Are you having an issue when running AutoCAD on Windows 10 whereby if you press the F8 key AutoCAD will freeze for a while. AutoCAD will eventually become responsive again but only after waiting 5-10 minutes.

This issue is caused by the Windows 10 Anniversary update and can affect all versions of AutoCAD and AutoCAD based products.

Unfortunately, this is not a fault with your AutoCAD so we are waiting for Microsoft to fix this update. There is a work around though in AutoCAD whereby you can change a setting which will stop the freezing from happening until this is fixed by Microsoft. The work around to stop this happening is you can set the command “TEMPOVERRIDES” to 0. This will stop AutoCAD from Freezing.

----------------------------------------------------------------------------------------------------------

For AutoCAD 2016, install the AutoCAD 2016.0.10 Update.   

As an alternative, to work around the issue without the updates (and also for AutoCAD 2015/2016), do one or more of the following: 

  • On the command line in AutoCAD, type TEMPOVERRIDES and change the value to 0 (zero).
  • Turn ortho and other functions on and off via the Status Bar.
  • Type in ORTHO at the command line instead of using the function key.
  • Rollback the Anniversary update (Microsoft allows only 10 days to do this).
