Just seen a question about PowerShell v2. PowerShell v2 was a huge step forward when it appeared in October 2009 as part of Windows 7 / Server 2008 R2
Windows 7 support finishes 14 January 2020
Windows Server 2008 R2 support finishes 14 January 2020
That’s less than 6 months.
PowerShell v2 isn’t mentioned in the Microsoft documentation which starts at PowerShell v3
If you’re still using PowerShell v2 its beyond time to move to a later version.
