Sppsvc.exe is the executable name for Software Protection Platform Service. This is the licensing service for Microsoft software products.
Note: It is strongly recommended to use a genuine copy of Windows 10 for your system.
One of the main cause behind high CPU usage by Sppsvc.exe is that the copy of Windows might have been activated using a third-party software like KMS. Another case might be that associated Microsoft applications might be activated with software like KMS even if the copy of Windows is genuine.
If your copy of Windows is genuine yet the KMS is running in the background, it would interfere with the Software Protection Platform Service this causing high CPU Usage by Sppsvc.exe.
If we disable the Software Protection Platform Service, the system would display an Activate Windows watermark on the bottom-right corner of the screen and users might face other issues as well.
1] Update Windows just in case it’s a known bug for your system and Windows rolls out an update to fix it. Here’s the procedure for updating Windows.
2] Scan your system for virus and malware.
