Check & Speed Up Windows 7 Boot Time
If you want to make Windows 7 faster, you have to know how to measure things, e.g. the Windows 7 boot time. Did you know that Windows 7 provides all the tools to measure the boot time? But there are also useful 3rd-party tools. More after the break.
Average Boot Time for Windows 7
The average boot time for Windows 7 might be 30-50 seconds (to login screen). There is actually no average boot time. Every PC has different system specifications. Drivers, prefetch data, broken devices, etc. can increase the boot time. You should not worry about the boot time to much if it’s less than 50 seconds (to login screen). You can often avoid a reboot by simply logging out of the system.
Boot Time Racer: Compare Boot Times
A decent program to check your boot time is Boot Racer (www.bootracer.com). The program will automatically log your boot time and can store the best results. It’s also important to note that the time to logon and the time to desktop are two different values.
Boot Time to Desktop vs. Boot Time to Login Screen
If you want to speed up the boot time to desktop, you should read this guide: How to speed up Windows 7 boot by disabling startup items. You can greatly improve the boot time to desktop by following it.
In short: The boot time to desktop is often much longer if you have many programs installed that first have to be loaded. It is therefore recommended to get a startup manager for Windows 7.
Check Windows 7 Boot Time Logs (via Windows Tools)
So, basically what we do is to check the Windows 7 event log for the boot time. Yep, that means that Windows does log the boot time anyway and you don’t have to enable it first.
1. Open the Control Panel
2. Click on System and Security
3. At the bottom below Administrative Tools click on View event logs
4. In the left pane uncollapse:
- +Applications and Services Logs (wait for a few seconds!)
- +Diagnostics Performance
5. Double-click on Operational
6. Click on one of the entries with the Event ID: 100
7. Then at the bottom under General you will find a little entry Boot Duration:
8. If you want to find out why the boot time is so slow, click on details.
9. To speed up the boot time you need to find out what is causing the delay. So, check the values carefully and do research on values with a high numbers.
Now identify values with a high value (in ms)
Values that are often very high: BootDriverInitTime and BootPrefecthInitTime. The latter one can be high if Windows 7 stores a lot of prefetch data. We have listed the pros and cons of disabling prefetch to speed up the boot time here. The first one will be high if Windows 7 is loading a lot of drivers. You should remove unwanted drivers and any leftovers (we will be posting a tool to do that shortly).
Simply go through the list of values and try to identify values that are particular high. Remember all of the values are in ms.
The boot time values that you have to check are:
