how do disable policy that blocks NT 4.0 drivers for printers?

[Gillybob1]

I Have the same problem. I have just bought a new HP Deskjet 3630.

After installing the printer I found that I got the error in printers and scanner section of the control panel that the driver was unavailable. I tried to update the drivers only to find that the driver would not install because it was incompatible due to the policy that blocks NT 4.0 drivers.

I am running Windows 10 Pro which is all up to date with updates.

I have only bought this printer because my HP 2542 became incompatible with Windows 10.

Can you fix this problem or do I need to return the printer?

Hi,
Please follow the steps below to resolve such an error:

**Be aware that if you have other printers installed on your PC, those will need to be reinstalled too once completing these steps.

1. Uninstall the HP Software from your PC.
2. Backup your registry prior making any registry changes:
