WIN7 installation update Failure analysis of 8024402F error codes

1, Internet network connection busy, Windows update server update requests too many;

2, the computer runs a program that prevents Windows update service from accessing the Internet. Programs that might do this include firewalls, antispyware software, Web accelerators, Internet Security or antivirus programs, or proxy servers;

3. System service Cryptographic Services or related Windows system files are damaged or missing.

Troubleshooting 8024402f error codes in Win7 installation update

1. Check your Internet network connection, turn off Windows Update, and then restart your computer, try to connect to Windows Update again later, and if you still have a problem, try to avoid the peak hours of the internet and choose a time when the network connection is relatively busy. Try connecting to Windows Update again.

2. Shut down any third-party firewalls, antispyware, Web Accelerator, Internet security, or antivirus programs that have background monitoring before you perform Windows Update, or cancel the proxy server if you use a proxy server.

3, please expand "All Programs"-"Accessories"-"System Tools" in the Start menu, right-click Command prompt, select "Run as Administrator" in the pop-up right-click menu, and then execute at the command prompt: Sfc/scannow, pay attention to the space after SFC.

4, we re-register some system files to register the system file CRYPTDLG. DLL For example, type the following command in the Command line window that you opened in step 3 and press ENTER to perform:

REGSVR32 C:windowssystem32cryptdlg.dll

5, use the same method to register system files in sequence: DSSENH.DLL, GPKCSP. DLL, InitPki. DLL, MSSIP32. DLL, Rsaenh. DLL, Sccbase. DLL, SLBCSP. DLL, Softpub. DLL, WINTRUST. Dll. (Simply REGSVR32 the command to the Cryptdlg in C:windowssystem32cryptdlg.dll.) The DLL part is replaced by the above module files in turn.

6. After you re-register the above system files, reboot the system to allow the system to reload the repaired system service Cryptographic services. Then try connecting to Windows Update again.

This provides a batch file for registering the above file, writes the following code to Notepad, and then saves it as "registered. Bat", noting that the extension is bat, not txt.

REGSVR32/S C:windowssystem32cryptdlg.dll

REGSVR32/S C:windowssystem32dssenh.dll

REGSVR32/S C:windowssystem32gpkcsp.dll

REGSVR32/S C:windowssystem32initpki.dll

REGSVR32/S C:windowssystem32mssip32.dll

REGSVR32/S C:windowssystem32rsaenh.dll

REGSVR32/S C:windowssystem32sccbase.dll

REGSVR32/S C:windowssystem32slbcsp.dll

REGSVR32/S C:windowssystem32softpub.dll

REGSVR32/S C:windowssystem32wintrust.dll

With the above registration system files, the Windows 7 installation update appears 8024402f unknown error should be able to be lifted.
