Beginning in March 2025, Microsoft introduced a feature called Startup Boost for Microsoft 365 applications, designed to accelerate launch times by initiating a background process during system startup. This enhancement allows applications such as Word, Excel, PowerPoint, and Outlook to open more swiftly by ensuring they are effectively “warm started” rather than launched from a cold state.
The underlying mechanism is quite straightforward: under normal circumstances, Microsoft 365 applications do not launch automatically with the system. However, with Startup Boost enabled, a background process is configured to initiate at boot time, effectively mimicking an autostart behavior for the suite. As a result, when a user opens an Office application, the startup experience is significantly faster.
Naturally, the introduction of an autostart process raises concerns about potential impacts on system performance. Microsoft has addressed this by stipulating that the program only activates when the PC has sufficient available resources—specifically, at least 8GB of free memory and no active power-saving mode. Disabling this feature, however, is not entirely intuitive. Users must navigate to in-app settings—such as Word > Options > General > Startup Boost—to toggle it off. While this appears simple, the catch lies in the fact that subsequent Microsoft 365 updates may silently re-enable the feature.
For enterprise environments, Microsoft has included additional controls. IT administrators can use Group Policy to permanently disable the Startup Boost feature, thereby safeguarding system performance. Moreover, Microsoft has adjusted the associated scheduled task to introduce a delay: unless explicitly disabled by an administrator, the Startup Boost process will only activate ten minutes after the PC has finished booting.
According to recent reporting from NEOWIN, Microsoft appears to have modified its default behavior once again. While the feature was initially set to be enabled by default on systems like Windows 11 24H2, it now seems to be disabled by default. Whether this change is the result of a deliberate policy shift or an unintended bug remains unclear, as Microsoft has yet to issue an official statement.
Curious users can manually verify the status of Startup Boost by navigating to the following location:
Type “Task Scheduler” in the Windows 11 search bar, then open Task Scheduler Library > Microsoft > Office. Locate the task named Office Start Up Boost and check its current status. If it is enabled and you wish to disable it, simply right-click on the task and select Disable.
