Hi
I am going to explain who you can shutdown your computer using a simple DOS command in particular time span

Example: just Type shutdown -s -t 7200 -c "shutting down in 120 mins, please type 'shutdown -a' in a command prompt to cancel" -f in DOS promt or in RUN of Windowa

You have to mention time limt in seconds as I av mention 7200 sec in above example in above example .This command is helpful when we forget to shutdown when fell asleep while working with system during late night and when the system is unattended for long time,

That will shut down the comp in 120 minutes and force programs to close. You can also make a shortcut to the command prompt and have them on the desktop

If you want more commnad realated to Shutdown just type Shutdown/? in DOS command

Few people use PIN locking system to lock their phone to avoid un-authorised access. Though this is a good option, it pisses you off sometime. Three wrong entry of PIN code will result in SIM blocking. Once SIM gets blocked, phone starts asking PUK code to enter. If you again enter wrong code for three times, SIM gets completely blocked. You have to walk into your service provider outlet to get a replacement SIM card.

PUK code is a SIM specific code assigned by your service provider. No way you can guess & enter it. So, when it asks for the PUK code, don’t do anything, get the PUK code from your service provider. Airtel has a easier way of getting PUK code. For getting PUK code of a Airtel number, send PUKPhoneNumber to toll free number 121. You can make use of any other Airtel number to send this message since your SIM might have been blocked already.

If the above method doesn’t works or your service provider is not Airtel, call to customer care using any other mobile phone which uses the same service provider. They will ask some details about you to make sure you are the owner of the SIM card. Questions might include your billing address, email ID, numbers you recently called or messaged etc. They might even ask you number printed on the SIM card, so be prepared with all details before calling them. Once you get the PUK code, enter it into the phone & your phone will return to normal.

There are plenty of free SMS providers on the internet today. But the problem with these providers is they allow you to use only 140 characters & fill remaining space with ads. It looks so unusual to put ads inside personal messages we are sending! SMSFame is the first website I know which allows users to send free 160 character SMSs. SMSFame relies on online advertising rather than placing ads inside SMS. SMSFame requirs a simple registration process before you start sending SMS. visit www.smsfame.com

Recently, from almost a month SMSs from Banks, Service Providers, Companies have started prefixing something like ID, AT, VK…etc. What’s all this after all!!? Here I am to explain you what it is! Normally these SMSs originates from a Bulk SMS provider where you can use 11 digit Alpha-Numeric characters as "Sender". But there were some security risks in this method. I was able to give a phone number as "Sender" & it appears as that person at the recipient end. Basically there was a chance to send SMSs as a different person! I was actually using this to fool my friends.

But the new TRAI regulation insisted bulk SMS providers to restrict the "Sender ID" to 8 characters. Other three characters should be used to specify who is the service provider & where it’s originated from. Say for example: HDFCBANK sends an SMS to you using bulk SMS provider located at Tamil Nadu which uses Airtel. You will receive it as AT-HDFCBANK. First character specifies which service provider the message is being originated & the second character specifies from which location it’s originated. Here is the table which has details of these SMS codes:

Service Provider Codes:

Service Provider	Code
Aircel, Dishnet Wireless	D
Bharti Airtel	A
BSNL	B
BPL Mobile/Loop Telecom	L
Datacom Solutions	C
HFCL Infotel	H
Idea Cellular	I
MTNL	M
Reliance Communications	R
Reliance Telecom	E
S tel	S
Shyam Telecom	Y
Spice Telecom	P
Swan Telecom	W
Tata Teleservices	T
Unitech Group	U
Vodafone Group	V

Service Area	Code
Andhra Pradesh	A
Assam	S
Bihar	B
Delhi	D
Gujarat	G
Haryana	H
Himachal Pradesh	I
Jammu & Kashmir	J
Karnataka	X
Kerala	L
Kolkata	K
Madhya Pradesh	Y
Maharashtra	Z
Mumbai	M
North East	N
Orissa	O
Punjab	P
Rajasthan	R
Tamil Nadu	T
UP-East	E
UP-West	W
West Bengal	V

So, combination of these two constitutes the first two digit of ?Sender? followed by an hyphen (-) & actual sender name.

