If you purchased a retail copy of Windows 7, chances are your installation disc didn’t come with SP1 included. That means if you want to reinstall Windows 7 at a later date you’ll have to reinstall from the disc, then download all of those updates again, a time-consuming and frustrating process.
here’s another problem too: should you ever want to perform a repair installation of Windows 7 by choosing the “Upgrade” version, typically to fix a major system problem, then you’ll have to uninstall SP1 first from your computer before doing so – more time wasted and hair lost.
The answer lies in getting hold of a copy of the Windows 7 installation disc with the Service Pack 1 updates already included. You can do this manually using a tool called RT Seven Lite, but yet again it’s time-consuming, fiddly and – you guessed it – potentially frustrating.
Alternatively, you can download a legitimate image of the Windows 7 disc with the SP1 files already included. All you have to do is download the ISO file here, then burn it to disc by double-clicking the file and popping in a blank DVD when prompted. Once done, boot from the disc to verify it works and label the disc accordingly. You’ll need the product key that came with your computer to activate Windows 7 after reinstalling from scratch.
Note that this won’t work if you have a version of Windows that came preinstalled with your computer. Also make sure you download the correct version of Windows 7 for your needs – to find out which edition (Home Premium, Professional or Ultimate) and type (32-bit or 64-bit) you need, click Start, right-click Computer and select Properties.
This downloadable file is for Windows 7 Ultimate SP1 64-bit users.
The recommended (and easiest) way to get SP1 is to turn on automatic updating in Windows Update in Control Panel and wait for Windows 7 to notify you that SP1 is ready to install. It takes about 30 minutes to install, and you’ll need to restart your computer about halfway through the installation.
To check if Windows 7 SP1 is already installed on your PC, select the Start button, right-click Computer, and then select Properties.
If Service Pack 1 is listed under Windows edition, SP1 is already installed on your PC.
Before you begin
Check if your PC is 32-bit or 64-bit
You’ll need to know if your PC is running a 32-bit (x86) or 64-bit (x64) version of Windows 7. Select the Start button, right-click Computer, and then select Properties. The version of Windows 7 is displayed next to System type.
