![]() Fast startup begins with the shutdown process and includes writing data to disk similar to the hibernate process. Starting with Windows 8.x, the default shutdown and restart scenario has been updated and named fast startup. Understand that hybrid drives are beneficial to on/off performance and consider using the new Hybrid Drive Hinting feature. On average, the hiberfile read/write times represent 50% of the boot to Start screen time.Ī faster HDD/SSD can mitigate the effect of a significant software preload being loaded and initialized on boot.Ĭonsider balancing CPU, disk performance, and memory capacity. ![]() Understand that disk throughput is critical to on/off performance. Migrate updater processes to use AM to reduce the number of loaded processes. Refrain from enabling hybrid sleep on laptops and ultraportables, because it generates a hiberfile on Standby suspend (S3). Optimize memory consumption to reduce the size of the hiberfile. Understand how memory consumption effects on/off transition times and follow these suggestions: Work with IHVs to leverage Microsoft Store device apps. Use techniques to delay start processes on boot.Ĭonsider converting traditional desktop apps to Microsoft Store apps, which do not cause an impact on boot. When optimizing on/off performance, consider the following suggestions:ĭetermine what non-inbox 1st- or 3rd-party processes are loaded and running on your systems.ĭetermine what is started on boot through registry run keys typically, these are IHV hardware–related processes.Īvoid including managed code processes in the boot path. These processes consume CPU and disk system resources and can result in bottlenecking, which can make the device unresponsive, delay app launch times, or make apps run slowly. Startup apps, such as tray-running shortcuts, OEM status indicators, and so on Fast startup represents about 50% of the overall boot time and is directly affected by the following first- and third-party processes started on boot: The main source of boot delays is the OEM software preload. The considerations in this topic outline the user model for the fast on/off transitions, options related to those transitions, and the components required by OEMs/ODMs to deliver the experience. For information about the improvements made to the performance of the on/off experience, see Hibernate (S4) suspend and resume. The default boot performance has improved dramatically with the leveraging of hibernation technology. In Windows 8.x and Windows 10, this is no longer the case. It was also much easier with slow boot times to create periods of time in which key presses could be detected and activated. In previous releases, it was important to stop the boot process as early as possible for decision points, such as booting to an alternative operating system, because moving backwards was a long and slow process. With a much faster boot time, boot interruptions are impractical and negatively affect the boot experience. Interaction model used previously was to interrupt a boot with key presses to indicate alternate boot paths. Starting with Windows 8.x, the speed of the on/off transition is significantly faster than previous Windows versions. Although connected standby capability reduces the frequency with which a device must be booted, booting might still be required for software and firmware updates, low battery states, and major configuration changes to the device. Customer telemetry tells us that users boot and shut down their PC at least once a day. System boot is the first experience users have with their device and is a recurrent experience for the lifetime of the device. Depending on usage patterns and the battery life capability of the device, a PC might shut down, sleep, or hibernate. ![]() PCs can be turned on and off many times a day. This section provides an overview of the fast startup experience and our recommendations to partners to deliver the best on/off experience for customers. ![]()
