He's asking *how it works*, I think. Cheers, Vikram.

Egg-Zactly! I want to know the internals of the Windows Update mechanism, how it works and stuff. Help anyone? :(( :(( Bikash Rai

answers will come if you give people time to, and if - of course - someone knows...

How does Windows Update work? Is downloads a setup file silently in the background and installs it. The Update can also be seen in the add remove programs. How does it do it? Also what happens if the downloading is in progress and the user shuts down the system? Bikash Rai
I believe there's ActiveX involved! A signed ActiveX is installed on your system and then it can do as it pleases.

A signed ActiveX, huh! Any ideas about the installation procedure of the updates and how they show up in the Add-Remove programs list? :confused: Bikash Rai

I can tell you something about the download. That is done via BITS (Background Intelligent Transfer Service) in the background using about 30% of your available network bandwidth. Shutting down your computer while downloading is no problem, BITS resumes the download of the appropriate file the next time you are online again. More information can be found on MSDN.

you did not... it is simply common practice on a web forum (which differs by fact with a chat' forum) that answers may not come instantaneously...

[toxcct][VisualCalc 2.20][VisualCalc 3.0]No, I wasn't looking for any source code, just articles on how MS does it. :) Bikash Rai

Thanks.Read about the BITS implementation and its truly great :), but the sad part, it doesn't work with winME and lower :(. Any free implemention similar to BITS but for WinME and lower? Also, It download MSIs for updates, I think :confused:, but how the heck does it update the OS with MSIs. I want this in my own application but have no clue how to go about doing it. Can you help? :sigh: Bikash Rai

I hope the following helps. If you want help programming it, give me a yell. you can read about msiexec here: About Windows Installer[^] I don't know if this will suit your needs, but it's a place to start: (codeproject) Cool C# File Downloader[^] (C#) File downloading with COM and ASP[^] Sourceforge.net: ImperoUpdater[^] (C#) Sharp AutoUpdater[^] (C#) Also, you can look into implementing something with WinINet: such as with InternetReadFile[^] and InternetSetFilePointer[^] or some of the other Common Functions[^] of
