How to find out which SharePoint version am I using?

Sometimes it can be difficult to get the simplest information from SharePoint. Getting the SharePoint version is one of them. To find out what version of SharePoint are you using, go to server on which you installed your SharePoint and follow these steps:

1. Go to Registry: 

Press Win key on your keyboard + letter R.

This will open new window.

2. Write "regedit.exe" and press Enter key.

3. Now, go to the following path:

HKLM\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\14.0\WSS\InstalledProducts

It will look similar to this:

5. Now, you need to look at the GUID in the data column and match it to one of the following GUIDs and this is your version of SharePoint (GUIDs are different for 2010 and 2013 SharePoint versions).
