Answer 1

Hi,
1.I want to downgrade my windows from 2004 to 1909 i want to know if it has any downsides of doing so
What you need to know before you go back

It will keep your documents, photos, and other personal files, but it can't save:
• Any apps installed after the most recent upgrade
• Any changes to personal settings made after the upgrade
• If you're using a local account, you'll need to sign in to this PC with your old password after going back. This doesn't apply to a Microsoft account.
• If you go back to Windows 8.1, some apps that came with Windows, like Mail and People, might not work anymore. To fix them, reinstall them from the Store.
• If you’re a Windows 10 Insider with a Windows 10 preview build installed, going back to an earlier build won’t remove you from the Insider Program. When the next preview build is ready, it'll be installed on your PC.

It depends on the activation status of your current computer.
