Windows Live One Care is a utility designed by Microsoft to scan your computer for several different issues. Live One care scans your computer for unnecessary temporary files, invalid registry entries, open ports, malware, and even checks your hard drive to see if defragmentation is necessary.
The service is free for ninety days after which time there is a required yearly fee of $49.95 to maintain a subscription. Microsoft has deployed this utility to help users maintain security and functionality of their computers.
If you decide to acquire use of this utility they do require you uninstall any third party virus or firewall applications. If you have already purchased one of these types of applications this can be problematic as you will lose the use of the paid subscription to the third party service.
Overall this utility seemed to work well. Unfortunately there does not seem to be any detailed information as to what the scan has found. When trying to review the registry entries that were flagged as errors I could not locate any detailed information on the entries and what they may relate to.
Microsoft seems to counter this by stating if you have any undesirable effects to use system restore which will reverse any registry changes. This seems to be counter productive.