We’re still all eagerly awaiting the release of Windows 7, yet Microsoft is officially already working on Windows 8. Two recent job postings indicate the next operating system will be much-improved in many areas and due for release in 2012. Are you excited yet?

It feels like we’ve been waiting for Windows 7 for ages now. We haven’t, it’s only been two-and-a-half years since Vista arrived. Maybe that’s why it feels like a lifetime, because Vista was so damn disappointing and many people haven’t given it the credit it now deserves.

It looks as though Windows 7 is finally finished though. The Release Candidate has already leaked on torrent sites, and the official version is due around May 5. So let’s forget it and focus on the next-but-one Microsoft OS, Windows 8. It’s coming, and probably sooner than most people would expect.

According to ZDNet, Microsoft is already hiring developers specifically to work on Windows 8, despite Windows 7 not yet being out the door. Job postings from April 14 and April 16 seek people for “cluster support and support for one-way replication,” and “the next version of [File Server Management].”

Job postings mentioning Windows 8 have been spotted as far back as 2007 but these are the first which actually mention specific roles and define what element of the future OS an applicant would be working on.

Windows 8 could be with us as early as 2011 although Microsoft is officially claiming 2012 as more likely. As with Vista to Windows 7, this 3-year development plan will likely change depending on how the preceding product is received and how well it ages.

With the increase in use of cloud computing, there has been speculation that Windows 7 will be the last major traditional OS Microsoft releases. But it seems not. Despite looking like having a complete overhaul of the filing system, little is known about what form Windows 8 will ultimately take. It could be just an extension of Windows 7, a leap forward in operating systems, or something straddling the cloud computing service role.

What do you think? What would you like to see in Windows 8? Do you really not care right now, at least until Windows 7 is released and installed on your PC?

Windows 7 (formerly codenamed Blackcomb and Vienna) is an upcoming version of Microsoft Windows, a series of operating systems produced by Microsoft for use on personal computers, including home and business desktops, laptops, tablet PCs, netbooks and media center PCs.^[1] Microsoft has stated that it plans to release Windows 7, "in time for the holiday season" of 2009,^[2] less than three years after the general availability of its predecessor, Windows Vista. Its server counterpart, Windows Server 2008 R2, is slated for release around the same time.

Unlike its predecessor, Windows 7 is intended to be an incremental upgrade to the Windows line, with the goal of being compatible with applications and hardware with which Windows Vista is already compatible.^[3] Presentations given by the company in 2008 have focused on multi-touch support, a redesigned Windows Shell with a new taskbar, a home networking system called HomeGroup,^[4] and performance improvements. Some applications that have been included with prior releases of Microsoft Windows, including Windows Calendar, Windows Mail, Windows Movie Maker, Windows Photo Gallery, will not be included in Windows 7; some will instead be offered separately as part of the freeware Windows Live Essentials suite.^[5]

New and changed features

Main article: Features new to Windows 7

Windows 7 includes a number of new features, such as advances in touch and handwriting recognition, support for virtual hard disks, improved performance on multi-core processors,^{[29][30][31][32]} improved boot performance, and kernel improvements. Windows 7 adds support for systems using multiple heterogeneous graphics cards from different vendors (Heterogeneous Multi-adapter), a new version of Windows Media Center,^[33] a Gadget for Windows Media Center, improved media features, the XPS Essentials Pack and Windows PowerShell being included, and a redesigned Calculator with multiline capabilities including Programmer and Statistics modes along with unit conversion. Many new items have been added to the Control Panel, including ClearType Text Tuner, Display Color Calibration Wizard, Gadgets, Recovery, Troubleshooting, Workspaces Center, Location and Other Sensors, Credential Manager, Biometric Devices, System Icons, and Display.^[34] Windows Security Center has been renamed to Windows Action Center (Windows Health Center and Windows Solution Center in earlier builds) which encompasses both security and maintenance of the computer.

