Windows8 Operating system Feauters

Yahooooo……coming soon new windows8 operating system its amazing and fabulous 

hi friends in this post new feature of windoes8 and it's working performance,improvements and its details

There’s something to be said about Microsoft’s next operating system, Windows 8. It will be the first OS developed by Microsoft to cater to the tablet world while simultaneously providing all the new features and expected bugs of a new Windows for PC users. Microsoft seems to be missing one key thing, however, and that’s what people actually want in a tablet.

Walk around your nearest computer store and ask the people looking at tablets what they’re looking for. Odds are, they won’t mention they’re buying an iPad because it has the iOS operating system or any other tablet because it runs Android. Most of them will be looking at things like price and general features. Does the battery last a reasonable amount of time? Is it sturdy? What’s the screen size? Can it access the internet anywhere I go? These are all things outside the realm of the operating system itself. Sure, devices running Android tend to have shorter battery lives, but the average user won’t know that. This is where Microsoft seems to be missing the mark as it isn’t building a device itself, but rather an operating system to run on other devices. Oddly enough, Microsoft should be looking at what makes Apple products so successful if they want to even have a shot at getting in to the tablet market.

What about the PC market? Surely Windows 8 will thrive there. If the new features for Windows 8 actually work well, then yes it should do very well. Not that it will matter as most new PCs will ship with Windows 8 once it is released, but remember that Vista was pretty poorly made and the focus was entirely on PCs. Even after it came out, many people simply went back to Windows XP until Windows 7 came around. Microsoft would do very well not to repeat history with Windows 8, and yet there are signs pointing to at the very least a partial repeat.

Part of what Windows 8 will do is bring the tablet experience to PCs and the PC experience to tablets. That means users could essentially use Microsoft Office on their tablet devices running Windows 8 and have a touch-style interface on their Windows 8 PCs. But therein lies the problem: why use a tablet for PC work and vice versa? As anyone knows, typing on a tablet is annoying. Many tablets have keyboard peripherals which essentially turns them in to very lightweight yet cumbersome laptops. Making a tablet in to a laptop completely defeats the purpose of a tablet, which is to do everything on a computer at the touch of a finger in the most portable way possible. Likewise, PCs have the distinct advantage of a mouse and keyboard. There’s no reason to try making a tablet interface work on a PC because PCs aren’t limited by the small screen sizes and processing power of tablets. Thankfully, Windows 8 can be used more similarly to Windows 7 but whether this is by default on PCs remains to be seen.

Windows Update in Windows 8: No More Headaches?:

Yes, you did read that title right. For the very first time ever, updates in Windows may not be the legendary monsters that tear at you with claws of instantaneous reboots and bite with teeth of annoying pop-ups.

Among other features, Windows 8 is gearing up to improve the updates function. PCs running on Windows 8 will only restart when security updates are installed and require reboots. Thankfully, the aforementioned reboot should only take place about once a month, which won’t do much to hinder your regular PC use. This regular timing will give you a sense of when you should prepare for an update release. Of course, critical updates will be pushed and installed automatically outside of this monthly cycle, but hey: I’d rather spend my time rebooting for a few minutes (we all know how fast Windows 8 is at that) than to be susceptible to a virus going around.

 

One of the best parts about the new Windows Update is that after it has downloaded and installed security updates, you get an entire 3 days to do whatever you need to before a restart. This 72-hour period should be more than enough to save important work, and but it also keeps your computer secure.

 

Last but not least, the updated Windows Update (that was totally intentional) will also offer updates for 3rd party device drivers, with a common set of setup tools for each. All of these updates are carefully screened, and must adhere to the Windows conventions for updates regarding rollback and recovery, and overall system impact.  This means streamlining updates for your PC, mouse, external hard drive, and any other peripherals you may have.

 

Windows 8: Beta Shots?:

Now that the Developer Preview of Windows 8 has been released and the highly anticipated BUILD Conference has passed,Windows8Center is eagerly awaiting the next step in the Windows 8 process: the beta. Finally, we have some real leaks, not the standard Microsoft-authorized “Building Windows 8” blog posts. First up, some pictures from Winunleaked that provide a glimpse into a pre-beta

 version of Windows 8:

In the start screen, users can activate a sort of “zoom out” feature that gives them an overview of their apps(this feature was demonstrated before but not included in the Dev Preview)

Microsoft Details Drastic Memory Improvements In Windows 8:

When Windows 7 was released, Microsoft had set out to erase the bad rap Windows had gotten because of Windows Vista, which was notorious for being a memory hog. And now, with Windows 8, Microsoft is aiming to do the same thing – on devices with even lower system specs than Windows 7 required, especially because of the rise of tablet devices and SoC based devices that are distinguished by low power consumption. Using up RAM (random access memory) also saps power from the device. Therefore, if an operating system uses a lot of memory, then more physical RAM will have to be built into a device, and bam! – less battery life.

