Why won't service pack 1 install properly and how do I fix it?
The underlying problem is that the Windows Update self-update mechanism is not working.
However, this error does not occur if you are using a WSUS server, but the client still won't self-update.
It is therefore possible that error 0x80190194 is not directly related to the problem.
Microsoft Support advised me that the problem is being worked on and that a KB article will be released in due course. In either case, once Service Pack 1 is installed, Windows Update will offer some additional updates and then Service Pack 2. Note: Microsoft provides free phone support for problems installing service packs.
If you install Windows Vista RTM and run Windows Update, many updates are offered and will successfully install.
Once all other updates are installed, Windows Vista service pack 1 is offered.
When you attempt to install Windows Vista service pack 1, the service pack installation wizard appears, presenting the license agreement and so on.
However, shortly after the installation starts the wizard disappears.
Windows Update says that the update was installed successfully.
However, service pack 1 is not in fact installed, and will be detected as needed again on the next update check. On checking the Windows Update log () the client version is 6.0.6000or 6.0.6001
There is a message saying "Skipping Self Update check based on the /SKIP directive in wuident".
There may also be an error 0x80190194 appearing, associated with the URL
