At Google, we spend much of our time working inside a browser. We search, chat, email and collaborate in a browser. And like all of you, in our spare time, we shop, bank, read news and keep in touch with friends - all using a browser. People are spending an increasing amount of time online, and they're doing things never imagined when the web first appeared about 15 years ago.
Since we spend so much time online, we began seriously thinking about what kind of browser could exist if you started from scratch and built on the best elements out there. We realized that the web had evolved from mainly simple text pages to rich, interactive applications and that we needed to completely rethink the browser. What we really needed was not just a browser, but also a modern platform for web pages and applications, and that's what we set out to build.
So today we're releasing the beta version of a new open source browser: Google Chrome.
On the surface, we designed a browser window that is streamlined and simple. To most people, it isn't the browser that matters. It's only a tool to run the important stuff - the pages, sites and applications that make up the web. Like the classic Google homepage, Google Chrome is clean and fast. It gets out of your way and gets you where you want to go.
Under the hood, we were able to build the foundation of a browser that runs today's complex web applications much better . By keeping each tab in an isolated "sandbox", we were able to prevent one tab from crashing another and provide improved protection from rogue sites. We improved speed and responsiveness across the board. We also built V8, a more powerful JavaScript engine, to power the next generation of web applications that aren't even possible in today's browsers.
This is just the beginning - Google Chrome is far from done. We've released this beta for Windows to start the broader discussion and hear from you as quickly as possible. We're hard at work building versions for Mac and Linux too, and we'll continue to make it even faster and more robust.
We owe a great debt to many open source projects, and we're committed to continuing on their path. We've used components from Apple's WebKit and Mozilla's Firefox, among others - and in that spirit, we are making all of our code open source as well. We hope to collaborate with the entire community to help drive the web forward.
The web gets better with more options and innovation. Google Chrome is another option, and we hope it contributes to making the web even better.
But enough from us. The best test of Google Chrome is to try it yourself.

Internet Explorer 8 Features
Has tried Internet Explorer 7? or at the time was to switch to Internet Explorer 8. For some people, not many knows the difference between IE 7 and IE 8 and what you can do with IE 8. Here are some of the features available in IE 8, you can distinguish yourself with IE 7
How many steps does it take with your current browser to map an address, translate a word, or perform other routine tasks online? Until now it was likely a series of cutting and pasting information from one webpage to another. Now there's a better way. The new Accelerators in Internet Explorer 8 help you quickly perform your everyday browsing tasks without navigating to other websites to get things done. Simply highlight text from any webpage, and then click on the blue Accelerator icon that appears above your selection to obtain driving directions, translate and define words, email content to others, search with ease, and more. For example, with the "Map with Live Search" Accelerator in Internet Explorer 8, you can get an in-place view of a map displayed directly on the page.
You can discover other useful Accelerators by selecting the More Accelerators option on the right-click menu, or visit our Accelerators gallery. You can easily delete, disable, or enable Accelerators by clicking on Manage Add-ons from the Tools button on the upper right-hand corner of your browser window.
Internet Explorer 8 includes a number of useful Accelerators to get you started. Simply highlight text from any webpage, and then click on the blue Accelerator icon The Accelerator icon that appears above your selection to get things done faster than ever. You can add more by going to the Internet Explorer Gallery to customize the browser with Accelerators from Live Search, eBay, Yahoo!, Wikipedia, Amazon, Facebook, and other sites in a way that works for you.
Have you ever forgotten the complete title of a book you were hoping to find or the first name of the actor in last night's movie? The new search capabilities in Internet Explorer 8 will offer relevant suggestions as you type words into the search box to help save time. Click on a suggestion at any time to immediately execute the search without having to type the entire word or phrase.
Internet Explorer 8 is partnering with top search providers like Live Search, Wikipedia, Yahoo!, Amazon, and more to deliver visual suggestions that provide you with immediate answers. For example, typing "Isaac Newt" with Wikipedia visual suggestions will instantly show you a preview of the results directly in the Search Box drop-down. Look for more visual suggestion results with your preferred search providers.
Internet Explorer 8 includes a completely redesigned Find On Page toolbar, which is activated by pressing Ctrl-F or choosing Find On Page from the Edit menu or Search box drop-down. Press the Alt key if you do not see the Edit menu option.
The toolbar is integrated below the tab row, so that it does not obscure any content on the page. Instead of waiting for you to type an entire search term and hit Enter, the toolbar searches character-by-character as you type. Matches are highlighted in yellow on the page so that they're easy to identify.
Internet Explorer 8 includes many performance improvements that contribute to a faster, more responsive web browsing experience in the areas that matter most. Internet Explorer 8 starts quickly, loads pages fast and instantly gets you started on what you want to do next by using a powerful new tab page. In addition, the script engine in Internet Explorer 8 is significantly faster than in previous versions, minimizing the load time for webpages based on JavaScript or Asynchronous JavaScript and XML (AJAX).
