and do not work for Windows installed on MacBook Pro
Well yeah, MacBook Pro isn't designed to run Windows. It is designed to run MacOS. The hardware inside it is different from common PCs. And while there are workarounds for that, none are stable enough.
Also, as far as i know, Apple does not officially support Windows on their devices. So, all and any issues one faces, are to be solved by that person. (Or in other words, it's bad idea to run Win on MacBook.)
I meant if they could be found on the hard drive of my laptop if I needed to access it from other laptop.
Thing is, you just can't hook another laptop to your MacBook Pro and bypass all Windows security features to get access to the data it contains. And i'm not allowed to tell if there is any data to be found in the first place.
So it would be great if some one could suggest a way to solve the problem of Windows being stuck on the welcome screen.
Sounds like corrupted Windows. Most likely due to the incompatibility with MacBook Pro hardware. This is the price one pays by using incompatible OS with MacBook Pro.
My advice: format the OS drive and install MacOS back. If you need Windows laptop, buy Intel/AMD laptop, and not Apple product.
Take all of it as life's tax.
