The answer: Instead, it pins a browser instance with a special set of instructions embedded in a pinned shortcut file ( .lnk with extended properties) stored in a hidden user folder.
Chrome’s equivalent lives in:
This depends entirely on the browser’s : pin link to taskbar
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Taskband The binary Favorites and FavoritesResolve keys store a serialized list of AUMIDs and shortcut paths. Modifying these directly is not recommended—Windows will overwrite them. However, clearing these keys (after killing Explorer.exe) is the nuclear option to reset your entire taskbar. Pinning a File Link (file:// protocol) You can pin file://C:\report.pdf to the taskbar, but only if a registered application (your browser) can handle file:// . Dragging a PDF from File Explorer onto the taskbar pins the PDF viewer, not a link. Dragging a .url file (Internet Shortcut) from File Explorer works identically to dragging a URL from the browser. Network Shares (\server\share) Pinning a network path opens Explorer, not a browser. For a web-based network portal, the same browser-pinning rules apply. Third-Party Tools Tools like TaskbarPinner (open-source) or Pin More bypass Windows Shell APIs by directly writing to the Taskband registry binary data. They work but can corrupt the taskbar if the Windows version changes. Future: The Web as a First-Class Taskbar Citizen Microsoft is gradually merging PWA (Progressive Web App) installation with the taskbar pinning mechanism. In Windows 11 (23H2+), when you pin a link from Edge, Windows actually creates a hidden “Web App” package in:
$WshShell = New-Object -ComObject WScript.Shell $shortcut = $WshShell.CreateShortcut("$env:USERPROFILE\Desktop\MyPinnedLink.lnk") $shortcut.TargetPath = "C:\Program Files\Google\Chrome\Application\chrome.exe" $shortcut.Arguments = "--app=https://your-site.com" $shortcut.IconLocation = "C:\path\to\custom.ico,0" $shortcut.Save() Then drag that .lnk to the taskbar. The --app flag ensures Chrome treats it as an isolated window. Every pinned taskbar item is recorded in the Windows registry (per-user): The answer: Instead, it pins a browser instance
For true pinned-link isolation, always use the “Install as app” method, not drag-and-drop. Advanced: Manually Creating a Pin-Any-Link Shortcut You can force any URL or even a document to be pinnable by creating a custom .lnk file with the right properties using PowerShell:
%AppData%\Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar\ Examine that folder, and you'll see .lnk files. For a link pinned via Chrome, Edge, or Firefox, you’ll find a shortcut whose target is something like: However, clearing these keys (after killing Explorer
"C:\Program Files\Google\Chrome\Application\chrome.exe" --profile-directory=Default --app-id=cnkjkdjlofjkkkkehgcedagj Or in Edge:
