- If you can't see troubleshooters, click the Additional troubleshooters option on the right

- Here, find Windows update section

- Click Run the troubleshooter and wait till the process is finished.

Step 2

- Type Services in Windows search and hit Enter

- In the new Windows, scroll down till you find Background Intelligent Transfer Service (BITS)

- If the service is running, right-click and select Restart

- If not, right-click and select Start

Step 3

Press Win + REnter the following and hit Enter:

regsvr32 Qmgr.dll /s

Open the Run dialog again and run the following command:

regsvr32 Qmgrprxy.dll /s

Step 4

For this fix to work, you would have to find another Windows 10 machine of the same version (Home/Pro/Enterprise). If you have access to such a machine, do the following:

- Access another computerType regedit in Windows search and press Enter

- If User Account Control shows up, click YesNavigate to the following location:

HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Services\\TrustedInstaller

- Right-click on the branch and select Export

- Choose the location, name the file trustedinstaller and click Save

- Transfer the file to your computer

- Once the file is on your desktop, double-click the trustedinstaller.reg to merge it with your own registry

- Restart the PC and try updating Windows again.

Step 5

If none of the above helps, you can repair your Windows installation without losing files or installed apps. Here's how to do it:

- Go to the official Microsoft website and download installation files

https://www.microsoft.com/en-us/software-downlo...(press Download tool now)

- Once downloaded, double-click the setup.exe

- Accept License and Terms, select Upgrade this PC now, and click Next

- After the necessary files are downloaded, choose Keep personal files and apps

- Click Install (make sure that all apps are closed and not running before doing this)

- Your PC will restart and installation finished

Having the same issue.. Launching No Mans Sky through the Xbox (beta) app redirects me to 'Gaming Services' in the Microsoft Store which says that it's installed. Have tried uninstalling both with no joy. It has launched before from the Xbox app, but won't
now.

Hello BlackStar,

Let's try another method.

Please, install the Xbox PC app and launch the cloud games from there:

https://www.xbox.com/apps/xbox-app-for-pc

Select the Cloud Gaming tab and launch a game.

I've tried to install apps from Microsoft store like whatsapp and they have installed and launched perfectly fine but when trying to launch a game that was installed on the xbox app like dragon ball fighters z it pops up with the error code 0x803f8001.

The name of the bug report is "[Xbox Forum] Can anyone help me with my xbox app not installing/launching games?"

The submission date is 19/08/22.

Hi Samy,

I'm logged in correctly to the Xbox Console Companion. I can actually launch my games from there and play games as expected. However, when I launch the Xbox App from the Xbox Console Companion I am still not logged in to the Xbox App and cannot install new games or play games from the Xbox App.
