Ey guys, it’s been awhile. And it’s also been awhile since I was bugged with problems with Vista. Your computer may get an error 8000FFF when doing Automatic Updates in Windows Vista. Culprit is most probably the incorrect reporting of the system with 4GB of memory.
To fix this issue, do the following steps:
1. Run cmd [command prompt] as administrator.
2. Type: “reg delete HKLM\Components /v AdvancedInstallersNeedResolving” and then hit Enter.
3. Press “Y” to confirm.
4. Restart your computer and you should be able to run Automatic Updates again.
