The article does note that 0patch, a third-party security platform from the Slovenia-based digital security lab ACROS Security, "will support Windows 7 with at least two additional years of critical security updates." (The cost: around $25 per year. Microsoft won't release updates for it anymore, even though there is still demand for that. Windows 7, which receives the last ESU patches on Tuesday as well, looks to be in a similar situation on first glance. Browsers and other programs will stop getting updates, and some websites will refuse to work as new technologies are no longer supported by the browsers. Windows 8.1 users may continue using it, but the system's security issues will no longer be fixed by Microsoft or anyone else. Once the last patch has been released, it is game over for the operating system. In statistics, the mean squared error ( MSE) 1 or mean squared deviation ( MSD) of an estimator (of a procedure for estimating an unobserved quantity) measures the average of the squares of the errors that is, the average squared difference between the estimated values and the actual value. Windows 8.1 does not get the same Extended Security Updates treatment that Windows 7 received for the past three years. "Windows 8.1 receives one more batch of security patches on the coming Tuesday," reports Ghacks, "before Microsoft lays the operating system to rest."
