Azure VM not activated..?


Technorati Tags:

encountered a strange issue that a new azure VM’s was not activating, this is suppose to happen “automagically”.


here is how I solved it:


1.Install the AVMA Key

Azure vm’s use the AVMA keys found at:

do not use a regular KMS Client Key, it wont work against

open a elevated CMD:
slmgr /ipk <AVMA_key>

2. Disable KMS host Caching 

cscript c:\windows\system32\slmgr.vbs /ckhc



3.Set the KMS host to cscript c:\windows\system32\slmgr.vbs /ato

cscript c:\windows\system32\slmgr.vbs /skms



4.Rerun Activation

cscript c:\windows\system32\slmgr.vbs /ato



SMACK! Activated 😉
