    Where can I find my product key? Also, what is PowerShell and why does this window pop up at log on. Do I need this headache?

    Hi Rick Wright

    To better understand your situation, may I kindly clarify the following:  What is the subscription tier of the affected account? 

    For general context related to product keys, you may refer to the following document: Using product keys with Microsoft 365 | Microsoft Support  

    In addition, if you are using a volume licensed version of Office Professional Plus at your workplace, you would typically need to contact your administrator to obtain the product key. 

    I hope this provides additional insight.
