Here’s a quick one-liner in PowerShell to check the SharePoint patch level / build version.
(Get-SPFarm).BuildVersion
The output will be in table form and will include:
- Major (ex. 15)
- Minor (ex. 0)
- Build (ex. 5189)
- Revision (ex. 1000)
To reference the build number (for checking patch levels) you can use the following PowerShell one-liner:
((Get-SPFarm).BuildVersion).Build
Last one-liner to get all of the properties concatenated together (ex. 15.0.5189.1000):
(Get-SPFarm).BuildVersion -Join ‘.’
