The new Windows 10 April 2018 Update was finally released, and if you are one of the lucky ones immediately after installation the problems started below we will see how you can go back to the previous version.
The Windows 10 April 2018 Update, also known as the 1803 version, is expected to be automatically available on the first wave of systems through Windows Update from tomorrow, May 8th. 
Microsoft uses this gradual release in every major update, as it tends to collect information from the systems that install it. It then deals with the errors that occur before it becomes available on more than one device.
But with so many bugs discovered in the last few days, Microsoft will definitely need some time to fix all the bugs. So going back to an older but more functional version of Windows is not a shame. It also happens in the best families.
Let's see how it works:
Microsoft has thought of you: The company offers an easy way to restore the previous version of Windows from the "Settings" application.
Note that the reset option is only available unless you have deleted your previous Windows installation files. If you did this, your only option to go back to the previous version of Windows is to install it from scratch and start from scratch.
Windows 10 April 2018: To start the recovery process, start the "Settings" application and from the Update and Security section, open Recovery - Go back to the previous version of Windows 10. Click the Start button to start the process.
The previous version of the operating system was Windows 10 Fall Creators Update. The guide it will ask you to choose a reason for going back to the previous version of Windows 10, which should probably help Microsoft know what to improve in the future.
Before starting with recovery, Windows 10 recommends checking for updates, as the latest patches could help address the issues you are experiencing. You can click No, and continue.
Windows 10 will guide you through the process, reminding you that you will need to know the password access για να συνδεθείτε στα προηγούμενα build σας. Επιπλέον η εταιρεία αναφέρει ότι ίσως χρειαστεί να εγκαταστήσετε ξανά κάποιες εφαρμογές αλλά και ότι θα χάσετε τις αλλαγές που έχετε κάνει στις ρυθμίσεις. Κάντε κλικ στο κουμπί Επόμενο και θα ξεκινήστε με τη διαδικασία recoverys.
Restoring your system to the previous version of Windows 10 takes from 30 minutes to several hours. Do not restart your computer until the process is complete.
Once the recovery is complete, your system will restart one last time before you see the desktop of the previous version of Windows 10.
