We possess a new Win2008 R2 domain controller exactly where we're employing KMS but I'm obtaining problems including the KMS for Windows 7. I activated this server employing the MAK and after that utilized slmgr.vbs /ipk to install KMS keys. I was productive in incorporating keys for Win2008 R2 Enterprise and Win2008 Ent. I had trouble with adding the Workplace 2010 essential but located this article,Office 2010 Professional Key


which solved that issue. After putting in this I effectively additional my Workplace 2010 KMS crucial.
