then i started my english keyboard debian image. No Luck. Then shutdown the image, still no luck and same after another host restart.

Any logs I can activate to help understand what's happening ?

[michael]

If the problem occurs when VirtualBox is not even installed and after you re-started your physical system then I don't really know what to suggest in the way of logs. Do you happen to have any other software installed (or might something you are not aware of be installed) which might be manipulating the keyboard?

Actually, did I understand correctly that AltGr is not generally out of action but just some AltGr combinations?
