Hi Stefan,
Thanks for your message. You are however in the German Community and may speak German as otherwise the bandwidth of people being able to support you might be limited. If you prefer English Support just change your thread to the English community by changing the language.
However I will try to assist you on this one right now. Are you running your Surface Go on Windows S mode?
Both files are system files and shouldn't be touched. Is everything working on your device and what actions were you taking when these entries appeared?
With this information in place we hopefully will be able to help you.
Looking forward to hearing from you.
Best regards,
Andrea
