Windows users who do not power on their computers regularly are facing significant delays and multiple reboot cycles due to the way Microsoft handles cumulative updates.
Recent testing on a Lenovo Yoga Slim 7x, which had been inactive for six months, revealed a three-hour wait time involving four separate rounds of reboots to reach the current Windows 11 build.
This issue stems from the architecture of Microsoft's update delivery system, which relies on a chain of prerequisite patches.
The cumulative update hurdle
"Windows updates are cumulative but not infinitely so," Chongwei Chen, President and CEO of DataNumen, told The Register.
Chen explained that Microsoft periodically releases 'baseline' rollups. This means a PC that has been offline for months cannot jump directly to the latest patch.
Instead, the system must first install intermediate updates to reach a specific state. Each of these intermediate steps may modify system files that require a reboot to replace while Windows is not running.
This process creates a bottleneck for hardware used only for specific, short-term tasks. For example, dedicated video conferencing laptops used in professional or communal settings often face aggressive update alerts immediately upon being powered on.
Users often lack the time to sit through lengthy download and installation cycles, especially when hardware is pulled from storage minutes before a scheduled meeting. While Microsoft has moved toward more background updates, the requirement for specific system states remains a barrier for intermittent users.
