A preface

Judging the operating system version, is an old topic, bat, VBS, there are examples, this is not an important issue, I feel not worth writing posts.
But pinch, with the win version of the increase, PowerShell version fragmentation more and more serious, so "use PowerShell to determine the operating system version"
It's getting more and more important. In other words, you must determine the operating system version before using a slightly biased PowerShell command. Or, strongly
We recommend that you use the latest version of the win server, the win client to play PowerShell.

Advantages and disadvantages of the two methods

Cmd+ver Method:
There seems to be no server or client.

WMI Method:
Recommended

SystemInfo Method:
There is a difference between the command of the Chinese system and the English system.
