How to disable and re-enable hibernation on a computer that is running Windows Vista

INTRODUCTION

This article describes how to disable and re-enable hibernation on a computer that is running Windows Vista.

Warning You may lose data if you make hibernation unavailable when the hybrid sleep setting on the computer is turned on, and a power loss occurs. When you make hibernation unavailable, hybrid sleep does not work.

MORE INFORMATION

The Hiberfil.sys hidden system file is located in the root folder of the drive where the operating system is installed. The Windows Kernel Power Manager reserves this file when you install Microsoft Windows. The size of this file is approximately equal to the amount of random access memory (RAM) that is installed on the computer.

The computer uses the Hiberfil.sys file to store a copy of the system memory on the hard disk when the hybrid sleep setting is turned on. If this file is not present, the computer cannot hibernate.

Hibernation is made unavailable when you set the value of the Hibernate after setting to Never by using the Power Options item in Control Panel. To make hibernation unavailable, follow these steps:

1.	Click Start, and then type cmd in the Start Search box.
2.	In the search results list, right-click Command Prompt, and then click Run as Administrator.
3.	When you are prompted by User Account Control, click Continue.
4.	At the command prompt, type powercfg.exe /hibernate off, and then press ENTER.
5.	Type exit, and then press ENTER.

Windows Vienna / Windows 7

Windows 7 (formerly codenamed Blackcomb, then Vienna) is a future version of Microsoft Windows. It is expected to be the successor to Windows Vista. Microsoft has confirmed that the planned development time frame is at least three years, putting the release date around 2010. On July 20, 2007, Microsoft confirmed that Windows 7 is "the internal name for the next version of the Windows Client OS".Microsoft has refrained from discussing the details about Windows 7 publicly as they focus on the release and marketing of Windows Vista, though some early details of various core operating system features have emerged at developer conferences such as Windows Hardware Engineering Conference in 2006.


Focus
On February 9, 2007, Microsoft's Ben Fathi claimed that the focus on the operating system was still being worked out, and could merely hint at some possibilities: “ We're going to look at a fundamental piece of enabling technology. Maybe it's hypervisors. I don't know what it is" [...] "Maybe it's a new user interface paradigm for consumers.” Bill Gates, in an interview with Newsweek, also suggested that the next version of Windows would "be more user-centric." When asked to clarify what he meant, Gates said: “That means that right now when you move from one PC to another, you've got to install apps on each one, do upgrades on each one. Moving information between them is very painful. We can use Live Services to know what you're interested in. So even if you drop by a [public] kiosk or somebody else's PC, we can bring down your home page, your files, your fonts, your favorites and those things. So that's kind of the user-centric thing that Live Services can enable. [Also,] in Vista, things got a lot bet er with [digital] ink and speech, but by the next release there will be a much bigger bet. Students won't need textbooks; they can just use these tablet devices. Parallel computing is pretty important for the next release. We'll make it so that a lot of the high-level graphics will be just built into the operating system. So we've got a pretty good outline.

Features
Microsoft is maintaining a policy of silence concerning plans and aspirations for Windows 7. As a result, very little is known about the feature set. However, from interviews and speeches of company executives certain features have been known.

Availability
The client versions of Windows 7 will ship in both 32-bit and 64-bit versions.Server versions of Windows 7, however, will be exclusively 64-bit.
