How to install a remotely connected printer after KB5005565

I need to figure out how to connect to and use shared printers connected (by USB) to a remote PC in my office.

Now, before you send me to this tutorial here:
Add Shared Printer in Windows 10
please note that this method of installing the printer, which is technically called "Point And Print", is broken after the installation of Windows Update for 21H1 KB5005565. There is a security exploit in Point And Print that is being closed.

The update breaks the connection for this particular configuration: Printer connected to Computer A with USB, remote clients connect and print through Computer A.
The security fix does not seem to affect connecting to remote wireless printers, or printers connected with Ethernet to the router.
More on this problem here: Possible printer issue with KB5005565

I believe that I will need to install the printer drivers on each client PC before they can access and use the printers on Computer A.
That , in itself, will be a challenge since one of these is an old printer and the driver software is not compatible with Windows 10.

What I'm trying to figure out (in advance) is how do I do it? And once I get drivers installed on each remote PC, what would be the procedure to "Add A Printer" from the Host PC afterward?

Just trying to plan ahead. I can always do trial and error.

The reason I believe I will need to do this method is contained in this KB article from Microsoft here:
https://support.microsoft.com/en-us/...b-6d8e9a302872

I have uninstalled KB5005565 and everything is working fine again. I have paused updates but that is just a temporary workaround. I would rather not override the security with the registry hack. I want to find a way to get this particular configuration to work after installing KB5005565.

When you connect to a remote printer windows downloads he drivers from the pc assuming it has the right ones

Hi Samuria

Unfortunately, that's how it used to work. Now (after KB5005565) the remote PC does not have permission to access the driver from the host PC. Either nothing happens or the access fails with error code 0x0000011b.
And you can't "Add A Printer" from the remote host PC without the same error.
Uninstalling KB5005565 solves the problem.

Thus the question.

Here is the notice from Microsoft regarding the change that is causing my (and some others) problem:

Point and Print Default Behavior Change

MSRC / By MSRC Team / August 10, 2021

Our investigation into several vulnerabilities collectively referred to as “PrintNightmare” has determined that the default behavior of Point and Print does not provide customers with the level of security required to protect against potential attacks.
Today, we are addressing this risk by changing the default Point and Print driver installation and update behavior to require administrator privileges. The installation of this update with default settings will mitigate the publicly documented vulnerabilities in the Windows Print Spooler service. This change will take effect with the installation of the security updates released on August 10, 2021 for all supported versions of Windows, and is documented as CVE-2021-34481.

This change may impact Windows print clients in scenarios where non-elevated users were previously able to add or update printers. However, we strongly believe that the security risk justifies this change. While not recommended, customers can manually disable this mitigation with a registry key, which is outlined in the following KB Article:
KB5005652 How to manage new Point and Print default driver installation behavior

Disabling this mitigation will expose your environment to the publicly known vulnerabilities in the Windows Print Spooler service and we recommend administrators assess their security needs before assuming this risk.

As always, we recommend customers install all security updates as soon as possible. More details on all updates can be found in the Microsoft Security Update Guide. Customers who have automatic updates enabled are automatically protected.

So perhaps I am asking the wrong question.

How do I give my remote clients "Administrator Privileges" to access drivers on the host with KB5005565?
How can the remote client be given an "elevated user" status?

One of our members found a workaround for this problem.
Making this registry change will allow remote client PCs to print to printers connected to a host PC by USB cables with KB5005565 installed on the host PC.
