Why Does Windows Boot Up Time Vary?

Users of Reg Organizer and Autorun Organizer may have noticed that the diagram displays different system boot times, even without any changes made to autostart parameters. There are no changes in the system, but the boot up speed varies. What’s the matter?

The main cause is background processes that take place when you turn on or off the system. Installing of system updates or drivers, background service operations in the system, lags caused by certain applications in the autostart (that happened to execute some planned actions at this particular moment) – all of these can impact boot time. As a result, you see Windows boot up time varying. The more programs that are in the autostart, the higher these fluctuations are.

To estimate boot up time, we recommend using periods. For example, use an average time for the last 3 or 4 reboots.

Some users often wonder why system boot up time increases after autostart optimization. It seems like it should decrease. The reason here is that the system caches autostarted programs in a particular way (the technology is called ReadyBoot) to run them faster. If autostart settings have changed, the system rebuilds this cache, and this takes some additional time. That is why the boot up speed may actually decrease right after you made changes. Also, the background process we discussed above may also contribute.
