Windows 10 Update Error C1900101

I have a HP Spectre 13t-3000 and am getting this error code C 1900101 when trying to upgrade to Windows 10.  The download works fine but when it reboots, it asks me to select a keyboard setting and then launches into Windows 8.1.  I have the hard drive encrypted... would that be causing this problem?  Is there a way to fix the install?

I received a C1900101-40017 failure error according to the update log when trying to update from Windows 7 SP 1 to the production version of Windows 10 Home. As far as I have been able to determine Microsoft has no online answer to what this error is or what it means.

I tried the update on an hp G62 Notebook PC, Product number: LD643AV, running Windows 7 Home Premium 64-bit Service Pack 1. It is supposed to be compatible with Windows 10 according to Microsoft specs. So why does it have problems with the upgrade. I think that I will attend next years Microsoft stockholders meeting to see if Mr. Nadella has some answers for why the problems after all the testing. In the meantime, I will be happy that after the failed installation of Windows 10, the software successfully rolled the OS back to Windows 7 and appears to be working okay so far. I sure as heck am not going to update my other hp PCs.

For what it's worth, I had the same problem on my own HP ProBook with an i7 CPU and 16 GB of RAM, running Windows 8.1 Pro 64-bit.

Windows 10 was very insistent in attempting to download and install, even after I had unchecked its box in the available updates listing. I finally had to hide the update to get some peace.

For now, the thing I am least likely to do is to update any of my computers to this version of Windows. Here's the money question: How long will my copy of Windows 8.1 be supported with security updates? I couldn't care less about feature updates.

I thank you for attempting to solve the, problem, but for me it keeps giving that error code, and if this is any use to you, says that it failed during the second boot. Not sure if that helps or not. I'm tempted to try a clean install, but I have no clue if entering in my windows 8.1 pro activation code would work for the windows 10 pro activation. Any help for either the reboot problem or whether a clean install would help?

A clean install of Windows 10 will prompt you for a Windows 10 activation code, which you won't have unless you had successfully upgraded to Windows 10.  It's a chicken-and-egg problem.  I'm in the same boat, with the C1900101 error code.

Yeah. Best types of problems. Though I have found that if you install on a separate partition you can install. Maybe if you transfer the activation file it will work? Not sure if thats even permitted, probably should wait for the microsoft specialist to say whether we can or not. Can't test it at the moment anyways, I'll be away from my PC for about a week. But that might be a quick fix if it is allowed.

Thanks, Ganesh, but I'm afraid the update fails on reboot.

I'm thinking that the best thing for MS to do would be to allow us to generate W10 keys with our present W7/W8 keys and to let us then do our own fresh installs.  The update system is unfortunately unreliable for a number of users.
