Most of the companies use the activation of Windows and Office products in their Enterprise environment. The installation of KMS service is not so complicated , but when problems occur , it is possible many things, what could go wrong.
KMS key
By activating the KMS host to allow the volume license activation and reactivation within a corporate network. KMS clients are already installed in Windows with preloaded GVLK key ( Generic Volume License Key). Without this preloaded key you cannot activate a Windows using KMS key.
We cannot use KMS volume license on purchased computers that had pre-installed Windows Home Edition or Windows Ultimate or any other OS, for example Linux .
KMS service
You have 30 days to activate Windows and during this time it is in Out of Grace status . Upon successful activation, it checks the status every 7 days and must have access to the KMS host at least every 180 days Licence expires in 6 months. For example if someone is no longer in a firm, but he kept a business laptop , after 7 days of not reaching KMS host it enters in Out of Grace status , and every 2 hours trying to access the server . After 180 days, is no longer possible to use Windows.
To start the KMS service to operate automatically , it is necessary to activate 25 KMS Volume licenses manual.

For most of the errors with activation are purchased computers with the wrong OS – KMS keys can only be activated with a purchased Windows Professional . It is also possible that the BIOS uses ACPI_SLIC table . In these cases, the only solution is to use MAK license .
The other major problem, however, may represent a way to set the KMS host to activate Office 32 bit on Windows 64 bit because the script automatically takes the path of 64 bit Office .
