What part of GDPR does it infringe?
The P part. It's taking screenshots of your screen every few seconds. When enabled, yes, but it makes you wonder why Microsoft is making it so you can only disable it, but not uninstall it. If you wanted to be sure it was disabled, you'd uninstall it... but you can't. I'm sure Microsoft would never enable it by default after an update.
I meant what article(s)/paragraph(s) of GDPR. GDPR is a specific law, not a general principle. You can read it here: https://eur-lex.europa.eu/eli/reg/2016/679/oj#d1e1374-1-1
