Hello,
What you are experiencing is the effect of how Windows Update is tightly integrated into the servicing model of Windows 11. Even if you pause updates, the operating system still performs component checks and stages update payloads in the background. That is why features like Bluetooth or screensavers stop working properly when updates are pending — the system is essentially in a “partially serviced” state until the update cycle completes. This is not a bug but a consequence of cumulative servicing, where minor monthly updates replace entire component stacks rather than patching them individually.
There is no supported way to change the cadence to fortnightly or monthly while keeping the system stable. The only configurable options are the pause period (up to 35 days) and deferral policies via Group Policy or Intune. For example, in Group Policy under Computer Configuration\Administrative Templates\Windows Components\Windows Update\Windows Update for Business, you can set Select when Preview Builds and Feature Updates are received and Select when Quality Updates are received. Quality updates can be deferred up to 30 days, which effectively gives you a monthly cycle. This is the closest supported method to what you want.
If you disable updates entirely, you will avoid the forced servicing but at the cost of security and compatibility. The better balance is to configure deferrals so updates arrive once per month, and to schedule active hours and restart behavior so they don’t interrupt your workflow. That way you avoid daily checks breaking minor features, but still stay within Microsoft’s supported servicing model.
I hope you've found something useful here. If it helps you get more insight into the issue, it's appreciated to accept the answer. Should you have more questions, feel free to leave a message. Have a nice day!
