Windows Hotfix Downloader is a portable tool which aims to give you more control of your Windows updates.
At its simplest, you might just use the program to download the list of updates for any or all of its supported products: Windows 7, Windows 8.1, Office 2010/ Office 2010 SP2, Office 2013/ Office 2013 SP2 (both 32 and 64-bit editions are covered).
You're able to browse the list and view the Microsoft support pages for any particular update with a click or two. Any or all of the updates may then be downloaded and installed on your current PC, or saved for use on another system (handy for computers which don't have a permanent internet connection).
The program can also integrate updates, language packs, service packs, drivers and more into your Windows and Office setup discs, so any installation will be just as you'd like, no further manual updates required.
There are bonus tools to help you create bootable UEFI flash drives for installing Windows 7/ 8/ 8.1, create a bootable Office ISO image, even back up your drivers (slightly off-topic, but still useful).
You get some thoughtful settings, too. The program can prevent your PC from sleeping while Windows Hotfix Downloader is running, for example. You're able to set the priority of the update process. And there's an option to limit the program's bandwidth use, so limiting its impact on the rest of your system.
