I'm currently on windows 7 and whenever I run Windows 10 upgrade assistant it gets to 99 then tells me I'm missing api-ms-win-core-libraryloader-l1-1-1.dll. I've tried running it on a clean boot, I've ran system cleanups to repair any corrupt files, I tried removing my antivirus, and still it won't work.

Does anyone have any other methods to fix so I can upgrade? any help appreciated!

    You don't have to download it. It is already present in C:\Windows\System32 folder. Just copy it and paste it in the C:\Windowsupdate folder.

    I had shoulder length hair BEFORE I started this process.....now bald!  It's a real pity that Microsoft couldn't be more proactive with these common problems!
