How to repair Internet Explorer 8 and fixing windows explorer problem

Fix Windows Explorer After Installing Internet Explorer 8.

Important : Enter “regsvr32 actxprxy.dll”

Unfortunately, it seems that installing Internet Explorer 8 (IE8) sometimes has some adverse affects on other applications. Here’s how to fix this.

The problems we’ve experienced following installation of IE8 have been:

• Windows Explorer opens folders in new windows, even if you have “Open each window in the same folder” checked ;.
• “Open in new tab” doesn’t work in IE8;
• Can’t connect to databases using SQL Management Studio Express 2008 (”Unable to cast COM object of type ‘System.__ComObject’ to interface type ‘Microsoft.VisualStudio.OLE.Interop.IServiceProvider’. Exception from HRESULT: 0×80004002 (E_NOINTERFACE)”).

The solution is pretty simple:

1. Go to Start -> All Programs -> Accessories,
2.  right-click “Command Prompt”, 
3. and choose “Run as Administrator”.
4. OK the user access warning dialogs.
5. Enter “regsvr32 actxprxy.dll”.
6. Reboot.

Simples! No more tearing my hair out.
