With support for Windows 10 set to end middle of October, concerns have been raised about the continued use of this operating system on a global scale.
Data from TeamViewer now underscores these challenges, revealing that over 40% of global endpoints that recently received support via a TeamViewer session still run Windows 10.
The results are based on an analysis of an anonymised sample of 250 million TeamViewer connections initiated between July and September 2025. The sample includes connections from users with both paid and free licenses.
While Singapore leads globally with 59.38% of devices already upgraded to Windows 11, nearly 30% still run Windows 10, leaving many systems exposed once support ends. In a digitally dependent economy advancing under the Smart Nation initiative and amid growing cybersecurity risks in Singapore, even small gaps in system readiness can lead to significant security and operational consequences.
Timely migration to supported systems, such as Windows 11, is essential to maintain business continuity and safeguard against vulnerabilities, performance issues, and costly disruptions.
Jan Bee, Chief Information Security Officer at TeamViewer, says: “In a few days, two in five endpoints will no longer receive patches and updates, leaving them exposed to vulnerabilities.
“Companies and individuals need to upgrade to a newer, supported operating system as soon as possible. Keeping your systems up to date is one of the most effective ways to protect individuals and businesses against cybersecurity threats.”
