It happened when it ran auto update from windows. After it ran auto update
it could not start anymore. My computer is a Dell and i bought it less
than a
year ago. Yesterday night I could still login once and when i restarted
it, it came back to the same problem
Since you can identify the cause of the issue and since you can login once,
do a System Restore to before you installed the updates. If you can't even
login, you can boot with your Vista DVD and do System Restore from there.
Or you can go to Control Panel>Programs & Features (tick the Show Updates
box) and uninstall whatever updates got installed.
Then go to the Windows Updates applet in Control Panel and change the
setting from Automatic to something like "Download updates but notify me
when they're ready". Then examine the updates before you install them. You
generally don't want to install any driver updates from Windows Update.
To run System Restore, go to the Start Orb and in the Start Search box type
"System Restore" without the quotes. System Restore will appear in the
Programs result. Click on it, allow the UAC prompt, and follow the wizard.
