I've just upgraded a computer from the previous Win10 to Win10 AE.
I have a compiled AutoIt script which I use to read in text files from a folder and write them out again after modifications. This has worked for years.
The files were partially corrupted today. I repeated it to check.

Moving the files and script to another computer (earlier Win10), it ran fine.

I doubt there would have been a change to how Windows reads and writes to the file system??
I'll ask in the AutoIt forum, as they may have an idea of what's happening.
