I'm assuming you're referring to the section under 'Settings-Update and Security-Troubleshoot'. If so, then there are a lot of sections for Troubleshooting there. Which one/s did you run?
The symptoms were the 1. updates wouldn't finish 2. Windows mail didn't retrieve messages 3. I could access the store but wouldn't download. 4 Office products started with message to repair a file then it would run.
Solution: I ran the troubleshooting and it ran all night. I woke up in the AM and restarted and everything was back to normal. I was like Windows 10 wouldn't allow me to write to files or the SSD.
