You may be wondering why you cannot get Windows Update to download and install the Threshold 2 update.
One reason may be that you need to wait your turn as there are more than 100 million computers that need to be updated from the initial release (build 10240 Windows Version 10.0) to Threshold 2 (build 10585 Windows Version 1511).
The second reason may be due to the fact that you upgraded from Windows 7 or 8.1 less than 30 days ago. To preserve your ability to go back (Restore your previous version of Windows) to Windows 7 or 8.1 Microsoft is holding back the update to give you the full 30 days just in case you want to go back to your earlier version of Windows.
Once the Threshold 2 update is installed you will lose the ability to go back to 7 or 8.1 and the only version you can go back to would be the initial release of Windows 10 (build 10240) as there is no “double rollback” option.
There is a means of preserving the ability to go back in this Wiki article: How to extend the 30 day limit to go back to your previous version of Windows

if you have not performed the steps mention in the Wiki article mentioned earlier.
4) As always, if you can make an Image Backup of Windows 10 before you upgrade, the backup will allow you to restore Windows 10 should something go wrong during or after the upgrade has completed.
After the upgrade has completed in the search box enter: winver.exe and click on the ‘run command’ option at the top of the list. This will display the current version of Windows 10 that is installed on your computer.
