Startup Timer review
A free Windows utility for measuring startup delays and locating slow processes.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Startup Timer is a free Windows desktop utility for people who want to measure and diagnose slow boot performance. It records how long Windows takes to reach the desktop and how long the system takes to complete startup. The utility then identifies system processes and third-party applications associated with slower startup, giving users a clearer view of where boot delays occur. It is designed for Windows 10 and 11 and suits anyone investigating startup bottlenecks rather than looking for a broad PC maintenance suite.
Its main strength is the depth of its startup timing focus. Startup Timer separates the time needed to reach the Windows desktop from the time needed for Windows to fully start, so users can compare two stages of the boot process. Results can also be compared with other users through a leaderboard, adding a reference point for startup performance. Windows Dark Mode support is included, and the software is available either as a portable executable or a standard setup download. The portable option can suit users who want to run the utility without a conventional installation.
Startup Timer is a diagnostic tool, not a repair or optimization package. It identifies processes and applications that slow startup, but it does not provide corrective startup optimization features or general PC-maintenance tools. That makes it a focused choice for measuring and investigating boot delays, especially when portability and a free price matter. Users seeking a tool to manage broader system maintenance or apply startup changes should choose a product with those capabilities instead.
