Some Microsoft Office Updates need a service to be loaded in workstations. The service name is "Office Source Engine" and in many workstations it is Disabled, so Microsoft Office Patches don't apply or don't work.
Here's a solution.
A good practice is to deploy a registry value that changes this Service to Manual State before Distributing the patches. The "Applicable" number of already distributed patches also change after the distribution of the registry value, so it´s useful to finally increase the "Installed" number.
The registry key and value are:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ose] "Start"=dword:00000003
Simply copy the key and value to a .reg file and use Deployment to apply it inmediately.
