Slow Solid Edge ST4 Startup Times

With ST4 MP2 and earlier an issue has been discovered that can result in slow Solid Edge startup times.  Specifically the issue revolves around the Most Recently used (MRU) list.

To resolve simply reset the user’s MRU list.  You reset the MRU by deleting the "HKEY_CURRENT_USER -> Software -> Unigraphics Solutions -> Solid Edge -> Version 104 -> MRU" registry key entry.

This issue should be resolved in a future ST4 maintenance pack.


  1. am i suppose to delete them all ?

  2. Delete the entire entry labeled "MRU". Select MRU in the left hand pane, right-click, Delete. MRU will get recreated the next time you launch Solid Edge.
