Hey People i resently upgraded to windows 10 and so far i like the OS, but small things seems to bother me.

First of all am I unable to right click my icons in the taskbar in order to get the menu of the given program to pop-up.

Second thing is sort of similar, sometimes am I able to open the startmenu and search, but only occasional. For the most part am I unable to open them at all, not even with the windows key.

Third thing is, it seems that I'm unable to install my Geforce gt 630m windows 10 driver. The installation tells me that it was unable to install and that I needed to restart my system and try again. I tried so several times and with no further success.

I know it might be to many things but i would really appreciate some advice or help in terms of solving these small but important features :)
