It is not possible to modify the width of "GPO Name" and "GPO Domain" in the Link window. All other columns do resize properly.
To reproduce:
1. Right-click the registered policy, select "Link"
2. Put check mark on any OU, Domain or Size.
3. Try resizing "GPO Name" and "GPO Domain". All other columns resize correctly.
This is working as designed. The GPO Name and GPO Domain columns are set to fill the available space when the dialogue is resized. Due to the nature of the view, this means that they share the available space, while other columns do not attempt to fill space. Thus, as the GPO Name column is made larger, the GPO Domain column will shrink and vice versa. Changing this to work differently results in blank unused space when the dialog is made larger. This is a compromise behaviour we believe gives the best available experience.
