SUMMARY

Windows 7 Service Pack 1 (SP1) is now available. Windows 7 SP1 is an update to Windows 7 that contains previously released fixes to specific reliability, performance, and compatibility issues. We recommend that you use Windows Update to install SP1. For more information about how to install SP1 by using Windows Update, see How to install Windows 7 SP1 (http://windows.microsoft.com/installwindows7sp1).

A Windows 7 SP1 Network Installation Package for IT Professionals and Developers is also available at the Microsoft Download Center (http://www.microsoft.com/downloads).

Important If you are updating just one computer, do not download the SP1 Network Installation Package from the Microsoft Download Center. A smaller, more appropriate download is available from Windows Update (http://www.update.microsoft.com/). If Windows Update does not offer you the option to install the service pack, see Microsoft Knowledge Base article 2498452 (http://support.microsoft.com/kb/2498452). If you are encountering a problem when you install the service pack from Windows Update, see Troubleshoot problems installing a service pack for Windows 7 (http://windows.microsoft.com/troubleshootwindows7sp1).

If you decide to install SP1 from the Microsoft Download Center (http://www.microsoft.com/downloads), you can take some steps beforehand to make sure that you have a good experience. This article contains some suggestions.

MORE INFORMATION

Before you install SP1 from the Microsoft Download Center (http://www.microsoft.com/downloads), make sure that you follow these steps.

Step 1: Back up your important files

Back up your files to an external hard disk, DVD or CD, USB flash drive, or network folder. For information about how to back up your files, see Back up your files (http://windows.microsoft.com/en-US/windows7/Back-up-your-files) .

Step 2: Update device drivers

Update device drivers as necessary. You can do this by using Windows Update in Control Panel or by going to the device manufacturer's website.

Important If you are using an Intel integrated graphics device, you should be aware that there are known issues with certain versions of the Intel integrated graphics device driver and with D2D enabled applications, such as certain versions of Windows Live Mail. The versions of the Intel integrated graphics device driver that are known to be problematic are Igdkmd32.sys and Igdkmd64.sys versions 8.15.10.2104 through 8.15.10.2141. For more information about a known issue with these drivers and with Windows Live Mail, see Microsoft Knowledge Base article 2505524 (http://support.microsoft.com/kb/2505524) .

To check whether you are using the Intel integrated graphics device driver Igdkmd32.sys or Igdkmd64.sys versions 8.15.10.2104 through 8.15.10.2141, follow these steps:
  1. Start DirectX Diagnostic Tool. To do this, click Start, type dxdiag in the Search programs and files box, and then press Enter.
  2. Click the Display tab.
  3. Note the driver and driver version.
  4. If you have the Intel integrated graphics driver Igdkmd32.sys or Igdkmd64.sys versions 8.15.10.2104 through 8.15.10.2141, visit the computer manufacturer's website to see whether a newer driver is available, and then download and install that driver.

Step 3: Install Windows Update KB2454826

Install Windows Update KB2454826 from Windows Update (http://www.update.microsoft.com/) if it is not already installed. If you install the service pack from the Microsoft Download Center and do not install Windows Update KB245862, you could encounter a Stop error in Windows in rare cases.

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.

To check whether Windows Update KB2454826 is installed, click Start, type View installed updates in the Search programs and files box, and then press Enter. Notice whether Update for Microsoft Windows (KB2454826) is listed. If the update is not listed, you will have to install it from Windows Update (http://www.update.microsoft.com/) .

Step 4: Check for malware

Check your computer for malware by using antivirus software. Some antivirus software is sold together with annual subscriptions that can be renewed as needed. However, much antivirus software is also available for free. Microsoft offers Microsoft Security Essentials, free antivirus software that you can download from the Microsoft Security Essentials (http://go.microsoft.com/fwlink/?LinkId=168949) website. You can also visit the Microsoft Consumer security software providers (http://go.microsoft.com/fwlink/?LinkId=135654) webpage to find third-party antivirus software.

Important If your computer is infected with malware and you install Windows 7 SP1, you could encounter blue screens or a Windows Update error such as 8007f0f4 or FFFFFFFF. If malware is detected, Windows Update will be unable to install SP1.

More installation notes

  • If you are using a portable computer, make sure that you connect it to an electrical outlet. And, do not unplug or restart the computer during the installation.
  • You will be prompted to restart your computer. Therefore, make sure that you save your work and close all open programs before you begin.
  • Installing the service pack from the Microsoft Download Center will require slightly more hard disk space than installing the service pack from Windows Update. If you have insufficient hard disk space to install the service pack, you will be prompted to free up additional hard disk space.
