I can't install games in xbox app even I have extra disk space.

No worries Ali, in any case, I'll be here if you need me.

Cheers.

I have two questions :
1- If I reset Xbox app, does it cause all my games delete?
2- If I reset Microsoft Store app, does it cause all my apps and games delete?

I see. Ali, for now, the game pass app doesn't allow us to choose exactly where we want to install games as of yet, that procedure I sent you is a possible workaround that, in some cases, help, but is not a definitive fix.

But, there's good news hehe, the game pass app on windows is about to get an update that will change that, it will give us the freedom to install the games wherever we want, also, will give us full access to its files. The update has no official date yet but will come soon we believe.

Try to do a clean boot on your PC and then try again mate.

Right-click the Start button.
Click Search.
Type msconfig and hit Enter on your keyboard.
Click Services.
Click the checkbox next to Hide all Microsoft services.
Click Disable all.
Click Startup.
Click Open Task Manager.
Click any startup program you suspect might be interfering.
Click Disable. Repeat steps 9 and 10 for all startup programs.
Click the X to close Task Manager.
Click OK in the System Configuration window.
Restart your PC.

I've tried everything(all of your steps), but I couldn't change the name

Hello dear Gamer, first it's a pleasure to be able to help you today.

My name is Vinicius.

Hey AliEmir1, how are you today? Hope you're well.

Open Settings on Windows 10.

Click on System.

Click on Storage.

Under the “More storage settings” section, click the Change where new content is saved option.

Use the New apps will save to drop-down menus to select the new default location for apps.

Click the Apply button.

If that doesn't work, or any error like this: 0x80070005 appears:

1. Go to "my computer" > Select the disk you want to save files from now on.

2. There will be a folder called "Windows apps" > Right click and select properties > security > advanced.

3. Another tab will appear, click continue (for this, your account must have admin privileges).

4. Where is owner click "change" > then "Advanced" > Then "find now" > Then choose "Authenticated Users" > Click OK, then OK again and click apply.

5. After this rename the WindowsApps folder to WindowsApps.old

6. Create a new folder called WindowsApps.

NOTE: It is important that you rename the folder according to step 5 and create another one according to step 6, otherwise it won't work.

7. Restart the PC.

8. Then try changing the save location for new apps and games in the settings again.

9. If it still doesn't work for you, delete the WpSystem folder on your D drive: it should allow you to change download locations without an error

Now I realized my xbox download folder has changed when I join Windows Gaming. The time I quit Windows Gaming, I deleted the XboxGames file too, and xbox app is trying to install games to XboxGames file. I created again the file(The issue which I couldn't click download is solved) but it is empty, and I'm having an issue downloading it gives the error 0x00000001.
