The title is self explainatory, it's a Windows 8.0 iso with updates up to 2021-03, but it doesn't include just updates, lolno.
Misc things included:
.NET 4.8 (yes, you heard that right, fully working .NET 4.8)
.NET 3.5/3.0/2.0 pre-enabled
Windows Embedded Foundation Packages (in case you want IE11 which is not included)
TLS 1.1 and 1.2 support on IE 10
C++ Runtimes (from 2005 all the way to 2019)
But you might be wondering: Why? Can't you just use 8.1?
1. Why not
2. Some might prefer 8.0 over 8.1
Might update this in a few months.

Hope you enjoy it as much as I did making it.
