How to Fix non-reponsive and/or Slow Tab Issues in Internet Explorer 8

A friend of mine has been having issues for sometime when opening new tabs in Internet Explorer 8 in Windows Vista. Some would open fine and load the sites. Others would hang or timeout. Once one tab had failed, the rest would too until IE8 was closed and reopened. After numerous registry edits and disabling of plug-ins and ActiveX controls we finally found a solution.

On occasions when installing IE8, "actxprxy.dll" fails to register and can cause slow or non-responsive tabs. Actxprxy.dll is a module that contains functions used for Marshaling of ActiveX COM interfaces in IE.

To fix this all you need to do is register the DLL File.
  • Start by loading an administrative command prompt.
  • Do this by right clicking the command prompt shortcut and clicking "Run As Administrator."
  • At the command prompt make sure you are at c:\windows\system32, type "regsvr32 actxprxy.dll" (without quotes) and press Enter.
  • The DLL should register with the system and you should get the following confirmation.
  • There is a possibility that you will need to follow the same procedure for "shdocvw.dll" aswell.
  • When this is done reboot your computer and test Internet Explorer 8. Try opening several tabs and websites at once. The problem should now be resolved.
Many thanks to for providing information.
