Hibernation : Hibernate is a feature of many computer operating systems where the contents of RAM are written to non-volatile storage such as a hard disk, as a file or on a separate partition, before powering off the computer. When the computer is restarted it reloads the content of memory and is restored to the state it was in when hibernation was invoked. Hibernating and later restarting is usually faster than closing down, later starting up, and starting all the programs that were running. Going into hibernation requires no user interaction; shutting down when programs are open either requires programs to be closed properly, or user interaction to force them to close, with possible loss of data.

While starting from a hibernated state is usually quicker than starting up and opening all applications, it still requires a few seconds or more, depending on the system's general speed.

To enable hibernation the hard disk must have sufficient free space to store all non-replaceable contents of RAM.

In some cases entering into hibernation can cause incorrect operation on restarting, due to problems with the hibernation software, or with devices or software which is not fully compliant. Hibernate causes connections to other devices to terminate.

If you don’t use the Hibernate option in Windows 7, you can save some disk space by disabling it. Here we will look at a few different ways to manage hibernate options in Windows 7.

Note: Hibernate mode is not an option on systems with 4GB of RAM or more.

Enable or Disable Hibernate Through Command Prompt

Using the Command Prompt might be the easiest way to enable or disable Hibernation. Click on Start and type CMD into the search box and it will be listed under programs. Right-click on the icon and select Run as administrator.



The Command Prompt opens and you will use the following to enable Hibernation.

powercfg /hibernate on



Type in the following to disable hibernation.

powercfg /hibernate off



Manage Hibernation Through Control Panel

Click on Start and open Control Panel then click on Power Options.



On the left side click on Change when the computer sleeps.

Now click on Change advanced power settings.




In the Advanced Power Options window expand the Sleep tree then expand Hibernate after and change the minutes to zero to turn it off. Or you can specify the amount of minutes you want to pass before it goes into hibernation. After you’ve made your selection click Apply and Ok then close out of the remaining screens.



Where is Hibernate option?

What if you try the command line option to turn it on and Hibernate mode still isn’t available? Then what you’ll want to do is disable Hybrid Sleep by expanding Allow hybrid sleep and turning it Off.



Now you should have Hibernate and Sleep as part of the power options in the start menu and will also be an option when you hit Ctrl+Alt+Del.




Enable/Disable Hibernate Through Regedit

Note: Changing registry values can cause your computer to become unstable or stop functioning and is only recommended for experienced users.

Now that the disclaimer is out of the way…you might want to completely disable Hibernate mode through a registry edit. Open the Registry and browse to HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Power and change both HiberFileSizePercent and HibernateEnabled value data to zero to disable it and 60 to enable it. After you’ve made the changes close out of the Registry Editor and restart the machine.



If you always turn off your computer or never do, you can disable the Hibernate mode to gain a bit of extra hard disk space. On our Windows 7 (32-bit) machine with a 300GB hard drive, disabling Hibernation gained us just over 3GB of more disk space. That may not seem like much especially with today’s high capacity drives, but if you don’t need Hibernation, why not reclaim that space?

One of the biggest annoyances with a dual-boot system is having to wait for your PC to reboot to select the operating system you want to switch to, but there’s a simple piece of software that can make this process easier.



With a small piece of software called iReboot we can skip the above step all together and instantly reboot into the operating system we want right from Windows. Their description says:
“Instead of pressing restart, waiting for Windows to shut down, waiting for your BIOS to post, then selecting the operating system you want to boot into (within the bootloader time-limit!); you just select that entry from iReboot and let it do the rest!”
Don’t worry about iReboot reconfiguring  your bootloader or any dual boot configuration you have. iReboot will only boot the selected operating system once and go back to your default settings.


Using iReboot : download
iReboot is quick and easy to install. Just download it, link below, run through the setup and select the default configuration. iReboot will automatically figure out what operating systems you have installed and appear in the taskbar. Go over to the taskbar and right click on the iReboot icon and select which operating system you want to reboot into.



This method will add a check mark on the operating system you want to boot into.
On your next reboot the system will automatically load your choice and skip the Windows Boot Manager. If you want to reboot automatically just select “Reboot on Selection” in the iReboot menu.
To be even more productive, you can install iReboot into each Windows operating system to quickly access the others with a few simple clicks.
iReboot does not work in Linux so you will have to reboot manually.Then wait for the Windows Boot Manager to load and select your operating system.
iReboot works on Windows XP, Windows Vista, and Windows 7 as well as 64 bit versions of these operating systems. Unfortunately iReboot is only available for Windows but you can still use its functionality in Windows to quickly boot up your Linux machine. A simple reboot in Linux will take you back to Windows Boot Manager.

In a recent interview, Steven Sinofsky, president, Windows and Windows Live Division noted that there simply was no way of telling how Microsoft would be able to outdo Windows 7 with the forthcoming Windows 8. And yet, a Program Manager on the Windows team, working on Windows Update, published a blog post in which he enthusiastly promised that Windows 8 would end up being completely different  than everything customers expected of a Windows release. While it offered no actual details on the next iteration of Windows, the PM managed to shed light on the enthusiasm that was undoubtedly fueling the people behind the Windows project, as Windows 7 was a smashing success, with over 60 million sold licenses since launch.

