Microsoft on Wednesday released for download the beta version of its Windows Live OneCare 2.0, the software maker's all-in-one toolset for PC security and maintenance. The upgrade is expected to improve on the first version, which didn't stack up to rivals in antivirus protection.

The OneCare upgrade offers several new options, such as multi-PC and home network management, and printer-sharing support for local networks.

The upgrade also speeds up PC boot time by removing rarely used applications from the start-up menu, and provides monthly summaries of key activities and recommended actions for PCs on a local network.
Other new features include the ability to centrally configure and monitor backups for PCs covered under the same OneCare subscription, with the data from all the machines going to one location.

The software also can be configured to back up photos and other important data online through Windows Live Folders, which is available at an additional cost.

Finally, the upgrade offers Wi-Fi connection security to protect wireless data transfers. While Microsoft is making a big push into PC security with OneCare, the first version didn't stack up to rivals in antivirus protection, according to at least one independent study.
To beta-test OneCare 2.0 won't cost you a dime, but the full-service version will. Currently, Microsoft charges an annual fee of US$49.95 to install Windows Live OneCare on up to three computers. Prices for version 2.0 have not been released.
