I have get impression that about 4-6 years old computers act better with Insider Previews than new computers?
Hi Pauli,
My machines are a mixture of old and new and they behaved the same in this case with error 0x800f081f .
I wonder if removing the System>Storage>Temporary files "Windows Update Cleanup" ,besides removing the Uninstall capability for some updates, could also be the cause of the error when they reuse the same kb# (kb5000842) for both .899 and .906 ?
I don't remember if I did a cleanup after installing .899, but it is quite possible given that it takes several GB.
I assume you did not remove "Windows Update Cleanup" and that could explain the difference ?
Edit:
I think I just proved my theory, leaving the "Windows Update Cleanup" alone allowed W.U. to update from .899 to .906 without the error 0x800f081f.
Looks like that is the bug, it should not need that folder to update to the next version of kb5000842.
When they release the fix I still have a backup of the failing one to verify that it works.
