So it’s good they’re adding this tool, but sucks that these scenarios are so common a tool like this is needed. However, I’ve seen issues where something gets corrupted, a sfc scannow check is triggered on reboot, and never finds anything. Windows diagnostic troubleshooting is very painful because the OS doesn't give you much information, and what’s there is very obscure. So if this tool is built on that shoddy foundation, I’m not sure it’ll be very successful. There are thousands of guides suggesting an sfcscannow or other disk check and they never work.
