Windows 10 Insider Preview 17666.1000 - failed install attempt - 0xc1900101

Probably like for most of you, Build 17666 is the first build that failed to install for me since I'm on Win10x64.

Build 17682 now installed successfully but it did not solve all the problems that came with this failed install. I did not do anything special to solve the problem besides giving each new build that came out after 66 a chance.

As it worked now, it seems the problems lies within the build itself (maybe some compatibility problem with our systems).

Maybe you guys have a Dell Studio XPS from 10 years ago like I do? This might be the common link between all of us but just a wild guess. Maybe it's the Radeon 3800 graphic card. Maybe it's the Samsung monitor that I'm using in portrait mode.

Build 66 failed to install and rolled back but still broke two things:

1. My (Dell) ATI Radeon HD 3800 driver stopped working (error 39) and despite all attempts is still not working.
2. My internal USB3 controler (Renesas - was not provided by Dell) seemed to be working but attaching USB3 Disks did not do anything (no lights, no motor turning).

I "solved" 1/ with buying a Geforce GT 1030 (glad that PCI-E ports are backwards compatible - even though it's not going to run full speed which is why I bought this entry level card) and replacing the Radeon. I always liked Geforce more anyway but it's a shame I had to come to that end. I don't know if the card just broke at the same time or what (the default Windows driver was working OK) but I was tired of losing time with this and wanted to upgrade the graphic card for a while anyway.

I solved 2/ by moving the internal controller to a different slot. Not sure why this changed anything but it's working as it's meant to.

Thanks to all for your support and suggestions and I you all now made it successfully to build 17682.

Have fun!

yes- after 2 fails I uninstalled Kaspersky and 17682.1000 installed on the third attempt with no issues and at lightning speed.

Yes it does!