Today i am going to discuss some well known Windows Tweaking applications just to make windows as fast as as a new one. I have tested a lot of applications and chose 3 of them for this post. They are Advanced System Care , Tuneup Utilities and Registry Mechanic. These applications will help you maintain your PC to the core. These will help your defrag registry boosting perfromance, cleaning up junk file to recover Hard drive space , remove spyware and prevent them from getting back again to your pc , customizing your windows looks , cleaning your brwosing traces etc. So lets watch thme working one by one :-

VMware, Inc. is a provider of virtualization software.The company was founded in 1998 and is based in Palo Alto, California.The Company is majority owned by EMC Corporation .VMware's desktop software runs on Microsoft Windows, Linux, and Mac OS X.VMware's enterprise software, VMware ESX Server, runs directly on server hardware without requiring an additional underlying operating system.Founded in 1998 , this enterprise today produces best virtualisation solution for desktops and servers.VMware software provides a completely virtualized set of hardware to the guest operating system.VMware software virtualizes the hardware for a video adapter, a network adapter, and hard disk adapters.The host provides pass-through drivers for guest USB, serial, and parallel devices.
In this way, VMware virtual machines become highly portable between computers, because every host looks nearly identical to the guest.
In practice, a system administrator can pause operations on a virtual machine guest, move or copy that guest to another physical computer, and there resume execution exactly at the point of suspension.
Alternately, for enterprise servers, a feature called VMotion allows the migration of operational guest virtual machines between similar but separate hardware hosts sharing the same storage.
Each of these transitions is completely transparent to any users on the virtual machine at the time it is being migrated.VMware's products use the CPU to run code directly whenever possible .
When direct execution cannot operate, such as with kernel-level and real-mode code, VMware products re-write the code dynamically, a process VMware calls "binary translation" or BT. The translated code gets stored in spare memory, typically at the end of the address space, which segmentation mechanisms can protect and make invisible. For these reasons, VMware operates dramatically faster than emulators, running at more than 80% of the speed that the virtual guest operating-system would run directly on the same hardware.

Basically for desktop theere are 5 products of VMware :
*VMware Fusion
*VMware Workstation
*VMware View
*VMware Player
*VMware ACE

I have been looking forward for a replacement of Vitualbox OSE . This thing started our quest for finding a Visualization application to fulfill the needs with an easy-to-use procedure. I found KVM in Add/remove while i was looking for something alike YaVM - Yet another Virtual Machine (An application developed for openSUSE in 2006 to serve as basic virtual machine that comes with the os preinstalled). Xen , the geeky Virtual machine by SUSE linux enterprise is a virtualisation powerhouse. While Xen offers quite complex procedure requiring you to boot a patched Xen kernel to create and run a Virtual machine - KVM is a loadable module which runs with the OS's default kernel module. The only thing it requires is that your processor should have the architecture to support virtualisation .

For this type:

kvm

in the terminal and see the result:

QEMU PC emulator version 0.9.1 (kvm-84), Copyright (c) 2003-2008 Fabrice Bellard
usage: qemu [options] [disk_image]

If you see the above message, then you should be smiling as you are green to go for virtualisation with your hardware.

But if your CPU does not, in fact support Hardware virutalization, you will get output such as the following:

$ kvm
Could not initialize KVM, will disable KVM support
Ubuntu does not support running KVM without hardware acceleration. Sorry.

So lets start our work with Virtualisation weapons at hand. First, head on over to the KVM HOME PAGE :

http://www.linux-kvm.org/page/Main_Page

Best feature of KVM is that it is part of the OS and is not dependent upon a 3rd party vendor . Also, it’s very easy to maintain as you update your system, and load new kernel revisions, as the module will not break like VirtualBox and VMware solutions would. Also, it’s far less problematic to manage than Xen, which is entirely unsuitable for a desktop system IMO :P . KVM really is more of a direct competitor to Xen than to a workstation solution like VirtualBox or VMware workstation, and has some very powerful features, I will never tap into here on my home system. By design however, it’s far less intrusive on a standard Linux desktop than Xen.

Now we have our kernel module working properly and rest everything in place so must get back to bussiness :D. I will use Lubuntu for the testing purpose coz its my personnel favourite and it very light too.

Follow these steps to set up your virtual Machine :-

Step I : Launch :- Goto Applications>System tools and start KVM . Then choose the virtualisaton method to full virtualisation if your processor supports that feature.





Step II :Installation Method :- Now choose the media from which the OS is to be installed to the machine . Also chose the OS type and its Variant .




Step III : Installation Media : Select he ISO image location (whether from External drive or already present image from HDD) .



Step IV :Allocating Space:- Choose the disk space you wnt to allocate to the machine's Virtual Hard drive. Allocate space wisely for stability issues .Then select to allocate the whole virtual hard disk to the machine .


Note: If you dont allocate the whole virtual hdd to the machine , then the machine will allocate space for itself while it is running and if the space in that partition goes out , the the data in the virtual machine is likely to get corrupted. You can allocate additional space like network drives etc to your virtual drive.

Step V : Memory &  CPU allocation :- Allocate RAM for your machine which it wil be able to utilize to max. You have to allocate RAM for peak run and startup diffrently. Do it generously for proper running of he host and virtual machine . Eg: i have 2 gb RAM and i allocated 750 mb to the machine to max and for start-up , i gave it 512 mb. You can change the se settings in the hardware section og the gui while running the machine.



Step VI : Finishing Job :- Check your preferences and Click finish & let the magic happen. The installation os a virtual OS is totally same as installing a regular OS. So, now we are done with it .



Obviously , KVM is much more capable than we discussed just now. We were just able to do the basics, rest you can try on your own after installing the application.


Happy Virtualistion !!!
