This post is basically two questions...
1) In the database there is a table for the polling engines that notes the polling engine completion percentage, what percentage is considered good and at what point should I be concerned?
2) When I look at the polling engine table in the database, the Windows Version is not correct and changes just about every time I refresh the data, what is causing this?
Below are two screenshots of data from the polling engine table in the DB, as you can see when I refreshed the data the WindowsVersion changed.
