Windows: How to extend evaluation period or convert to retail

When you download and install an evalution version of Windows, you are given 10 days before you have to activate Windows (Product key not required). After that you are given 180-days to evaluate it. You can extend the evaluation period three times. This gives you a total of 720 + 40 days for evaluation.

To display license information including remaining evalution time:
slmgr.vbs /dli

To display detailed license information including rearm count:
slmgr.vbs /dlv

To display expiration date:
slmgr.vbs /xpr

To rearm Windows (after evaluation has expired):
slmgr.vbs /rearm

To activate windows (after rearm you need to activate windows within 10 days):
slmgr.vbs /ato

TIP! If you like, you could schedule the rearm using Scheduled Tasks.

After evaluation period has ended you can convert the evaluation to a retail version (unless it is a Domain Controller).

To get the current edition of Windows:
dism /Online /Get-CurrentEdition

To convert from evaluation versions of Windows to retail versions:
dism /Online /Set-Edition: /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /AcceptEula

You can also use this to upgrade Windows to a higher edition. To get a list of editions you can upgrade to:
