Hi Obags

Sorry for the inconvenience caused.

Before carrying out this procedure, disconnect from the Internet. That means turning off Wi-Fi and disconnecting from a wired connection. If you don't, Windows 10 will indicate some files are in use and cannot be modified or the command will be non-responsive. Also, you should restart your computer after disconnecting from the Internet. The easiest way to do it is to enable Airplane mode from the Action Center - Windows key + A.

Open Start, type: CMD

Right click CMD

Click Run as administrator

Type each of the following then hit Enter

taskkill /f /fi "SERVICES eq wuauserv" (Do this multiple times)

net stop cryptSvc

net stop bits

net stop msiserver

ren C:\Windows\SoftwareDistribution SoftwareDistribution.old

rmdir C:\Windows\SoftwareDistribution\DataStore

rmdir C:\Windows\SoftwareDistribution\Download

When complete, hit Enter, then restart, then try updating again.

If that does not work..

1. Open Start, type: CMD

Right click CMD

Click Run as administrator

Type each of the following then hit Enter

Run these codes:

Net Stop bits

Net Stop wuauserv

Net Stop appidsvc

Net Stop cryptsvc

Ren %systemroot%\SoftwareDistribution SoftwareDistribution.bak

Ren %systemroot%\system32\catroot2 catroot2.bak

Net Start bits

Net Start wuauserv

Net Start appidsvc

Net Start cryptsvc

After running these commands, check if your issue is fixed.

Hi,

Via https://docs.microsoft.com/en-us/windows/deploy...

0xC1900209 The user has chosen to cancel because the system does not pass the compatibility scan to install the update. Setup.exe will report this error when it can upgrade the machine with user data but cannot migrate installed applications. Incompatible software is blocking the upgrade process. Uninstall the application and try the upgrade again. See Windows 10 Pre-Upgrade Validation using SETUP.EXE for more information.

You can also download the Windows Assessment and Deployment Kit (ADK) for Windows 10 and install Application Compatibility Tools.
