Enable and Disable Fast Startup Mode
on Windows

Does this mode really reduce the time of Windows startup? How can I enable it?

Fast Startup function, also called as Hybrid Boot or Hybrid Shutdown, was introduced already on Windows 8 OS. It allows users to shorten the time of startup. In other words, this feature compresses the entire startup process into one specific hiberfil.sys file. With the help of this command, it reduces system initialization procedure. The latter needs to fully load drivers and services to allow the user to use all system features. In the case of Fast Startup or Hybrid Boot, the file is read which results in faster drivers initialization processes. In overall, if your computer requires several minutes to load, when Fast Startup is enabled, the process takes up to one or two minutes. In short, Fast Startup reloads Windows core drivers and previously save system state faster. It refreshes system files ad RAM. However, there are also drawbacks to this function. In some devices, this function may cause problems resuming the computer from the sleep mode. Certainly, it may be the result of several coinciding factors. Secondly, this function may not fully compatible with encrypted disk images. Especially, it applies users who use password encrypting programs. Mounting encrypted drivers before rebooting the system may result in automatic remounting after the restart. Thirdly, this function may interfere with performing system updates thoroughly. This feature is crucial taking into account not only the efficiency of the system but virus activity as well. Thus, you should weigh pros and cons before enabling this feature. Here, we present a few options how to enable/disable Fast Startup:
