If you never use this feature, it can make the context menu feel cluttered, especially when you prefer a cleaner right-click experience.
Removing this option is usually done through a small Registry change, so it is best handled carefully. A quick backup before editing gives you an easy way to undo the change, and restarting File Explorer afterward helps Windows apply the update without requiring a full restart.
You can also restore “Cast to Device” later if you decide you need it again. The process is reversible, practical, and safe when you follow the steps in order and avoid changing unrelated Registry entries.
What the “Cast to Device” Context Menu Option Does
The “Cast to Device” entry in the Windows 10 right-click context menu is a built-in media streaming shortcut. It appears when you right-click supported media files such as photos, music, and videos, and it lets you send that content to compatible devices on your local network. Typical targets include smart TVs, Xbox consoles, wireless speakers, media receivers, and other DLNA or Miracast-capable devices that Windows can detect.

For example, if you right-click an MP4 video, a JPEG image, or an MP3 audio file, Windows may show Cast to Device as one of the available actions. Selecting it opens a small casting window where you can choose a detected playback device. Windows then attempts to stream the selected file over the network, allowing the other device to play the content without manually copying the file to a USB drive or shared folder.
This feature is separate from basic file sharing and is also different from projecting your entire screen. Cast to Device is mainly designed for sending individual media files to another device for playback. Screen projection, by contrast, mirrors or extends your desktop. Network file sharing gives another computer access to files and folders. Because these features overlap in some home setups, the context menu item can feel unnecessary if you never stream media directly from File Explorer.
Many users remove this option simply to make the right-click menu cleaner and faster to scan. It can be especially annoying on systems where the menu already contains entries from cloud storage tools, compression utilities, antivirus software, graphics drivers, and media apps. Removing Cast to Device does not delete your media files, uninstall Windows Media Player, disable your network adapter, or stop all wireless display features. It only hides that specific shell extension from the File Explorer context menu.
Before You Begin: Create a Registry Backup
Before removing the “Cast to Device” entry from the Windows 10 context menu, create a backup of the Registry keys you plan to change. The Registry stores low-level Windows configuration, and even a small edit in the wrong location can affect system behavior, File Explorer, or installed apps. A backup gives you a quick way to undo the change if the menu entry does not disappear as expected or if you decide to restore the feature later.
For this task, you do not need to back up the entire Registry unless you want an extra layer of protection. Exporting the specific key you will edit is usually enough and is easier to restore. You can also create a System Restore point before making changes, especially on a work PC or a computer with software settings. A Registry export restores selected Registry values, while a System Restore point can roll back broader system configuration changes.
Create a Registry backup for the relevant key
- Press Windows + R to open the Run dialog.
- Type regedit, then select OK.
- If the User Account Control prompt appears, select Yes.
- In Registry Editor, use the address bar or left pane to navigate to the key you will edit in the next section. For the common “Cast to Device” context menu handler, this is usually: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions.
- Right-click Shell Extensions in the left pane and choose Export.
- Choose a safe location, such as your Desktop or Documents folder.
- Give the file a clear name, such as shell-extensions-backup.reg.
- Make sure Selected branch is chosen under Export range, then select Save.
The exported .reg file contains the Registry data from that branch at the time you saved it. Keep it until you have confirmed that the context menu looks and behaves the way you want. If you are managing several computers, save the file with the PC name and date in the filename so you can identify it later, for example office-pc-shell-extensions-2026-05-27.reg.
Create a System Restore point as an added safeguard
- Open the Start menu and search for Create a restore point.
- Select the matching result to open the System Properties window.
- Under Protection Settings, select your system drive, usually C:.
- If protection is off, select Configure, enable system protection, and choose an appropriate disk space limit.
- Select Create, enter a description such as Before removing Cast to Device, and select Create again.
After the backup is complete, you can proceed with the Registry change more safely. If anything goes wrong, you can restore the exported Registry branch by double-clicking the saved .reg file and confirming the prompts. For broader problems, use System Restore from the same System Properties area to return Windows to the restore point you created.
Remove “Cast to Device” Using Registry Editor
After backing up the relevant Registry keys, you can remove the Cast to Device entry by disabling the shell extension that adds it to the right-click menu. In Windows 10, this option is commonly tied to a shell extension with the CLSID {7AD84985-87B4-4a16-BE58-8B72A5B390F7}. The safest practical approach is to create a Blocked entry for that CLSID under Shell Extensions, rather than deleting system keys outright.
Do these 3 things before closing this tab:

