Look at this, https://fileinfo.com/extension/dll What programs have you installed or use that require them? Have you ever deleted any of them?

Hi Tony Platt,

Additionally, I would suggest checking whether the underlying Windows component files are damaged.

Open Terminal/Command Prompt as Administrator.
Run: DISM /Online /Cleanup-Image /RestoreHealth
Then run: sfc /scannow
Restart the PC and check whether the Game Bar DLL errors return.

If both commands complete successfully but the same DLL errors continue, please share your Windows version and OS build (Win + R > winver) along with the exact error message or a screenshot. That will help narrow this down without repeating the steps you have already tried.

I hope this helps isolate the cause.

For this gaming/Xbox scenario, the supported fixes are:

Restart Windows first. Some Gaming Services sign-in and launch issues are caused by a bad service state, and a restart can clear that.
Reinstall Gaming Services.
- Open PowerShell as Administrator.
- Run:
```
     get-appxpackage Microsoft.GamingServices | remove-AppxPackage -allusers
```
- In the same PowerShell window, run:
```
     start ms-windows-store://pdp/?productid=9MWPM2CQNLHN
```
- Install Gaming Services from that Store page, accept the UAC prompt, and then try launching the game again.
If the Xbox app is also failing, update or reinstall the Xbox app.
- Make sure the PC is in the RETAIL sandbox.
- Open PowerShell as Administrator.
- Run:
```
     get-appxpackage Microsoft.XboxApp | remove-AppxPackage -allusers
```
- Then run:
```
     start ms-windows-store://pdp/?productid=9mv0b5hzvk9z
```
- Install the Xbox app again from the Store.
If Gaming Services install/start errors appear, use the Microsoft support workaround for Gaming Services corruption.
- Open Notepad.
- Paste this PowerShell script:
```
     Get-AppxPackage *gamingservices* -allusers | remove-appxpackage -allusers
     Remove-Item -Path "HKLM:\System\CurrentControlSet\Services\GamingServices" -recurse
     Remove-Item -Path "HKLM:\System\CurrentControlSet\Services\GamingServicesNet" -recurse
```
- Save it as RepairGamingServices.ps1 with Save as type = All Files (.).
- Right-click the script and select Run as administrator.
- Restart the device.
- Start the Xbox app and install Gaming Services again when prompted.
If the problem started around Xbox/Game Pass game launching, install the Windows update listed for Gaming Services issues on Windows 10: KB5004476.
If the errors are specifically about missing DLLs when launching an app, reinstalling the relevant Microsoft Visual C++ components is the documented fix for missing runtime DLL conditions.

Note: the Gaming Services repair script removes service registry keys and reinstalls the component. Use it only as written, then restart before testing again.
