Intro
I have a lot of tasks related with the collecting of information about the virtual infrastructure. One of the steps of any audit is to get and analyze configuration compliance best practices. This stage always includes a manual check and BPA Analyzer for Hyper-V. BPA Analyzer became available in 2008 R2 (as a separate KB http://support.microsoft.com/kb/977238/en-us). But starting with Server 2012/2012 R2, BPA Hyper-V is already included in the RTM- version and can be run from the ” box “, using the Server Manager or module BestPractices. BPA Analyzer scans the Hyper-V role , including host configuration and virtual machines , and displays warnings about infractions of the best practices within the console and in the Server Manager. Obviously, If we have a large number of Hyper-V hosts, we need to automate this process. And,yes, automation=powershelling 
. Script is very simple. Tested on 2008 R2/2012.
TIP: This is not the last revision of this script. I will update post and script if I add some fixies or features. Please, follow me to receive any updates and feel free to write comments.
TIP: To succesfully run the script you shoud verify that ExecutionPolicy is RemoteSigned (Set-ExecutionPolicy -RemoteSigned) and PsRemoting is enabled on remote servers (Enable-PsRemoting).Usually, it’s not necessary.

Script performs..
1. Creates a folder C: \ BPA and C: \ BPA \ reports for storing reports and source data. If the folder Reports already exists , the process of creation is skipped.
2. Prompts you to enter a name NETBIOS-Hyper-V servers and stores the entered names in the file hvhosts.csv with the correct format
3. For each NETBIOS-name checks for installed Hyper-V role and starts scanning the BPA
4. Converts results (only warnings or errors) to the HTML-file (bpa/reports/bpa_servername.html) and automatically opens each report in browser