If the User Account Control prompt appears, choose Yes. In Registry Editor, use the left pane to navigate to this location:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions
Rank #2
- Fresh USB Install With Key code Included
- 24/7 Tech Support from expert Technician
- Top product with Great Reviews
If you do not see a key named Blocked under Shell Extensions, create it. Right-click Shell Extensions, select New > Key, and name the new key Blocked. Make sure the spelling is exact, with no extra spaces.
- Select the Blocked key.
- Right-click in the empty area on the right side of Registry Editor.
- Select New > String Value.
- Name the new string value {7AD84985-87B4-4a16-BE58-8B72A5B390F7}.
- Leave its value data blank; you only need the string value name.
When finished, the full Registry path should look like this:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions\Blocked
And inside the Blocked key, you should see a string value named {7AD84985-87B4-4a16-BE58-8B72A5B390F7}. This tells Windows not to load the shell extension responsible for showing Cast to Device in supported context menus, such as when right-clicking media files or folders containing media.
On some Windows 10 installations, especially where per-user shell extension settings are involved, you may also apply the same change under the current user Registry hive. To do that, navigate to:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions
Create a Blocked key there if it does not already exist, then add the same string value named {7AD84985-87B4-4a16-BE58-8B72A5B390F7}. This user-level entry can be useful if the option remains visible for your account after changing the machine-wide setting.
Avoid deleting the original CLSID key from other Registry locations. Blocking the extension is easier to reverse, less likely to affect unrelated Windows components, and better suited to routine customization. Once the string value is in place, close Registry Editor. The change may not appear immediately in File Explorer until Explorer is restarted or you sign out and back in.
Restart File Explorer to Apply the Change
After removing the Cast to Device context menu entry in Registry Editor, Windows may not update the right-click menu immediately. The context menu is handled by File Explorer, so you usually need to restart the Explorer process before the change becomes visible. This is faster and more convenient than restarting the entire computer, and it does not undo your Registry edit.
The safest practical way to do this is through Task Manager. Restarting File Explorer may briefly hide your desktop icons, taskbar, and open File Explorer windows. They should return automatically within a few seconds. Save any work in open folders or file operations before continuing, especially if you are copying, moving, renaming, or deleting files.

Once File Explorer has restarted, test the change by right-clicking a supported file type such as a picture, video, or music file. The Cast to Device option should no longer appear in the context menu. You can also test by right-clicking inside File Explorer after selecting a media file, since this is where the entry is most commonly shown.
If you do not see Windows Explorer listed in Task Manager, open any folder first, then check Task Manager again. You can also restart Explorer by ending the process and starting it manually, but the built-in Restart button is cleaner and reduces the chance of leaving the desktop temporarily unavailable.
Alternative: Sign Out or Restart Windows
If restarting File Explorer does not refresh the context menu, sign out of your Windows account and sign back in. This reloads the user shell and related context menu handlers. A full restart also works and is useful if you have made several Registry changes or if Explorer does not reload correctly.
- Restart Explorer: Best first option; quick and usually enough.
- Sign out and sign back in: Useful when the menu still shows the old entry.
- Restart the PC: Best if Explorer behaves unusually or the Registry change does not appear to apply.
After the refresh, the removal should remain in place for your current Windows installation. If the option returns later, it may have been restored by a system update, a media feature component, or a Registry file that re-added the deleted key. In that case, repeat the Registry check and restart File Explorer again.
Restore “Cast to Device” to the Context Menu
If you removed the Cast to Device entry and later want it back, you can restore it by reversing the Registry change. The exact method depends on how you removed it: by importing a backup, deleting a blocking value, or recreating the original Registry key. In most cases, the safest approach is to use the Registry backup you created before making changes.
Restore from your Registry backup
If you exported the affected Registry key before editing it, locate the saved .reg file, right-click it, and choose Merge. When Windows asks for confirmation, select Yes, then choose OK after the values have been added back to the Registry. This restores the saved Registry data to the state it was in before you removed the context menu entry.
After merging the backup, restart File Explorer so the context menu refreshes. Press Ctrl + Shift + Esc to open Task Manager, find Windows Explorer under the Processes tab, select it, and click Restart. You can also sign out and sign back in, or restart the PC if the option does not appear immediately.
Remove the blocking value manually
If you removed Cast to Device by adding a blocking string value under the Blocked shell extensions key, you can restore the menu item by deleting that value. Open Registry Editor and go to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions\Blocked
In the right pane, look for the string value named:
Rank #4
- Repair boot manager is missing, NTLDR is missing
- Blue Screens of Death (BSOD) and more,Works on any make or model computer, as long as you have a valid product key to install
- This item does not include a key code or a license. You must have your own key code to use the install option.
{7AD84985-87B4-4a16-BE58-8B72A5B390F7}
Right-click that value and select Delete, then confirm the deletion. This removes the block that prevents the Cast to Device shell extension from loading in the right-click menu. Restart Windows Explorer afterward to apply the change.
Recreate the Cast to Device handler if it was deleted
If the original shell extension key was deleted instead of blocked, restoring it from your backup is preferred. If no backup is available, you may need to recreate the handler entry manually. The commonly used handler location is:
The Tool Desk
Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers\PlayTo
The default value for the PlayTo key should point to the Cast to Device shell extension CLSID:
{7AD84985-87B4-4a16-BE58-8B72A5B390F7}
- Open Registry Editor as an administrator.
- Navigate to HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers.
- If PlayTo is missing, right-click ContextMenuHandlers, choose New > Key, and name it PlayTo.
- Select the PlayTo key, double-click (Default) in the right pane, and set its value to {7AD84985-87B4-4a16-BE58-8B72A5B390F7}.
- Close Registry Editor and restart Windows Explorer.
Once restored, right-click a supported media file such as a photo, video, or music file and check whether Cast to Device appears again. The option may not show for every file type, so test with common formats such as .jpg, .mp4, or .mp3. If it still does not return, restart Windows and confirm that network discovery and media streaming features have not been disabled separately.

