Can you try Shift + F10 at the login screen to access a command prompt?
If so, try it from there.
Otherwise, try it one more time and see if it shows up in the lower left corner of the login screen without rebooting
To logout (if you can access the Run command with Win + R) type "shutdown /l" (without the quotes)
Regardless, try it one more time - if it still fails, then you have to presume a problem with the OS.
It's possible that this could be due to an infection.
You may want to try some bootable diagnostics (to include malware scans).
Here's a link to the one's that I use: http://www.carrona.org/initdiag.html
Then try this stuff (in this order):
- System Restore to a point before this started happening.
- DISM/SFC repair (may not work from the command prompt in Startup Repair - but it's worth a shot)
Then please run the following DISM commands to see if there's any problems with the system (from an elevated (Run as administrator) Command Prompt). Press Enter after each one:
Dism /Online /Cleanup-Image /ScanHealth
Dism /Online /Cleanup-Image /CheckHealth
Dism /Online /Cleanup-Image /RestoreHealth
FYI - I have repaired systems using the last command even though problems weren't found with the first 2 - so I suggest running them all.

You can also run sfc.exe /scannow from an elevated (Run as administrator) Command Prompt to check for further corruption.
- RESET using the "Keep My Files" option
- Repair install of the OS (Thanks to FreeBooter!):
"How To Perform a Repair Installation For Windows 8, 8.1 and 10"
- RESET using the "Remove Everything" option (W8 calls this a RESET; W7 and earlier doesn't have this function)
- Wipe and reinstall from the Recovery Partition or from Recovery Media - to include deleting all partitions.
