Windows Live OneCare Troubleshooting

Reader Question:
“Hi Wally, I am having problems with Windows Live OneCare and wondering how to fix it?” - Adam J., USA

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win 10, 8, 7, Vista, XP and 2000 – Microsoft Gold Certified).
Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.

Overview of Windows Live OneCare

Windows Live OneCare is a security suite offered by Microsoft that works with Windows XP and Windows Vista operating systems. Windows Live OneCare included a personal firewall, PC tuning, backup service, and anti-virus program. Windows Live OneCare was released in 2006.

The security suite portion of Live OneCare was not free and users needed to purchase the service on an annual subscription basis. Although Windows Live OneCare is no longer available for purchase, those with an existing subscription will continue to be able to use the service.

Windows Live OneCare performs several tasks on a regular basis. Defragmentation and disk cleanup is done on a monthly basis. The service also ensures all virus definitions are updated regularly and Windows updates are installed as soon as they become available.

Users can schedule regular backups of their important files. Backups can be done over the network to another compute or to external media like flash drives or DVDs.

In 2009, Microsoft Security Essentials replaced Windows Live OneCare.

What Problems are Associated with Windows Live OneCare?

Some users have reported that Windows Live OneCare will begin producing an error message when the computer is started stating, “Windows Live OneCare cannot continue. The Windows Live OneCare is not working or has been stopped.” Often restarting the computer will resolve the issue.

Sometimes this message is displayed the first time a computer is started after installing an update to Windows Live OneCare. In those instances, the computer may need to be restarted several times before the service begins working again.

On rare occasions, Windows Live OneCare needs to be uninstalled and reinstalled. If Windows Live OneCare is uninstalled and reinstalled, it sometimes has difficulty validating its registration. The most common reason for this is if the program is uninstalled using the “Add or Remove Programs” interface.

Windows Live OneCare has a special uninstall tool that can be downloaded from the Microsoft web site. Uninstalling the program again using the special uninstall tool will allow Windows Live OneCare to validate correctly the next time it is installed. Sometimes the user will need to contact Microsoft Live OneCare support in order to have the validation completed successfully.

Is Your PC Healthy?

I always recommend to my readers to regularly use a trusted registry cleaner and optimizer such as WinThruster or CCleaner. Many problems that you encounter can be attributed to a corrupt and bloated registry.

Happy Computing!
