This was the error message which greeted me, when I tired to update my Windows 10 laptop from the Anniversary update to the Creators Update, which was launched on April 11th.

But I was happy, and for a good reason. I had been trying to update the laptop using Windows Update for a few days, but it always failed and I got no error code. But when I downloaded the Windows 10 version 1703 ISO (Build 15063.138), and ran the update manually, I got the error code screeen which you see above.

In my case, the solution for this error was unique. You see, I use a recovery software called RollBack RX. It is kind of like system restore, but a much more reliable one. Having the Pro version of the software has its benefits, such as scheduled snapshots.I strongly suspected that RollBack RX, while a very useful program , could be the reason why the Windows Update was getting messed up, mainly because during the boot up process, the RollBack RX console runs, and this may have prevented the Windows bootloader,

Disclaimer: Geekiest and the author are not responsible for any data loss you incur. Proceed at your own risk. You will lose every snapshot you have taken when you uninstall the software.

Simply uninstall RollBack RX before you update to Windowds 10 creators Update or basically before any major Windows Update. Yes I know this may seem like a terrible solution, but I actually found this to be the only fix, right at HorizonDataSys forums. Those are the people who make RollBack RX.  This should work for both free and pro users of the software.

When uninstalling RollBack RX, you will be given the option to select the snapshot to uninstall to. Choose whichever one you want to, I chose the current one (i.e. the Windows which is running). You can then use the Explore option and select snapshtos, which may have data you want to migrate to the snapshot you selected. The uninstallation could take a while. Reboot after uninstalling RollBack RX, this is not mandatory, but just a precaution.  Now try updating the computer to the Windows 10 Creators Update. It should work perfectly, and now you can re-install RollBack RX safely.

For non-RollBack RX users who come across this error. I would recommend a simpler fix, trying to unplug USB devices and then starting the update. I did have an issue with an older version of Windows 10 which would get stuck on the logon screen, but when I unplugged my USB device, it would boot perfectly.
