I PURCHASED A WINDOWS LIVE ONECARE BOXED PRODUCT OR TOKEN (PRODUCT KEY) FROM A RETAILER A WHILE AGO, BUT HAVE NOT INSTALLED IT YET. CAN I STILL USE ONECARE?
Windows Live OneCare will no longer be available for sale after October 15, 2009. This page is intended to provide guidance and answer questions for customers as we complete this process. If you have purchased a Windows Live OneCare fully packaged product in a retail store or have purchased a Windows Live OneCare activation token (product key) but have not installed it on or before October 15, 2009, you will not be able to use Windows Live OneCare. In this case, you may be eligible for a refund.
