Runsa scheduled Dell Datasafe Local Backup. Important if you want to back up. Runs VERY slowly so may be visible for many hours!
This program freezes the EverQuest Landmark ALPHA program for several seconds every 60 seconds. The computer is working correctly, and this only happens with this ALPHA game. The service can safely be stopped while playing.
On my system it is part of Dell DataSafe Local Backup. This program can be replaced by Dell Backup and Recovery (a newer version), which is made by the same vendor (SoftThinks). It is needed for Dell's backup system if you want to schedule backups. It can be uninstalled by uninstalling Dell DataSafe.

Best practices for resolving STService issues

A clean and tidy computer is the key requirement for avoiding problems with STService. 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. 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 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
