Your screenshot indicates your version (1709) of Windows 10 is 9 years out of date, all normal methods to upgrade your Windows 10 version to 22H2 will fail because your current version is too old to update.

The only working method to upgrade your system would be to backup all your files, then create a bootable Windows 10 USB on an empty 8GB USB flash drive, then boot your PC from that to clean install Windows 10 22H2.

Click this link: https://www.microsoft.com/software-download/windows10

to download the Media Creation Tool (Click on Download Tool Now), with that you can create a bootable USB flash drive (min 8GB) using that tool.

Then, Boot your PC from the Installation Media you just created to begin installing Windows 10

During the installation process skip the steps which ask for a product key and select the option 'I am Reinstalling Windows 10 on this PC'.

Yes, that is correct, you can do that, you can insert the SSD and clean install Windows on the SSD using a bootable Windows USB.

0xC1900101 usually indicates a driver-related upgrade failure. Since Windows Update and Update Assistant already failed, use this order of troubleshooting:

Free enough disk space Windows needs at least 16 GB free for 32-bit or 20 GB for 64-bit during upgrade.
Disconnect nonessential hardware Unplug USB drives, external disks, docks, printers, scanners, and other peripherals not needed for basic use.
Update Windows and drivers Run Windows Update again and install all available updates, including hardware and third-party driver updates.
Check Device Manager for driver problems
- Open Device Manager
- Look for devices with a yellow exclamation mark
- Right-click the device and choose Update Driver Software or Uninstall
Remove third-party antivirus/security software Non-Microsoft antivirus can block upgrades. Make sure installation media and product keys are available before uninstalling. Windows Defender can protect the device temporarily.
Run a clean boot A clean boot helps prevent background apps and services from interfering with setup.
Repair disk errors Open Command Prompt as administrator and run:
```
   chkdsk /f C:
```
Restart when prompted. This checks and repairs drive errors.
Repair the Windows image Open Command Prompt as administrator and run:
```
   DISM.exe /Online /Cleanup-image /Restorehealth
```
Run the Windows Update troubleshooter again Go to: Start > Settings > Update & Security > Troubleshoot > Additional troubleshooters > Windows Update > Run the troubleshooter Then restart the PC and check for updates again.
If Windows Update still fails, use an ISO-based in-place upgrade A Microsoft Q&A accepted answer for this error recommends doing a clean boot first, then starting setup from a Windows ISO. Another accepted answer recommends using the ISO when the feature update is not offered or repeatedly fails.

Also note: Windows 10 support ended on October 14, 2025. Moving to Windows 11 is recommended if the device supports it.
