Interception driver details

capsicain requires installation of Interception, which installs a "keyboard upper filter driver".

This adds a driver file Windows/System32/drivers/keyboard.sys

and changes in the registry entry Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{4d36e96b-e325-11ce-bfc1-08002be10318}

the item UpperFilters to keyboard kbdclass

where keyboard is the Interception driver, and kbdclasss is the standard Windows driver. You may have other filter drivers installed. Key events pass through the driver chain in this order. I do not know what happens if you change the order manually.
