This solution is the only one that works and its hassle-free...at least for a while. As Girish M advises on another thread, take the following steps:
- Hold Windows key +R.
Copy and paste, or type the following command in the Open box, and then press Enter:
services.mscIf you are prompted for an administrator password or for confirmation, type the password, or click Continue.
- In the Services list, double-click Software Protection.
- In the Software Protection Properties dialog box, click
Automatic in the Startup type list.
- Click Start in the Service Status, click Apply, and then click
OK.
I had done the above previously and still have the problem recurring but less often. Was unable to upload a screenshot so you can see that you will probably not be able to make the changes to the Software Protection Properties without
rebooting. So jus save your work, reboot and BEFORE starting up any Office app, make the changes and reboot your system.
Why does the Software Protection****service stop working? I'm searching Google for answers. Stay tuned.
