powercfg must be run from an elevated command prompt, and, under Windows XP, it requires workstation Administrator or power user rights. Power Schemes are configured on a per-user basis. The most common cause of problems with power saving and hibernation on Windows systems is an incompatible device driver.
The File Types tab has been removed from Folder Options. This feature was available from Windows 95 up to Windows XP and Windows Server 2003. The File Types tab allowed users to change the file associations for various types of files. It allowed configuring which application would open when a user clicked on a certain type of file, or allowed ...
Windows Vista introduced a hybrid sleep feature, which saves the contents of memory to hard disk but instead of powering down, enters sleep mode. If the power is lost, the computer can resume as if hibernated. Windows 7 introduced compression to the hibernation file and set the default size to 75% of the total physical memory. [18]
This approach combines the benefits of sleep mode and hibernation: The machine can resume instantaneously, but it can also be powered down completely (e.g. due to loss of power) without loss of data, because it is already effectively in a state of hibernation. This mode is called "hybrid sleep" in Microsoft Windows other than Windows XP.
Advanced Configuration and Power Interface (ACPI) is an open standard that operating systems can use to discover and configure computer hardware components, to perform power management (e.g. putting unused hardware components to sleep), auto configuration (e.g. Plug and Play and hot swapping), and status monitoring.
The status bar no longer shows the free space remaining on the given disk when browsing through folder paths of shell namespace extensions, [13] removable drives, [14] and network shares when the navigation pane (Folders) in Windows Explorer is turned on, unlike in Windows 2000. It continues to show the free space remaining only for paths on ...

By default, Windows 7 automatically sets the size of the hibernation file to 75% of a computer's total physical memory. The operating system also compresses the contents of memory during the hibernate process to minimize the possibility that the contents exceeds the default size of the hibernation file. [54]
