Update error code:80070026

I am using Windows Vista Ultimate. I dint noticed that my Windows Update was not running since past 2 months. Also there is no system restore point available on my system. Yesterday when I ran the Window updates, the installation failed with an error message saying something similar to “code 80070026 un known error in Windows update’.

Any idea how this can be fixed ?

As per my experience such problem occurs when your antivirus or the firewall is blocking the installation of Windows Updates.

Usually this use to be the third party Security suites or third party firewall. Hence you just need to disable your antivirus and Firewall while installing the updates. Try out and let me know.

Thanks for the help Hayworth. I tried out doing the same. It is my AVG that I turned off along with the firewall. Now when I try to install Windows Updates, it goes ahead but tell me the version is still “80070026”. As I remember the last I installed was 7.2. is it correct ?
