Problem is at when double click it will start part of process (rundll.exe) and starts ocupying prosessor 50% then it needs to second double click to start et. Also when closing that et, rundll.exe remains running and taking 50% prosessor time. Other programs and games running normaly.
Fresh game, copy of et from memory stick all the same thing. Not sure when this started. All easy solutions is tested from windows side (reinstall windows is not an option). Same thing on my other pc and laptop also so its not just ops.
