Windows 7 64-Bit to Windows 10 Upgrade Error

New year, new OS install. Windows 10 was lagging badly and took around 20 minutes to boot... sure... it was probably PLEX just trying to checksum 4TB of media, but I was sick of it. So, fresh install of Win7 on that 1TB SSD I installed into my previous Vaio. All went well with Windows 7, apart from crappy installation media... but upgrading to Windows 10 took a lot of effort.

Actually, Windows 7 had enough trouble with its own updates. I think that, nowadays, due to the sheer amount of updates that'll try and download and install (at once) on a fresh Windows 7 installation, it's nearly impossible to have them actually all install and succeed.

Therefore the windows updates process took around 10 reboots, with the progress counter getting to 70% and unwinding with an error... but each time more updates would succeed, so it just seemed that they needed intermittent reboots which aren't automated.

Anyway, once I finally had a Windows 7 desktop with an who-knows-how-successful SP1 install, I did the lovely accessibility Windows 10 update. I am hard of seeing, you see?

I came straight away into this error...

The program can't start because api-ms-win-core-libraryloader-l1-1-1.dll is missing from your computer. Try reinstalling the program to fix this problem. Re-installing what program? I'm running an installer! :)

After a large amount of googling... I stumbled across a one-liner in this post. Someone briefly mentions swapping wimgapi.dll from your c:\windows\system32\ folder into the c:\windows10upgrade folder... it then just worked!

Well.. I hope it will... at least it's installing...
