Here's how to Fix Cannot change default app by File Type in Windows.

There are a few things you can try if you are unable to change the default app by file type in Windows:

1. **Make sure that you are an administrator.** Only administrators can change the default app for a file type. To check if you are an administrator, open the Start menu and type "Control Panel." Click on "Control Panel" and then click on "User Accounts." Under "User Accounts," click on "Change User Account Control settings." Make sure that the "Use User Account Control (UAC) to control when apps start and interact with your computer" slider is set to "On."
2. **Restart your computer.** Sometimes, a simple restart can fix problems with Windows. To restart your computer, press the `Windows`+`R` keys on your keyboard. Type "shutdown /r" and then press `Enter`.
3. **Run the Windows Update troubleshooter.** This tool can automatically identify and fix problems that are preventing Windows from working properly. To run the troubleshooter, open the Start menu and type "troubleshooting." Click on "Troubleshoot settings" and then click on "Additional troubleshooters." Under "Get up and running," click on "Windows Update" and then click on "Run the troubleshooter."
4. **Reset the Windows Update components.** This can sometimes fix problems with Windows Update that are caused by corrupted or outdated components. To reset the Windows Update components, open an elevated command prompt and run the following commands:

```
net stop wuauserv
net stop cryptsvc
net stop bits
net stop msiserver

Ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
Ren C:\Windows\System32\catroot2 Catroot2.old

net start wuauserv
net start cryptsvc
net start bits
net start msiserver
```

5. **Disable your antivirus software.** Sometimes, antivirus software can interfere with Windows Update. To temporarily disable your antivirus software, open your antivirus program's settings and disable it. Once you have disabled your antivirus software, try installing the Windows Update again.
6. **Try installing the Windows Update in Safe Mode.** Safe Mode is a diagnostic mode that starts Windows with a limited set of drivers and services. This can sometimes fix problems that are caused by third-party software or services. To start Windows in Safe Mode, follow these steps:

1. Restart your computer.
2. When you see the Choose an option screen, press F8.
3. On the Advanced Boot Options screen, select Safe Mode with Networking.
4. Press Enter.

Once you are in Safe Mode, try installing the Windows Update again.
7. **Download and install the Windows Update manually.** If you are still having trouble installing the Windows Update, you can download and install it manually from the Microsoft website. To do this, go to the Microsoft website and search for the Windows Update that you need. Once you have found the Windows Update, click on the Download button. Once the Windows Update has been downloaded, run the installer to install it on your computer.

If you have tried all of the above steps and you are still having trouble installing the Windows Update, you can contact Microsoft support for help.
