If the prompt "Your Windows license will expire soon" pops up as shown in the below screenshot, here are some steps to take.
To resolve this issue, there are two ways
1. You will need to destroy and re-allocate the lab VM's to get to the new nodes about 5 times.
2. Here is the issue, anytime when you create a new Windows Image in AWS, you will need to run the below command to make sure it will be pointed to AccelerEd's KMS server to activate. This is while during the image creation.
Or you can as well run the command from a PowerShell window, opened with "Run as Administrator" inside the Windows VM.
C:\ProgramData\Amazon\EC2-Windows\Launch\Scripts\InitializeInstance.ps1; cscript "${env:SYSTEMROOT}\system32\slmgr.vbs" /ato
This should fix the issue.
