tidak bisa akses / connect printer windows 10 dari windows 7

That is completely normal. That specific registry subkey (PointAndPrint) often doesn't exist by default because Windows creates it only when policies are explicitly modified.

You can simply create it yourself. Here is how to add it:

Create the Missing Key

1. In the Registry Editor on the Windows 10 PC, navigate back to:
   
   
   Plaintext

   HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows NT\Printers
   

   (If the Printers key itself is missing under Windows NT, right-click Windows NT, select New > Key, and name it Printers).
   
   
2. Right-click the Printers key, select New > Key, and name it:
   
   
   Plaintext

   PointAndPrint
   

3. Click on the new PointAndPrint key.
   
   
4. Right-click in the empty space on the right side, select New > DWORD (32-bit) Value, and name it:
   
   
   Plaintext

   RestrictDriverInstallationToAdministrators
   

5. Double-click RestrictDriverInstallationToAdministrators and ensure its value data is set to 0.
   
   

Verification

• Check that RestrictDriverInstallationToAdministrators shows a value of 0 in the Data column.
  
  
• Restart the Print Spooler service in services.msc to apply the changes, then try connecting from Windows 7 again.
