How to Prevent Pinning Programs to the Taskbar
Way 1: Disable Pinning Programs to the Taskbar with Local Group Policy Editor
Local Group Policy Editor can be used to change some computer settings and resolve issues. However, the Local Group Policy Editor is not available in the Windows Home version. If you are using the Professional, Enterprise, and Education editions, read the following steps to change settings.
Step 1: Press Win + R to open the Run window.
Step 2: Type gpedit.msc into the text box and hit Enter to open the window.
Step 3: Navigate to User Configuration > Administrative Templates > Start Menu and Taskbar.
Step 4: On the right pane, scroll down to find and double-click on the Do not allow pinning programs to the Taskbar policy.

Step 5: Select Enable in the prompt window and choose Apply > OK to confirm your choice.
Way 2: Permanently Unpinned Programs to the Taskbar Using Windows Registry
You can also tweak Registry Editor to change settings. But please be careful when you modify the registry keys. Windows Registry contains important information about computer software and firmware, which ensures the stable performance of your computer. Any changes you make in the Windows Registry will be directly implemented to your PC.
You can back up the registry key before you make changes. If, unfortunately, your computer encounters problems after changing, you can import the backup to revert to the previous status.
Step 1: Press Win + R and type regedit in the box.
Step 2: Press Enter to open the Registry Editor window.
Step 3: Shift to the HKEY_CURRENT_USER > SOFTWARE > Policies > Microsoft > Windows > Explorer.
Step 4: Right-click on the right pane and choose New > DWORD (32-bit) Value to create a new subkey.
Step 5: Rename this key as NoPinningToTaskbar.
Step 6: Double-click on the new subkey, change the Value data to 1 in the popup window, and click OK to save the change.

After these settings, you should restart your computer to fully apply the change. You can check whether you disable pinning programs to the taskbar successfully.
