We need to re-install windows xp for many reasons. After installing xp, again we need to update windows (hotfixes). So, downloading these hotfixes is very boring, time consuming and one kind of bandwidth loss. So, to solve this problem, you should download all the windows update files. But doing this one by one, it is not possible, you know!
Windows updates Downloader does it very nicely for it. Once downloaded from it, you need a list for the update files. It can be found here. The list is for windows xp professional sp2. If you use another version of xp, download it from that website. After downloading the list, install it. Open the windows updates downloader, select as you need and Download. Enjoy….
