After doing a "save nothing" update from Vista to Windows 8 Pro, and installing the ATI CCC, Task Manager showed ati2evxx.exe using 85-99% of CPU. I disabled ati2evxx.exe and all ran as I expected, including the exclusive use of an external (2nd) monitor.

It can suddenly start using 100% of your resources. Go to services.msc and disable ATI Hotkey Poling which is not needed by most people.

Listed in Windows Services as: Ati Hotkey Poller. No hotkeys set - can disable it.

For some reason with remote desktop and local user sessions switching it periodically started increasing instances of this process. Session initialization especially for remote log in took tremendous time on my XP. Full computer restart was temporary solution. LOgon/logout/restart went veeeery slow. (tens minutes!!!) Everything is fine after I got rid of it (Hijack this - removed the entry + some unneeded service stopped). Those who have problem with long session log in/log out and remote sessions can take a look at this process.

This started take almost 80percent of my CPU suddenly. (May have some ralation with Open Office or Adobe Light Room)

If you're running the wrong driver for your ATI card then this program can malfunction. When it goes wrong it can take down an XP box.

it's the Ati Video Driver

No need to disable this program. It is needed by the display hardware.
