  • Type msconfig in the Start menu to open the System Configuration window.
  • On the default General tab, go to the Selective startup section.
  • Deselect Load Startup Items (but make sure the Load System Services option is checked).
  • Switch to the Services Tab, and check Hide All Microsoft Services.
  • Click Disable All, press OK, and restart Windows.
  • Relaunch the Reader and see if the issue still occurs.

6. Troubleshoot plug-ins conflicts