If Cast to Device still appears after editing the Registry and restarting File Explorer, first confirm that the change was made in the correct location. Open Registry Editor again and check the key you modified, especially if you removed or renamed the handler under Shell Extensions. A small typo in the key name, an edit made under the wrong hive, or a value placed in the wrong subkey can leave the menu item untouched.

Check the Registry path and value
For the common blocking method, go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions\Blocked. Make sure the Blocked key exists and that it contains the string value for the Cast to Device shell extension. The value name should be:
{7ad84985-87b4-4a16-be58-8b72a5b390f7}
The value data can be left blank. If you created the entry under HKEY_CURRENT_USER instead, or placed it inside a similarly named but incorrect folder, Windows may continue loading the extension. After correcting the entry, close Registry Editor and restart File Explorer again from Task Manager.
Restart Explorer or sign out completely
Restarting Windows Explorer is usually enough, but cached shell extensions can sometimes remain visible until the user session is refreshed. If the item still appears, save your work, sign out of Windows, and sign back in. If that does not work, restart the PC. A full restart reloads the shell and clears context menu handlers that may have stayed active in memory.
- Restart Explorer: Open Task Manager, select Windows Explorer, then choose Restart.
- Sign out: Open the Start menu, select your account icon, then choose Sign out.
- Restart Windows: Use this if Explorer restarts do not refresh the menu.
Test different file types and locations
The context menu in Windows 10 can vary depending on what you right-click. Test the change on a local media file such as an MP4, MP3, JPG, or PNG stored in a normal folder like Documents or Pictures. Avoid testing only inside libraries, network locations, OneDrive placeholders, or search results, because those views can show slightly different shell behavior. Also check both the desktop right-click menu and file right-click menus, since the option may not be exposed in every context in the same way.

Look for third-party media or device software
If the built-in Windows entry has been removed but a similar casting option remains, it may be coming from another application. Media servers, TV companion tools, phone utilities, graphics drivers, and streaming apps can add their own right-click commands. Review recently installed software and disable its shell integration from within the app settings if available. Tools such as Microsoft Sysinternals Autoruns can also show shell extensions, but use them carefully and disable only entries you recognize.
If none of these checks remove the item, restore the Registry backup you created earlier and repeat the process from the beginning. Work slowly, verify the exact key and GUID, then restart Explorer or reboot. This approach keeps the change reversible while helping you avoid removing unrelated context menu handlers.
Frequently Asked Questions
Is it safe to remove “Cast to Device” from the Windows 10 context menu?
Yes, it is safe if you only remove or rename the specific Registry entry related to the “Cast to Device” shell extension. This change does not uninstall media streaming features or delete your files. Create a Registry backup first so you can restore the menu option if something does not work as expected.
Will removing “Cast to Device” stop casting from apps like Movies & TV or Microsoft Edge?
Removing the context menu entry only hides the right-click shortcut in File Explorer. It usually does not disable casting features inside supported apps. You may still be able to cast media through app menus, device settings, or other Windows media streaming options.
Do I need to restart my computer after changing the Registry?
In most cases, you do not need a full restart. Restarting Windows Explorer from Task Manager is usually enough to refresh the right-click menu. If the option still appears after restarting Explorer, sign out and back in or reboot the PC.
How do I restore “Cast to Device” if I want it back later?
If you exported a Registry backup before making changes, double-click the saved .reg file and confirm the prompts to restore it. Then restart File Explorer or reboot Windows. If you renamed a Registry key instead of deleting it, change the name back to its original value.
Why does “Cast to Device” still show after I edited the Registry?
The change may not have loaded yet, so restart File Explorer or reboot the computer. Also check that you edited the correct Registry location and did not accidentally change a similarly named entry. If you use mulle Windows user accounts, confirm the change applies where you expect it to appear.
Bottom Line
Removing “Cast to Device” from the Windows 10 context menu is straightforward when you use the Registry carefully: back up the key first, make the small edit, then restart File Explorer to apply the change. This keeps the right-click menu cleaner without uninstalling media features or making broad system changes.
