Before you decide you install Windows 7 Service Pack 1, there are a few things you may want to check or ensure. Here is an indicative list.
- Log on to your computer using an administrator account, make sure all other users are logged off the computer, and close all open programs.
- Back up your files to an external location, such as an external hard disk, DVD or CD, USB flash drive, or network folder.
- If you’re using a laptop computer, connect it to an AC electrical outlet and don’t unplug or restart the computer during installation.
- If you have an un-interruptible power supply (UPS) connected to your computer, disconnect the connecting serial cable before installing SP1. The installation automatically attempts to detect devices connected to serial ports, and UPS equipment can cause problems with the detection process. It’s fine to leave your computer connected to a UPS to supply power.
- Install Windows Update KB2454826 from Windows Update if it is not already installed. Windows Update KB2454826 will automatically be installed when you install the service pack by using Windows Update. However, Windows Update KB2454826 is not automatically installed when you install the service pack from the Microsoft Download Center.
- Check your computer for malware by using anti virus software.
- Some anti-virus software might prevent SP1 from installing, or might slow down the installation. You can try temporarily disabling your antivirus software. If you do so, be sure that you’re aware of the risks involved, and be sure to re-enable it after the service pack is installed.
- Make sure you have enough free disk space to install SP1.
- You can use the download the standalone installer to install it or use the Windows Update service, when made available. Windows Update will give you a better installation experience for you.
Your Windows PC will need to reboot after installing Windows 7 SP1, so make sure you save all your work and close your applications before you begin your installation.
