Office Software Protection Platform - Sichert die Integrität von Microsoft Office
It is a really "uncool" file. First of all it is a memory eater/ And for some reason my internet doesn't work with it (it may be from my PC, but the file can be affected)

Die vorherige Bemerkung ist nicht korrekt, osppsvc sichert die Integrität von Microsoft Office nicht. Es wird lediglich die Lizenz geprüft. Für den Anwender völlig überflüssige Belastung des Systems.
ga spy, it spies on all your keyboard activities
eats memory and bandwith at startup

Best practices for resolving osppsvc issues

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