Frequently Asked Questions

Why does my Windows taskbar show a browser icon for my PDF reader?

This occurs when Windows gets confused by file associations, usually after a web browser like Firefox or Microsoft Edge temporarily updates itself and attempts to take over as the default handler for opening PDF files.

Will reinstalling Adobe Acrobat fix the taskbar icon issue?

Yes, uninstalling and then reinstalling the software forces the Windows registry to completely rebuild the file associations and icon shortcuts from scratch, which often resolves stubborn display issues.

How do I manually change the icon of a pinned taskbar shortcut?

Right-click the pinned item on the taskbar, then right-click the application name in the pop-up list, and select 'Properties'. Under the 'Shortcut' tab, click 'Change Icon', browse for the correct application executable (.exe), select the proper icon, and click 'OK'.
