If you have already enrolled in the Windows Insider Preview program and want to opt-out of the same, here is a step-by-step guide to doing so.
Step 1: Open the Settings app on your Windows 10 computer. For this, press the Windows + I keys on your PC.
Step 2: In the Settings app, click on the “Update & Security” option.
Step 3: Now, click on the “Windows Insider Program” option.
Step 4: There, toggle off the switch for the “Step getting preview builds” option.
Step 5: Your system may ask to restart the device. In that case, click on the “Restart Now” button to continue.
Once these steps are completed, the final version of the Windows 10 operating system will be installed on your computer and then you will be opted out of the Insider Preview program but you will continue to get the security and non-security updates.
