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!

MD5 in 64-Bit OS?

We all familiar with MD5 hashing. But let's see the screenshot below.

MD5 Hashing and File Size

You see, two files with different file sizes are having the same MD5 hash value (8ae6dd9a6d246004da047f704f0cc487). Is it MD5 hash coalition? No, once we use the right tool, md5deep64, we get the right result.

For an explanation of WOW64, see Microsoft documentation on Wow64 and some implementation details.

So, let's make sure you have the right tools for your new 64-bit OS today.
