Windows 10 1803 Update Error 0xc1900101

That's the thing, since Windows 10's inception it has been an up & down affair for me. One Feature Update may install fine (maybe the next) but then it gets out of sync and all hell breaks loose. For example, two of my PCs accepted 1607 then failed miserably w/1709, both required a wipe because the update incapacitated both machines. Then 1803 installed fine on both. Have several other computers that have been all over the map too.

Might have to try your suggestion to prevent my machines from updating but there really shouldn't be the need to do that if MS changed their ways, again never going to happen. And that is exactly why, if I need a Windows PC, we are reverting back to Win7. At least the user has the option to install updates, or not.

From my understanding there are some tweaks / hacks that can be applied if you are running Win 10 Pro that may or may not work to suspend the update process. Not a whole heck of a lot for Windows 10 Home that I have found. A simple dip-switch to turn off would be nice yet do not foresee that ever being an option.

And unless you are prepared to dig into the bowels of the computer to find what may be ailing it (can be very time consuming and hit-n-miss as to whether you'll figure out what it is), your best option IMHO is to attempt a complete refresh (NOTE: back up your data as more than likely ALL will be lost). Can use the Media Creation Tool to fresh install the latest OS too, can be obtained directly from Microsoft. In my experiences (we've had lots on multiple computers) 99% of the time this is what it has come down too. And also in my experience, at some point your computer will no longer have the ability to restore itself to a previous version, nor will a repair work, or system restore, etc. Been there too many times making it hard to believe it'll play-out any different.

Me thinks MS needs to rethink their strategy w/Windows 10 as these updates are very inconsistent as to what the final outcome will be. It's one thing forcing a Cumulative Update but a Feature Update is another - I liken the latter as upgrading your PC to a new OS twice a year which one SHOULD have a choice of whether they want to or not - so achieving success essentially turns into a game of roulette where one Feature Update may install w/o issue but the next not being so forgiving, and round and round we go.

I've personally been giving up and reverting back to Windows 7 as I get to choose if we want updates installed or NOT. Allows for much more stability as one isn't fighting at every turn when an update like on Windows 10 doesn't play nice.

Every month or so my laptop tries to do this update and always fails, no matter how many hours I let it be.  I have to always let it restore to the previous version.  My laptop is an aspire s7 from December 2013.  Yes, it's old(er), but it works fine. How do I get this update to either work for me, or stop the automatic updates?

1. You can stop updates for a while, but it will come back eventually.
2. Looks like you encounter a update fail loop, could be because of older update cache that blocked the new updates from taking over.
3. Either clean all the temporary files, try using CCleaner for this, and then retry the update.

We have no choice but to keep using windows 10 until we have better alternatives. The forced updates and subscription based model sucks, i only have bad wishes for everyone involving in making this in the final product. The karma will get to them.

I would want to resist paying out dollars as well. And that is a valid complaint, no one should have to suffer 3 hours worth of an install process before getting an error message that might have come earlier. There should be a better check up front for issues that might arise.

If you must go to Unix - good luck. Maybe someday pop back in & tell us how it went.
