I had a problem with "UserNotPresentSession.etl". It was overloading my SSD (100% activity, ~50MB/s writing) for example when I was playing GTA V. I didn't find any information how to disable it, but I found this reddit post: https://www.reddit.com/r/techsupport/comments/524d4s/disk_usage_raising_to_100/d7h7xwt/ where somebody described the same problem.
I found a solution for this problem, by setting "UserNotPresentSession.etl" to Read-only.
- Go to: "C:\Windows\System32\SleepStudy".
- Click the right mouse button on file: "UserNotPresentSession.etl" and then "Properties" from the list.
- Check "Read-only" checkbox and save changes.
- IMPORTANT: Restart your computer.
After that the disk is not longer abused. I experienced this problem on Windows 10 builds 14393 and 15063.
I hope this post will help people with the same issue.
