In windows 10, when you try to open Device Manager or Services console (services.msc) or Disk Management (diskmgmt.msc), you may get this error from Microsoft Management Console (MMC): Not enough storage is available to complete the operation’. Even though your hard drive and C drive has lot of free space, this error won’t give any clue of what’s wrong.

You can try the following to see you can access the those Windows services again.
1. Open Disk Cleanup and delete temporary files, clean the files manually in folders by running temp and %temp% commands in Run dialog.
2. Disable all Windows startup items by visiting Startup tab in Task Manager to see it solves the issue.
3. Open System configuration tool by running msconfig in Run dialog, and see if loading windows 10 with diagnostic startup or selective startup helps.
4. Hold Alt and double click on ‘This PC’ to bring up System page, click Advanced Settings, and under Performance, choose ‘Adjust for best performance’, click ‘OK’..
5. In the Performance Options, click Advanced and increase Page file size to see it helps.
6. Try to restore your computer to a recent restore point.
If nothing mentioned above helps, you need to reinstall Windows (by keeping files and apps) without doing Reset, here is how that can be done.
Though this is easy to suggest, but we’ve tried all possible ways to fix the error, but reinstalling Windows has done the trick for us.
