The latest data regarding the market share of operating systems leaves some really surprising data: Windows 7 grows, Linux collapses and Windows XP continues to have an interesting presence. The operating systems market is one of the most difficult to understand and Microsoft is surely still explaining why a large group of users continue to use old operating systems such as Windows XP or Windows 7, even improving their market share during the last month. Windows 7 is an example that the user community is the one that decides when an operating system is dead, and it is not dictated by a company when it stops providing security updates. And it is that although Windows 7 no longer has support for security updates since January of this year, it has improved its market share during the last month to the detriment of Linux that follows a worrying downward trend. If Windows 10 has proven to be a great operating system, although with certain problems in the updates, its growth in the market is not being completely fast and more taking into account that since its premiere on July 29, 2015, it is currently present in 61.26% of teams. The slow growth and acceptance of Windows 10 is due to operating systems like Windows 7 still holding a huge market share, especially in emerging markets. However, Windows 7 is worthy of admiration, given that its share increased from 22.31% in August to 22.71% in September, in a growth similar to that experienced by Windows 10. Data published by NetMarketShare reveal that Windows 7 not only resists dying, but even slightly improves its share in the last 30 days, and in fact they point out that from January to September the system has only lost 2% of its market share. Windows 7 was present in January in 25.56% of computers and is now present in 22.71%. What is worrisome is the fall of Linux that, although it improved ostensibly with the beginning of the pandemic, now as many more companies return to face-to-face work, it is losing importance in favor of Windows 10. However the fall was seen to come, that market share in Linux dropped by 50% last month. Linux is currently present in 1.14% of computers, compared to 2.33% in August. With these 10 simple steps you will be able to configure the security of your Windows 10 account and be the true owner of your personal data and your privacy while using the computer. Separate mention to point out that Windows XP is still there, and in September 2020 it still has a 0.78% market share, and those are thousands and thousands of devices that are still using it.
