Benchmark Windows boot time
Find out exactly how long your computer takes to show the Desktop and to fully finish starting up.
Measure startup performance instead of guessing how fast your computer feels.
Measure Windows startup time
Startup Timer is a lightweight app that measures exactly how long it takes for Windows to fully boot and which apps make your Windows startup slower. Benchmark your boot time and find out what is holding your computer back.
Freeware. No ads. No nonsense. Latest version: 1.3 (Changelog)
- Supports Windows 11, 10, 8, 7 and Vista
- Setup and portable versions available
Understand what slows down Windows startup
Measure your boot time, identify slow startup apps and compare your results with other computers.
Find the apps that slow startup
See which system processes and installed third party apps make Windows start slower.
Use the results to identify the biggest contributors to startup slowness.
Compare your results
Compare your startup time with results submitted by other Startup Timer users.
The leaderboard shows the fastest Windows 11 and Windows 10 systems, as well as the slowest recorded starts.
Two useful measurements
Reaching the Desktop does not always mean Windows has finished loading.
Startup Timer also measures the time until average CPU usage drops below 5%.
Run without installation
Download the portable version and run the single executable file.
When you are done, delete the file. The setup version is available if you prefer an installed app.
Lightweight and free
Startup Timer is freeware and supports Windows Dark Mode.
No bells and whistles. No nonsense. Sharing your results with the leaderboard is entirely optional.
Start with a clear view of your computer
The main window shows your processor and memory, with the options you need to benchmark Windows startup.
Run a measurement to find out how long Windows takes to start and which apps contribute to the delay.

See where your startup time goes
After your computer restarts, Startup Timer shows how long it took to fully boot and the apps that made startup slower.
The percentage values show how much of the additional startup slowness was caused by each app.
You can choose to submit your results to the public leaderboard. If you do not share your results, no result data is sent anywhere.

Know when Windows has fully started
Startup Timer provides two measurements: how long it takes for Windows to show the Desktop, and how long it takes for the system to fully start.
We define a system as fully started when average CPU usage has dropped below 5%.
