using Windows 10. Now one of the biggest laptop manufacturers has confirmed it’s still seeing huge Win-
dows 10 adoption as well.

There are about 500 million of them capable of running Windows 11 that haven’t been upgraded
This is referring to machines that can run Windows 11 but haven’t yet switched over to Microsoft’s latest op-
erating system. If that wasn’t bad enough there are still millions that can’t upgrade.

There are another 500 million that are four years old that can’t run Windows 11.
Of course, it’s likely that some of these PCs may well be protected by Microsoft’s Extended Security Updates
(ESUs) which offer bug fixes for a yearly fee.
"If you need more time to move to Windows 11, it is recommend you enroll your Windows 10 device in ESU.
You can enroll in ESU any time until the program ends on 13 October, 2026," Microsoft explained.
However, those who haven’t opted in for this service should definitely be on high alert.

"The October 2025 monthly security update will be the last update available," Microsoft warned earlier this
year.
After this date, devices running these versions will no longer receive monthly security and preview updates
containing protections from the latest security threats."
It seems that these warnings may be being ignored and if you are yet to switch them now could be a good
time.
