Windows Insiders Install Error 0xc1900101
I keep getting error 0xc1900101 when installing Windows Insiders updates. The update causes black screen and pixelation. I’ve tried multiple fixes but nothing works. What should I do?

Is your system booting in secure boot? or legacy, try boot in secure boot efi mode and proceed with update