See how Internet Explorer 8 stacks up against other popular browsers in real world benchmark testing.
Want to take a deeper dive into the performance improvements in Internet Explorer 8? Download this whitepaper for all the details.
Can't remember the full address of a new website you visited last week? Type a few characters in the new Address Bar and Internet Explorer 8 will automatically recall sites you've already visited based on your entry. It searches across your History, Favorites, and RSS Feeds, displaying matches from the website address or any part of the URL. As you type, matched characters are highlighted in blue so you can identify them at a glance. In addition, you can delete any address in the drop-down box by clicking on the red X. This is especially useful for getting rid of misspelled URLs.
Microsoft Launch Hardware features for Windows 7
Labels: WindowsREDMOND, Wash. --June 2, 2009-- Microsoft Hardware today announced that its current line of award-winning mice, keyboards, LifeCams, gaming devices and notebook accessories will be fully compatible with Windows 7 once the operating system is launched to retail customers on Oct. 22, 2009.1 Making everyday tasks faster and easier, Microsoft Hardware created new, timesaving features for Windows 7 to ensure that anyone using the new operating system gets a better experience.
Microsoft Hardware will launch several new features for Windows 7 in the coming months for its peripherals; the first of which is a timesaving feature called Taskbar Favorites that gives Microsoft keyboard users a smart new way to access their most frequently used programs and documents. Taskbar Favorites will map to the location of applications on the improved Windows taskbar. The applications in the taskbar can be easily rearranged just by clicking and dragging, and Taskbar Favorites will automatically adapt to the applications’ new locations. Additional new benefits of the Microsoft Hardware and Windows 7 connection include the following:

Windows 7 Keyboard Shortcuts
Congratulations to you who have been using Windows 7. many people say "I will not go back again to the vista." If you're one of them?
we will try to provide tips & tricks keyboard shortcuts make it easier for you to understand and explore the facilities provided by windows 7
Here is a quick summary of what I’ve found so far for Windows 7:
Window Management
Taskbar
Windows Explorer
(The additional Open options only appear for folders but the “Copy as path” option appears for both folders and files.)
Miscellaneous
15 things you need to know about Windows 7
Labels: WindowsWindows 7 has been making headlines for a few months now. If you've read one or two of the stories and reviews dedicated to it, you might think that you know about all that it contains: new touchscreen features, a revamped taskbar with larger thumbnail previews, Internet Explorer 8, easier networking and so on.
While that sounds reasonable enough, it's not exactly exciting. It might even have given you the impression that Windows 7 isn't very different from Vista. That assumption, however, would be a mistake.
The reality is that Windows 7 is packed with new developments – it's just that most people aren't talking about them.
Would you like to be able to defrag multiple hard drives at the same time, or create a sandboxed PC user account for your kids so that they won't be able to mess up your Windows or program settings any more?
What about working with – and even booting from – virtual hard drive (VHD) files, the ability to encrypt USB flash drives to protect the data you're carrying, and tools for calibrating your display to ensure that you're seeing accurate colours and crisp, clear text? Windows 7 has all these features, and a whole lot more.
Security
1. Keep your PC clean
If you share your PC with less experienced computer users then you'll know the problems that can arise as they mess up your settings and unknowingly install dodgy software. Windows 7 can help you to avoid these problems.
Enable PC Safeguard on the kids' account and they'll be able to log on and play as normal – but when they log off , any settings they've changed are reversed, files they've saved are deleted and your hard drive is returned to its original state.
2. Restrict other users
If Safeguard isn't enough, try AppLocker. It gives you even more control, restricting users to only the programs you specify. It's able to automatically create rules for your installed programs, and other rules can be added in seconds.
3. Action Center
Windows 7 replaces the Security Center with the more all-purpose Action Center, which warns you of PC maintenance and back-up issues as well as potential security problems. It's prone to complaining if your security settings don't meet its approval, but at least now there's an effective solution.
If you regularly see messages telling you that you've turned the Windows firewall off , say, then you can choose to disable just those while leaving the more useful alerts active.
4. Tone down UAC
User Account Control irritated many Windows Vista users with its constant warnings that 'Windows needs your permission to continue'. Windows 7 improves the situation by displaying fewer warnings and providing additional UAC tweaks.
Tell the system not to raise warnings if you change Windows settings and you'll be able to use the Control Panel without any prompts. Alerts will only appear if a program tries to perform a similar action.
5. BitLocker to go
Encryption isn't just for hard drives anymore: the Windows 7 version of BitLocker can protect removable (and easily lost) devices such as USB flash drives, too.
Right-click the device in Explorer, select 'Turn on BitLocker' and then enter and confirm a password to protect your data from snoopers.
6. 'Run as' returns
Right-click a program in Windows XP and you'll see a 'Run as' option that allows you to run the program as a different user. This is very useful if you'd like to run an app that requires different privileges to your current account.
