Volume Shadow Service ok.
This service manages the "perfect image" backup of volumes that have files in use (opened) while the backup is going. It ensures that applications can continue writing data during the backup, that files that are opened are not omitted by the backup, and that backups can be performed at any time without locking users out. Recommendation : It is not possible to backup open files in Windows XP/2003 without this service running, so, if you use backup software, leave it running. If you have no use for this service, disable it via the "Administrative Tools \ Services" icon in the Control Panel.
is a required backup process for systemstate backups
This service is fine, normal, expected, etc. Good for backing up locked file types.
It started running on my PC, once I started installing VMWARE tools on guest operating system hosted on ESXi Server.
Felix is right-on with his assessment. If you feel that this file may be corrupted, from an administrative prompt type: sfc /scanfile=C:\Windows\System32\VSSVC.exe
On a weekly scheduled basis, vssvc.exe is captured in the event system log as one service running, attempting logon but failing. In services, it was set as a manual start. In the Scheduler, Windows Backup is not scheduled but the unscheduled event triggers for time match the time of my Windows 7 system locking up requiring a power cycle. Additionally the Windows 8 Backup is defined to backup to a removable Drive not connected Lockup happens with or without the remote drive connected. To isolate, in Services, volume shadow copy & windows backup have been changed from manual to disabled.

Best practices for resolving VSSVC issues

A clean and tidy computer is the key requirement for avoiding problems with VSSVC. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update.

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 6resmon command to identify the processes that are causing your problem.
