Takes up lots of CPU resources, hard drive activity. Lots of network activity to another PC on my internal network using SMB protocol. Tree Connect AndX Request, The destination reported an Error: STATUS_BAD_NETWORK_NAME.. Saw activity with Ethereal / Wireshark. End Process Tree it all goes away.
It opened up a popup window that could not be closed, had to do a restart to get rid of it. It also seems to be a hidden file, doesn't show up on searches or in the subfolders I think it should be in.

Best practices for resolving CLMLSvc issues

A clean and tidy computer is the key requirement for avoiding problems with CLMLSvc. 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 CLMLSvc.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.
