Article
09/07/2011

Another little powershell script to automate some bits that i come across

this script will

1. test if you have the hyper-v bpa installed

2. download the hyper-v and install it

3. run it and list errors and warnings

4. output the whole thing to a CSV file

this is on the start of the script i have a bit more the add so will be posting more at a later date

#script begin