The option disappeared in Vista, but Microsoft has relented: hold down [Shift] while right-clicking a shortcut and you'll see that the 'Run as' option has returned.
7. Find and fix problems
Windows has always had plenty of troubleshooting tools, but they've been scattered around many different places. Windows 7 brings order to this situation by placing all of the most important troubleshooters in the new Find and Fix Problems applet, located in the Control Panel.
These fix common problems, check for incorrect settings, clean up your PC and more. Developers can create additional troubleshooters, too. You can read more about that at Within Windows.
8. The Problem Steps Recorder
As a knowledgeable PC user, it's likely that you're called upon to troubleshoot friends' computer problems, which can be tricky if they find it difficult to describe what's going on. Windows 7 has a handy tool to solve this problem.
If an application is misbehaving under Windows 7, all the flummoxed PC user needs to do is launch the Problem Steps Recorder, click 'Record' and work through whatever task they're trying to complete.
Every click and keypress that they make will be recorded, packaged up with screen grabs and saved into a single zipped MHTML file, ready for emailing to you. It's a simple tool that's going to save many people hours of time.
9. Extended System Restore functionality
System Restore has always been a very handy troubleshooting tool, and Windows 7 extends it in a couple of useful ways. A single click will now tell you exactly which programs and drivers will be restored or deleted if you choose a particular restore point, and there's now an interface that lets you configure the amount of disk space allocated to System Restore.
You can also decide not to back up Windows settings. This means that only files will be backed up, so you'll be able to squeeze more restore points into the available disk space.
10. Discover bottlenecks
If your Windows 7 PC seems sluggish, the new and extended Resource Monitor should help you to sort things out. It's like a more powerful version of Task Manager that not only shows you the processes running on your PC, but also reveals how they're using your CPU, RAM, hard drive and network.
A couple of clicks can show you who the biggest resource hogs really are.
11. DIY system discs
Windows 7 includes a new option to burn a bootable system repair disc. If your PC won't start, pop in the repair disc and it'll do its best to restore normal operations. There's no new technology involved – it's just a CD version of the Start-up Repair tools on your Windows Vista disc – but this functionality will be useful for people who never get a full Windows 7 DVD.
It's also safer to carry one of these around with your laptop rather than risk damaging or losing your original Windows disc.
12. Faster IE startups
Some heavyweight Internet Explorer add-ons can take a while to start. IE8 can help you spot the worst off enders.
Click 'Tools | Manage Add-ons', peruse the Load Time column and you'll immediately see which extensions are putting a brake on your browsing.
13. Simultaneous disk defrags
Ever wondered why you can't defrag both your hard drives at the same time? There's no reason why not – and now in Windows 7 you can through the command-line defrag tool. Other new switches run the defrag at a higher priority and provide regular progress reports. Enter 'defrag /?' in a command-line window to fi nd out more.
14. Multithreaded Robocopies
The command-line Robocopy tool also sees new optimisations, including an '/MT' switch that can improve performance by carrying out multithreaded copies (you can specify up to 128 threads).
Enter 'robocopy/?' at the command line for the full details, though Robocopy newbies should be aware that there are an enormous number of switches to examine.
15. Search connectors
Windows 7 adds support for search connectors. These are small configuration files that extend the Windows Search tool to include online resources. To add Flickr support, for example, visit www.istartedsomething.com/flickr search to download and open the connector.
This will add a Flickr Search option to your Searches folder, and you'll be able to search the site from within Explorer.

What is Operating System?
Before step further, we know first whether it is operating system.Operating system (commonly abbreviated to either OS or O/S) is an interface between hardware and user; it is responsible for the management and coordination of activities and the sharing of the resources of the computer. The operating system acts as a host for applications that are run on the machine. As a host, one of the purposes of an operating system is to handle the details of the operation of the hardware. This relieves application programs from having to manage these details and makes it easier to write applications. Almost all computers, including handheld computers, desktop computers, supercomputers, and even video game consoles, use an operating system of some type. Some of the oldest models may however use an embedded operating system, that may be contained on a compact disk or other data storage device.
Operating systems offer a number of services to application programs and users. Applications access these services through application programming interfaces (APIs) or system calls. By invoking these interfaces, the application can request a service from the operating system, pass parameters, and receive the results of the operation. Users may also interact with the operating system with some kind of software user interface (UI) like typing commands by using command line interface (CLI) or using a graphical user interface (GUI, commonly pronounced “gooey”). For hand-held and desktop computers, the user interface is generally considered part of the operating system. On large multi-user systems like Unix and Unix-like systems, the user interface is generally implemented as an application program that runs outside the operating system. (Whether the user interface should be included as part of the operating system is a point of contention.)
Ubuntu, a Linux based operating system
Common contemporary operating systems include BSD, Darwin (Mac OS X), Linux, SunOS (Solaris/OpenSolaris), and Windows NT (XP/Vista/7). While servers generally run on Unix or some Unix-like operating system, embedded system markets are split amongst several operating systems
