Hi Ross,
They were not accidental screen shots and even if they were, it would not explain why they were saved in a hidden system file. It has happened 6 times and each time there is a new file named Capture0 stored in a new folder in that path. I regularly take and use screen shots for work so I am very familiar with how to take them and use them so that is why I am 100% certain I did not take and save those files. Something in Windows is taking the screen shot and placing then in the Feedback Hub files and I want to know if those files were sent to Microsoft without my permission.
C:\Users\my username\AppData\Local\Packages\Microsoft.WindowsFeedbackHub_[extended file name with numbers and letters]
