What can I do if I can't find Win7 SP1 in Windows Update

The official version of Win7 SP1 has been released for a long time, and Win7 SP2 should be able to see the Beta version soon. However, some friends still want to upgrade through Windows Update online. They have encountered a problem: Win7 SP1 cannot be found in Windows automatic update. After all, downloading SP1 package is too large and too slow. The online upgrade method is indeed the most worry-free and reliable. One kind.

What is going on here? Soft media Xiaobian saw an article on Lenovo's technical support website, hoping to help everyone.

Problem Description: When you use Windows Update to check for updates, the option to download Windows 7 Service Pack 1 (SP1) is not available. Reason for the problem: 1. Windows 7 SP1 is installed, or the pre-release version of Windows 7 SP1 is not uninstalled (Windows 7 SP1 RC) 2. The pre-update patch is not installed in place 3. There is a conflict between programs or a missing system file solution:

1. Uninstalling Windows 7 SP1 RC If you have already installed Windows 7 SP1, the Windows 7 SP1 item will not be listed in the list of available updates. This is not considered. If the Windows 7 SP1 update does not display because Windows 7 SP1 RC is installed, you can uninstall it. The safest way is to use “Programs and Features”. In the Start Search box, type: View installed updates and press Enter. Find the "Microsoft Windows Service Pack (KB 976932)", then right-click and select "Uninstall".

You can also use the command prompt to uninstall SP1. In the Start Search box, type: Command Prompt, then right-click and select “Run as administrator”.

(This step requires administrator privileges. If you are prompted for an administrator password or for confirmation, type the password or provide confirmation.)

Type: wusa.exe /uninstall /kb:976932 in the command window. Press the Enter key to execute.

2. Pre-installation patch update KB976902 is a prerequisite for installing a service pack. Check it out and fill it up if you don't have it.

Type in the Start Search box: check for updates and press Enter.

Click “Check for updates from Microsoft Update online”.

Expand “xx important updates available”, find and select the Windows7 updater KB976902, press “OK”Install.

After completing the installation, if you are prompted to restart your computer, please reboot.

Check if Windows 7 SP1 appears in Windows Update? If it still doesn't work, download Windows 7 SP1 directly from the Microsoft Download Center.

3, program conflicts or lack of system files

These situations are more complex and need to be analyzed on a case-by-case basis. Here are just two examples: 1) Application classes: Some programs are equally likely This causes problems, such as when your computer is running SafeCentral version 2.9.0.0 or earlier, you must first update SafeCentral before you can install Windows 7 SP1. 2) Driver classes: Some drivers may also cause this problem. If you use one of the following Intel integrated graphics drivers, Windows Update will not provide you with the update KB2454826 (Windows 7 SP1 will not appear in Windows Update if update KB2454826 is not installed): - Igdkmd32.sys (32 bit ), version 8.15.10.2104 to 8.15.10.2141 - Igdkmd64.sys (64-bit), version 8.15.10.2104 to 8.15.10.2141
