It is because windows boot manager is set for 30 sec as default time and you can edit it by editing boot manager file, it is possible by using 'system configuration utility' window. But here shown method only works for windows boot manager if you have Linux OS install alongside windows than it use another method.

Open 'run' dialogue and type 'msconfig'

click on 'boot' tab

Here edit the 'Timeout' field, as default value is 30. You can decrease and increase it according to your need
