I was experimenting with ConvertTo-CSV command that is supported by powershell < 3.

It could be used to support Windows 7 users.
It sounds weird, but there is still an important group of people that still uses Windows 7.
However, the output is not good at all: It's more like a string, from which we need to extract data using either a regular expression or a substring logic (easier).

What's your thoughts on this?
The output could depend on the way the certificate was created (which options were provided during creation), but it could be an attempt to support more users before bypassing verification.
Or even try a verification without any nice error handling for these users.

Why not just check windows version? Got it. If user will upgrade to new version on win 7.