The taskbar has seen the biggest visual changes, where the Quick Launch toolbar has been replaced with pinning applications to the taskbar. Buttons for pinned applications are integrated with the task buttons. These buttons also enable the Jump Lists feature to allow easy access to common tasks.^[35] The revamped taskbar also allows the reordering of taskbar buttons. To the far right of the system clock is a small rectangular button that serves as the Show desktop icon. This button is part of the new feature in Windows 7 called Aero Peek. Hovering over this button makes all visible windows transparent for a quick look at the desktop.^[36] In touch-enabled displays such as touch screens, tablet PCs etc, this button is slightly wider to accommodate being pressed with a finger.^[37] Clicking this button minimizes all windows, and clicking it a second time restores them. Additionally, when a user drags a window to the edge of the screen, it will snap in place on that half of the screen. This allows users to snap documents or files on either side of the screen to compare them. There is also a feature that when a user pulls a window to the top of the screen, it automatically maximizes. When a user moves windows that are maximized, the system restores them automatically.

This functionality is also accomplished with keyboard shortcuts. Holding down the Windows key and pressing the up arrow maximizes; pressing down the down arrow minimizes; pressing the left or right arrows snap the windows to the sides of the screen. Repeating the keyboard shortcuts generally restores the window's previous size. Unlike in Windows Vista, window borders and the taskbar do not turn opaque when a window is maximized with Windows Aero applied. Instead they remain transparent. For developers, Windows 7 includes a new networking API with support for building SOAP based web services in native code (as opposed to .NET based WCF web services),^[38] new features to shorten application install times, reduced UAC prompts, simplified development of installation packages,^[39] and improved globalization support through a new Extended Linguistic Services API.^[40] At WinHEC 2008 Microsoft announced that color depths of 30-bit and 48-bit would be supported in Windows 7 along with the wide color gamut scRGB (which for HDMI 1.3 can be converted and output as xvYCC). The video modes supported in Windows 7 are 16-bit sRGB, 24-bit sRGB, 30-bit sRGB, 30-bit with extended color gamut sRGB, and 48-bit scRGB.^[41][42] Microsoft is also implementing better support for Solid State Drives ^[43] and Windows 7 will be able to identify a Solid State Drive uniquely.

Internet Spades, Internet Backgammon and Internet Checkers, which were removed from Windows Vista, were restored in Windows 7. Windows 7 will include Internet Explorer 8 and Windows Media Player 12.

Users will also be able to disable many more Windows components than was possible in Windows Vista. New additions to this list of components include Internet Explorer 8, Windows Media Player, Windows Media Center, Windows Search, and the Windows Gadget Platform.^[44] Windows 7 includes 13 additional sound schemes, entitled Afternoon, Calligraphy, Characters, Cityscape, delta, Festival, Garden, Heritage, Landscape, Quirky, Raga, Savanna, and Sonata.^[45] A new version of Virtual PC, Windows Virtual PC Beta is available for Windows 7 Professional, Enterprise, and Ultimate editions.^[46] It allows multiple Windows environments, including Windows XP Mode, to run on the same machine, requiring the use of Intel VT-x or AMD-V. Windows XP Mode runs Windows XP in a virtual machine and redirects displayed applications running in Windows XP to the Windows 7 desktop.^[47]

Removed features

Main article: Features removed from Windows 7

A number of capabilities and certain programs that were a part of Windows Vista are no longer present or have changed, resulting in the removal of certain functionality. Some notable Windows Vista features and components have been replaced or removed in Windows 7, including the classic Start Menu user interface, Windows Ultimate Extras, InkBall, and Windows Calendar. Windows Photo Gallery, Windows Movie Maker, and Windows Mail have been removed from Windows itself, but they are available in a separate package called Windows Live Essentials.
