Microsoft

has announced that it will stop support for Microsoft 365 apps on Windows 10 later this year, effectively aligning the end of support for the operating system on October 14. This move is part of Microsoft’s push to encourage users to upgrade to Windows 11.
“Microsoft 365 Apps will no longer be supported after October 14, 2025, on Windows 10 devices. To use Microsoft 365 Applications on your device, you will need to upgrade to Windows 11,” the company stated in a blog post.
While Office applications will continue to function after October 14, Microsoft warns of potential performance and reliability issues over time.

At CES last week, Microsoft declared 2025 "the year of the Windows 11 PC refresh," emphasizing the importance of upgrading existing Windows 10 PCs over other consumer electronics purchases.
“We believe that one of the most important pieces of technology people will look to refresh in 2025 isn’t the refrigerator, the television or their mobile phone. It will be their Windows 10 PC, and they will move forward with Windows 11,” said Yusuf Mehdi, executive vice president and consumer chief marketing officer at Microsoft.

Microsoft is offering a free upgrade to Windows 11 though it's for a limited time only. However, millions of users are unable to upgrade to Windows 11 due to its stringent hardware requirements, particularly the mandatory TPM 2.0 chip.
To mitigate concerns about the end of Windows 10 support, Microsoft is offering Extended Security Updates for the first time to consumers. Consumers can purchase an extra year of updates for $30, while businesses have the option to purchase up to three years of extended support.

To upgrade your Windows 10 device Via Windows Update, users must first check to see if their devices meet the minimum criteria for upgrading.

Note: If you are using S Mode in Windows 10, switch out of S Mode before upgrading to 11.

Windows 10 is being retired which means there won’t be any security and performance updates, making the machine susceptible to security threats that could lead to monetary damages. Windows will be upgraded to the equivalent versions. For example, Windows Home> edition will upgrade to Windows 11 Home, while Windows 10 Pro will upgrade to Windows 11 Pro accordingly.
