I bought a new laptop with an Nvidia GeForce 4070 GPU and an I7 12700 CPU. After installing Microsoft Office products, the service sppsvc stopped working as a result the Office apps raised the error "Office needs repair" and then after clicking on repair like online or offline, nothing happened.

I tried to restart the mentioned service and I encountered the following error:

I decided to try anyway to start again that service and resolve the given error.

The summary of my attempts after many reinstalling of wnidows from scratch:

  1. I disable Driver Signature Enforcement via recovery.

  2. I changed the value of the key InactivityShutdownDelayComputer at \HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform.

  3. I checked Task Scheduler to find a task relevant to it but there is nothing to do.

  4. I installed the latest updates.

Any idea to solve this problem is appreciated do.

The Software Protection service (sppsvc) cannot have a bad digital signature. It's a major part of Windows and is defined as:

Enables the download, installation and enforcement of digital licenses for Windows and Windows applications. If the service is disabled, the operating system and licensed applications may run in a notification mode. It is strongly recommended that you not disable the Software Protection service.

In sort, it's one of the first protections that a virus needs to disable when it takes over a Windows system.

There is a very good chance that your computer is infected.

As a first measure, I suggest to test Windows integrity and perhaps somewhat fix Windows by running the commands Dism /Online /Cleanup-Image /RestoreHealth followed by sfc /scannow and by doing deep antivirus scans by more than one vendor (only download from the vendor's website).

If this is not enough, the re-installation of Windows will be required.
