Microsoft gave a few pointers on how you can manage to uninstall Windows 8.1, depending on what type of installation you did, and the two solutions will be presented as plainly as we can, so you can accomplish this with the least amount of effort.
Method 1: If you upgraded for free from Windows 8
If you already have Windows 8 installed on your device, then you most likely upgraded to Windows 8.1 with the free patch (link below).
If this is how you installed it, then uninstalling Windows 8.1 is as simple as doing a System Restore or a System Refresh (Settings->Change PC Settings->General->Refresh or Restore). Keep in mind that you will need a bootable Windows 8 disk, either a DVD or a memory stick to do this.
Method 2: If you did a clean install from older versions of Windows
On the other hand, if you went all the way from Windows XP, Vista or 7 to Windows 8.1, the process will take a while longer and there will be some data loss. Basically, in this scenario, in order to uninstall Windows 8.1, you will need to format and reinstall your old operating system.
