Windows Update Error 80240030

When you get the Windows Update error code 80240030, then you are most likely having issue with:

• Can't update your windows. Windows Update fails.
• Can't access your proxy setting in MSIE. IE crashes once you click the "LAN setting".
• IE can't access Internet (thru proxy).

I'm having all these issues since I upgrade to IE9. And here I find the solution to fix/repair  the 80240030 error for me:

1. Open command prompt (with Administrator mode).
2. Type "netsh winhttp reset proxy"
3. Type "net stop wuauserv"
4. Type "net start wuauserv"

It does works in Windows 7 (32-bit & 64-bit) too. Enjoy!
