Answer 1

Run Get-SPProduct on your command line. If you are listed with multiple products, then use the index for the commands mentioned in the blog. Eg:

PS C:\> $spprod = Get-SPProduct
[If listed with more than one product]
PS C:\> $spprod[0].Servers | select ServerName, Products, InstallStatus

 $spprod[0].Servers | ? { $_.InstallStatus -eq "InstallRequired" } | % { $_.RequiredButMissingPatches }
