But I don't know your PC well enough to see if it's true or not if they apply.
https://support.microsoft.com/en-us/kb/972145 for example doesn't sound too bad to me. And I can see how antivirus+antimalware+firewall apps could block the install.
I also see that some of these presuppose that the machine is in some default Microsoft issue configuration. That is, IE is the default browser, there are no AV systems blocking or protecting the OS.
Wish I had a solid answer for you but I do encounter this. So far, the removal of the AV, setting IE to the default browser often clears it up. Now if there are other factors like a full HDD, well, you can see that I can't guess that.
Some security updates cannot apply to Windows Vista Premium(64-bit retail version, updated to sp2). I tried to download the updates from MS Website and install them manually after the automatic update continually failing to install, but it didn't work either. The error message is "this update is not for your system."
I just didn't understand why these updates are still on the list and my system repeatedly shown/prompted "8 new updates are available if they are not for Vista?"
The 8 security updates are as follows:
I just didn't understand if these updates are not for my system, why the list shown "Security updates for Windows Vista for x64-based Systems."?
The Windows Vista Business, which comes with my HP and Dell computers haven't encounters this problem.
I tried to find a solution from internet but with no result.
Give me a hand, please!
