It is related to Windows Live Messenger. However, very recently it has been causing problems with my Windows 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.

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.

Best practices for resolving wlcomm issues

A clean and tidy computer is the key requirement for avoiding problems with wlcomm. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the wlcomm.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
