Failure to install Windows 10 April Update(version 1803)

I am unable to install The Windows 10 Feature update to OS version 1803(from version 1709) on my PC.

It is giving 0xc1900101 error. I have all the latest drivers on my PC. The current OS build of my PC is 16299.371.

After each failure, the update gets downloaded again and it has failed 5 times.

I would be grateful if someone could please help.

Brilliant!

This worked for me as well.

After huge grief trying to get 1803 into my machine last year, I have been hiding from Microsoft behind 'Metered connection'  When I finally finally let them in this month, they sent the May 1019 update and surprise, surprise,  I was back in the old install-failure loop.  However using the exe on the above link worked.  (It did take an age though).

The "Microsoft" solutions of the problem for those they tried already nearly everything are uneffective...

Here is a link, that really helped me after 1 year and three months:

It is an older article so changes that I made:

  1. installable media for 1903

  2. ... the same ...

  3. ... the same ....

  4. ... the same ...

  5. It refused to upgrade directly o the 1903 version from my old 1709 version on the C drive, so:

    - I upgrade it at first step to 1809 -fortunately I had a saved ISO version :-)

    - in the second step the UpGrade from 1809 to 1903 was already successive

Good luck!

If anyone needs older ISO images of W10, I have these ones saved: 1803,1809,1903. Unfortunately you are unable to get them directly from Microsoft, only the latest version.  :-(
