Microsoft Software Protection Platform Service
In principle, monitor the SPP Notification Service (Software Protection Platform), the activation of the license. Who the service through the surface (services.msc) or the built-in command-line tool (sc) is disabled and the associated files (Slui.exe, Sppuinotify.dll, Sppwinob.dll, Sppsvc.exe and manifest files in the folder SPP) to acquisition of the rights to rename or delete, etc. Basically, its Windows "noid" program. It likes to annoy people with cracked versions of windows. Keep your eyes open. There are plenty of ways to crack the validation again without having to "clean reinstall"

Required for windows xp and up
If this is on the Windows Server, it should be left along as it is a Microsoft Process for Key Management Service

although it could be important for microsoft, but it uses too much cpu.
uses wayyy too much resources to check for licences, should be disabled out of principle just because of that. Needed for office

Best practices for resolving sppsvc issues

A clean and tidy computer is the key requirement for avoiding problems with sppsvc. 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 repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
