Windows 8.1 error

Hi guys,

I have just installed the windows 8.1 update, installed few programs but unfortunately after a simple restart, win 8.1 does not longer load and I get a lovely blue screen with the error BAD_POOL_CALLER displayed.
After several attempts I have managed to load the system in safe mode and uninstalled all programs previously installed, but unfortunately the error is still there.
Could you please help me?
Please find below the link to a minidump file I have collected:
