I had tried to install the latest version of Windows 10 (at this time 1909, the September 2019 version), but it had failed with a blue screen. I kind of ignored it, because I thought they will probably fix it or maybe it's because my laptop is new and so on. But recently I got this warning in Settings Windows Update: "You’re currently running a version of Windows that’s nearing the end of service. We recommend you update to the most recent version of Windows 10 to get the latest features and security improvements".
So I tried to install it again. Same thing: a blue screen with a creepy smiley telling me it has failed to boot, with a stop code of "MEMORY MANAGEMENT" at FIRST_BOOT when BOOTing. Well, no shit, Sherlock! I tried to install it using the Media Creation Tool (which I recommend when you have Windows Update issues because you can download the update and save it into an ISO, so you can try it again and again without redownloading everything) and I got a more specific error: "0xC1900101 - 0x30017". What does it mean? No one knows, but it led me down a rabbit hole of people having a lot of different issues.
This post will not discuss every single problem out there, you can search for yourself, I only wrote this because in some obscure corner of a forum I saw one person saying he solved by uninstalling Diskcryptor, a software that I had also installed, but never used. Once I uninstalled it, the update went without a hitch.
- if you have Diskcryptor, uninstall it. You can re-install it later.
- download the Media Creation Tool for your service pack
- tell it to download in an ISO file
- mount the ISO and install from there
- check what error you get
- Google for it until you find someone having had the same specific problem
