Old news but did anyone know that a researcher had found another privacy issue in Windows as the OS had been discovered to be striping and storing text from email, contact and document files in a file called WaitList.dat seemingly irrespective of if the original text has been deleted?
(C:\Users%User%\AppData\Local\Microsoft\InputPersonalization\TextHarvester\WaitList.dat)
This seems to be a part of the touchscreen handwriting recognition features and has only been found to happen if the feature is enabled.
