When you use Default Apps or Open With to associate .PDF files with Adobe Reader or any other app, nothing may happen. In some cases, the association will change for a brief time, and then it will revert to Microsoft Edge as the default.<\/p>\n

Possible Cause<\/h2>\n

In recent builds of Windows 10 and 11, the .PDF association registry key (i.e., “.PDF\\UserChoice<\/code>“) registry key is protected by the User Choice Protection Driver (UCPD.sys).<\/p>\n

However, the UCPD driver is not supposed to stop you from changing the file associations via Open With or Default Apps. It’s unknown why the association change is blocked.<\/p>\n

RELATED:<\/strong> Change Default Apps and File Association via Command-line<\/a><\/div>\n

Workaround<\/h2>\n

Disable the UCPD driver and its scheduled task. To do so, run these commands from an admin Command Prompt:<\/p>\n

sc.exe config UCPD start= disabled\n\nschtasks.exe \/change \/Disable \/TN \"\\Microsoft\\Windows\\AppxDeploymentClient\\UCPD velocity\"<\/pre>\n
Restart Windows.<\/strong><\/p>\n
Open Task Manager and end all instances of msedge.exe<\/code>.<\/p>\n
Alternatively, you can run the following command to kill all msedge.exe instances.<\/p>\n
taskkill \/im msedge.exe \/f<\/pre>\n
\"taskkill<\/p>\n
Now,\u00a0see if you can change PDF associations via Default Apps or Open With.<\/p>\n
