Do not disable this service or delete it by any means. If you do so, Windows activation, Office activation, etc. will fail. You will see activation watermark on the desktop. I have seen a lot of reports about it, and its not a good move, unless you are not bothered about it. There is a registry key hack (HKLMSYSTEM\CurrentControlSet\Services), and if you alter it any way, you may not be able to restore it.

The chances are that if Sppsvc.exe is causing High CPU usage, it means that it is stuck with validations, and is not able to complete. We have noticed users reporting it with 30-40% CPU usage.

The last action will make sure to stop the Microsoft Software Protection Platform (sppsvc.exe), and other related services stop. Note: There is no way to disable this service, and change the startup method.
3] Scan & Check for Malware
Rare, but its a good idea to check if the file has been replaced by a malware. The best way is to check the location of the running sppsvc.exe. In the Task Manager, right-click on sppsvc.exe, and choose to open the file location. Validate if it is C:\WINDOWS\system32\sppsvc.exe. If yes, then the file is good. If not, then you should immediately delete it. There are a couple of ways to do it depending on the situation.
Try deleting it directly.Boot into safe mode, and then delete it.Use a third party anti-virus to get rid of the file.
Lastly, since you have deleted the file, use DISM to restore the files. DISM uses Windows Update client, but you can use a Windows side-by-side folder from a network share or a removable media, such as the Windows DVD or USB media.
4] Check Windows Activation Status
Did you notice if your copy of Windows had an activation issue before the CPU usage went high? It is possible that Windows Activation service is not able to validate Microsoft software or Windows itself. If you have a KMS or MAK key installed on your computer, you might want to verify the validity of the keys. KMS keys are still easier as you need to connect with your corporate server to authenticate. But in case somebody has sold you MAK key which is no longer valid, you will need to buy a new key.
