You may have been hearing that Microsoft released a Service Pack update for Windows 7 (called Service Pack 1). To determine if your Windows 7 PC is ready to receive this update, click on “Start”, click on “Run”, then type “wuapp” in the dialog box and click “OK”. This will take you directly to the Windows Update applet in the Control Panel. From there you can view your update history and determine what updates are available (i.e. important updates and optional updates). The Windows 7 Service Pack 1 update will be under the “important updates”. It is from there you can launch the installation of Service Pack 1.
Now, the thing to keep in mind, is that Service Pack updates often can take some time to install; therefore, do not fall for the sense that the install process is hanging. Just be patient and let the install do its’ magic. It is not uncommon for Service Packs to take over 30 minutes to install and the end result often requires a reboot.
You can also download the Service Pack directly from Microsoft from [HERE] ; however, my advice is to go the Windows Update route with this'; especially if it is a home based PC.
Compared to Service Pack updates for previous operating system (such as Windows XP and Vista), the Windows 7 Service Pack 1 update is a piece of cake and is important to install to smooth out any rough edges in the operating system. The good about Windows 7 is that there are very few rough edges.
