What does "User OOBE Create Elevated Object Server" do? in Windows 10 Pro 64 bit

Hi EK. I'm Greg, an installation specialist, 10 year Windows MVP, and Volunteer Guardian Moderator here to help you.

OOBE is the Windows preinstallation environment ("Out of Box Experience"). The error can result from problems during Updates or Version Upgrades, adding new Users or other operations that go sideways. See more about the error here:

Did you make any changes recently?

Can you System Restore to a point before the problem began following this guide: http://home.bt.com/tech-gadgets/computing/how-t...

You can System Restore from Repair Mode if it will not work in Windows, following one of these paths: https://www.tenforums.com/tutorials/2294-advanc...

If you had a recent Version Upgrade you can roll it back in Recovery Settings.

If you added a new User you can remove it in Settings > Accounts > Family & Other People. Restart PC and add it back.

Go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done: http://answers.microsoft.com/en-us/windows/wiki...

Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files, and also Step 16 to test a new Local Admin account. Then continue with the other steps to go over your install most thoroughly.

If nothing else helps you can run a Repair Install by installing the Media Creation Tool and choosing from it to Upgrade Now. This reinstalls Windows in about an hour while saving your files, apps and most settings, solves many problems while also bringing it up to the latest version 1903 which you need anyway and by the most stable method. http://windows.microsoft.com/en-us/windows-10/m....

But remember that in Windows 10 everything depends upon the quality of the install, and Factory or Upgrade installs are inferior installs which most enthusiasts won't even run because they'd expect endless issues. Consider now or later doing the Clean Install in this link which compiles the best possible install that will stay that way as long as you stick with the tools and methods given: http://answers.microsoft.com/en-us/windows/wiki...

There is also an automated Fresh Start that reinstalls WIndows while shedding corrupting factory bloatware, saves your files, but doesn't clear the drive to get it cleanest: https://www.howtogeek.com/265054/how-to-easily-...

I hope this helps. Feel free to ask back any questions and let us know how it goes. If you'll wait to rate whether my post helped you, I will keep working with you until it's resolved.
