Windows 7 users should keep AV protection & other security defense systems maximized.  It is probably a better alternative to refresh older machines with new equipment as many WIN7 systems run on older devices & are under-powered for computing needs in 2020.

The Windows 7 upgrade cycle is not as far along as it usually is this far along, Microsoft finance chief Amy Hood said on Monday.Around 23% of Windows desktop machines are still running Windows 7.

Amy Hood, Microsoft’s finance chief, indicated to analysts in January that China’s public health situation and a chip shortage could be factors in the prolonged Windows refresh cycle.  At the time, she issued a quarterly revenue guidance range for the business segment including Windows that was wider than usual to reflect impact from the coronavirus in particular. Then, last week, in the midst of a market selloff, Microsoft said it did not expect to reach that guidance range, sending Microsoft and other stocks lower.

The cycle is not as far along as it usually is at this point in the timeline, Hood said on Monday during a conversation with Morgan Stanley analyst Keith Weiss at Morgan Stanley’s Technology Media and Telecom conference in San Francisco.   Microsoft ended support for Windows 7 in January 2020.
