Are you getting this http://runonce.msn.com/runonce2.aspx? Looking for Run Once / runonce Fix answers in IE7? You’re just in luck. I have compiled a couple of good workarounds that can clear that annoying issue out on your Internet Explorer 7

GPEDIT.MSC Workaround:

  2. Click Start\Run and type gpedit.msc, then press OK
  3. Under Local Computer Policy; select Administrative Templates\Windows Components\Internet Explorer
  4. Select prevent performance of First Run Customized Settings
  5. Enable this setting, and then select Option 1 to go to your default home page, or Option 2 to get the default Internet Explorer welcome page.

REGEDIT Workaround:

  4. In the right-hand pane, right-click on RunOnceHasShown and change the value to 1
  5. Close Regedit and restart Internet Explorer 7

Adding a .reg file Workaround

Open Notepad.
Copy and paste the following into Notepad:

Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main]
“RunOnceHasShown”=dword:00000001
“RunOnceComplete”=dword:00000001

Save the text file as IE7_RunOnceComplete.reg.
Double-click the newly created file.

The file will be merged to the registry. A confirmation box will appear, click OK.
Restart the computer for the change to take affect.

TRUSTED SITE Workaround:

  1. Click Tools > Internet Options
  2. Click on the Security tab
  3. Click on Trusted Sites and then the Sites button
  4. Add the following site to the trusted zone: *.msn.com
  5. Click Add and then uncheck the Require server verification (https:) for all sites in this zone and click close
  6. Click OK

For Windows XP users who upgraded to IE7, I’m sorry if any of theses didn’t work for you but you can always go back to IE6 (which is much stable) by simply uninstalling IE7 in add/remove programs under control panel. I’m pretty sure runonce will not show up again.

But if I were you, I’ll shift to Firefox and quit using IE. Just a suggestion. ;-D
