Launching PowerShell using the Win32 API

I was working on a personal project in C on Windows when I stumbled upon a really strange roadblock: a PowerShell instance would not actually run the script given to it when started via Windows API but it would when launched manually from a cmd.exe.

Eventually the realisation came to me: PowerShell doesn't like the DETACHED_PROCESS option for CreateProcess(). I have no idea what it was doing with it there, but it didn't involve actually working.

I changed it to CREATE_NO_WINDOW and all is fine in the world.

Windows folder extremely slow to load

Due to some weirdness and presumably thumbnail rendering, if a folder is set to "Optimize for Pictures", it takes 10+ times as long as it should to load. This was happening for my Downloads folder. It seems to only apply when it's accessed through "This PC".

Anyway, to fix it, in the properties of the folder in question, under customize, change Optimize this folder for: to General Items and it will work much better.
