Is it possible to revert back to my previous version of Windows after upgrading?

Yes, it is possible to revert back to your previous version of Windows after upgrading. Windows offers a built-in feature called "Go back to the previous version of Windows" that allows you to undo the upgrade. This feature is available for a limited time after upgrading, typically 10 days. To access it, go to Settings > Update & Security > Recovery, and under "Go back to the previous version of Windows 10," click on "Get started." This will initiate the rollback process, which may take some time to complete. It is important to note that rolling back will uninstall any applications and drivers installed after the upgrade, so it is advisable to backup important data before proceeding.
