The new Windows 10 April 2018 Update was finally released, and if you are one of the lucky ones who immediately after the 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: Η εταιρεία προσφέρει έναν εύκολο τρόπο επαναφοράς στην προηγούμενη έκδοση των Windows από την εφαρμογή "Ρυθμίσεις".
Note that the reset option is only available unless you have deleted your previous Windows installation files. If you did this, you're on your own choice 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 procedure επαναφοράς, ξεκινήστε την εφαρμογή "Ρυθμίσεις" και από την ενότητα Ενημέρωση και better safety ανοίξτε το Ανάκτηση - Επιστρέψτε στην προηγούμενη έκδοση των Windows 10. Κάντε κλικ στο κουμπί Έναρξη για να ξεκινήσετε τη διαδικασία.
The previous version of the operating system was Windows 10 Fall Creators Update. The wizard will ask you to choose a reason to return to the previous version of Windows 10, which will probably help Microsoft know what it needs to improve in the future.
Before you begin the recovery, Windows 10 recommends that you check for updates, as the latest patches could help troubleshoot your issues. You can click No, and continue.
Windows 10 will guide you through the process, reminding you that you need to know the password to log in to your previous builds. In addition, the company states that you may need to reinstall some applications and that you will lose the changes you have made to the settings. Click Next and you will begin the recovery process.
Rolling back your system to the previous version of Windows 10 takes anywhere from 30 minutes to several hours. Don't do any restart on 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.
On your computers I did it I had no problem of course in the wizard I said everything not whenever no new future works so I have no problem
