This may occur if a malicious user is able to successfully log into an account where the UPLEVEL service has been configured and is running. If this happens, the user may be able to gain elevated privileges on the system. Microsoft is aware of this issue and has released a patch for Windows 7/Server 2008 R2 and Windows 8/Server 2012. Uplevel is disabled by default on newer operating systems, and you should verify that it is enabled on your system. To do this, open the Windows Control Panel, click Administrative Tools, and then click Services. Look for the User Profile Service link. If it is not enabled, then you need to do so. After enabling the service, you need to make sure that it is running on a high priority. The next step is to verify that Uplevel is running on your system. To do this, open a command prompt as an administrator and run the following command: sc query uprofile If you see Microsoft Windows is not currently configured to start the User Profile Service, then you need to follow the steps above to enable the service. After doing that, you need to make sure that it is running on a high priority, and then you need to restart your computer for the changes to take effect.
