It is related to Windows Live Messenger. However, very recently it has been causing problems with my Windows Live Messenger.
live messenger
Caused key/mouse inputs to become scrambled and behave erroneously (as if ctrl key was held) even after reboot. Ending process fixed issue
it is a windows live messenger service, if you experience problems with the amount of memory that this file uses than just exit the Windows Live Messenger, not just to close it... right-click on the messenger icon on the taskbar (most of time is near the clock) and click exit. Hopefully this can be helpful.

Wlcomm[1].exe is the dangerous one! I even have it as a virus.
When i close it, the winlive messenger diconnecting
It's a background task responsible for synchronizing your Live Messenger contact list. If you have recently connected your Live Messenger client to Facebook or other social media, it is this very association that caused the increase in processor utilization. My suggestion is you disassociate from all social services and run as a stand-alone MSN Messenger service and your system performance will return to something close to normal. And, perhaps MS will find a way to troll poll these sites with fewer CPU cycles in the future. WLCOMM.exe belongs in C:\Program Files\Windows Live\Contacts\ only.
