Security News > 2022 > January > Microsoft: Windows needs at least 8 hours online to update reliably

The amount of time devices running Windows are powered on and connected to Windows Update is tracked by Microsoft as 'Update Connectivity.

"One of the most impactful things we explored was how much time a device needs to be powered on and connected to Windows Update to be able to successfully install quality and feature updates," said Guyer.

"What we found is that devices that don't meet a certain amount of connected time are very unlikely to successfully update. Specifically, data shows that devices need a minimum of two continuous connected hours, and six total connected hours after an update is released to reliably update."

You can track devices with insufficient Update Connectivity via Microsoft Intune by navigating to Devices > Monitor and selecting either the Feature update failures or the Windows Expedited update failures report.

Insufficient Update Connectivity alerts can also be found via the Summary report in Intune by going to Reports > Windows updates > Reports > Windows Expedited update report.

"If a device has insufficient Update Connectivity, then investigating other update issues is complicated because the low Update Connectivity can create new issues that go away once there's enough connectivity."