Memory Combination: When a program is called, it may allocate memory for future use – but if the user never invokes the function that requires that memory, then it pretty much goes to waste. If multiple applications are doing this, then there will be redundant copies of memory around the system, which is not good for memory efficiency. So what Windows 8 will do is scout for redundant copies, free them up, and keep a single copy. This process can save tens to hundreds of megabytes of memory.

Service Changes and Reductions: Windows has always had a lot of services running in the background that no one has ever really cared for – and so Microsoft has removed some of those, moved some to “manual start” and another group to “start on demand,” which a triggered by some action in the OS, say, perhaps, device arrival, and they execute these steps.

Lazy initiation of the “desktop”: We all know that     Microsoft is intending to bake the familiar appearance of the Windows “desktop” into Windows 8 via system application. So the OS components    that you’ll find   unique to the   desktop application will not be initiated at     people will stay completely inside the Metro UI, startupbecause somewhich saves  memory.       Giving priorities efficiently: Let’s say you’re in Windows 7, opening Excel while you have a bunch of different apps open as well. Let’s also say that you also have antivirus software that checks the files you’re opening for your safety. Well, the specific memory that the antivirus software is allocating to check that one file will probably never be used again. If Windows 7 is low on memory, it may delete memory that helps Excel – even   through the antivirus software is finished and doesn't still need the memorey
Faster Boot Times in Windows 8: Building Windows 8:
A new entry in the “Building Windows 8″ blog has been published, titled “Delivering Fast Boot Times in Windows 8″. He recognizes that boot time is one of the features most discussed about, and says the Windows division wants your boot to be as fast as possible. It comes as a welcome addition to the information that we’ve been given about Windows 8 – Windows 7 and its predecessors seem like lightyears behind Apple products in terms of booting up. I’m sure that everyone reading this post has encountered long periods of frustration as your computer restarts in what seems like an eternity.
He displays this new need for a faster startup time with two graphs
                      

This means that on average on nearly every Windows 7 device (I’m assuming no tablet inclusion) 51% of all power transitions are shutting down, which really outlines the importance of improving this feature
Their solution?
A new hybrid combination of the tradition  cold bootup and resuming from hibernate

An explanation of shutting down and boot, worded excellently by Mr. Sinofsky, is in order:
The user initiates a shutdown by selecting “shut down” from the Start menu, or by pressing the power button; or an application initiates shutdown by calling an API such as ExitWindowsEx() or InitiateShutdown().
Windows broadcasts messages to running applications, giving them a chance to save data and settings. Applications can also request a little extra time to finish what they’re doing.
Windows closes the user sessions for each logged on user.
Windows sends messages to services notifying them that a shutdown has begun, and subsequently shuts them down. It shuts down ordered services that have a dependency serially, and the rest in parallel. If a service doesn’t respond, it is shut down forcefully.
Windows broadcasts messages to devices, signaling them to shut down.
Windows closes the system session (also known as “session 0”).
Windows flushes any pending data to the system drive to ensure it is saved completely.
Windows sends a signal via the ACPI interface to the system to power down the PC.
And boot:
After pressing the power button, the PC’s firmware initiates a Power-On Self Test (POST) and loads firmware settings. This pre-boot process ends when a valid system disk is detected.
irmware reads the master boot record (MBR), and then starts Bootmgr.exe. Bootmgr.exe finds and starts the Windows loader (Winload.exe) on the Windows boot partition.
Essential drivers required to start the Windows kernel are loaded and the kernel starts to run, loading into memory the system registry hive and additional drivers that are marked as BOOT_START.
The kernel passes control to the session manager process (Smss.exe) which initializes the system session, and loads and starts the devices and drivers that are not marked BOOT_START.
Winlogon.exe starts, the user logon screen appears, the service control manager starts services, and any Group Policy scripts are run. When the user logs in, Windows creates a session for that user.
Explorer.exe starts, the system creates the desktop window manager (DWM) process, which initializes the desktop and displays it.
The thing to remember is that in a traditional shutdown, the user sessions are closed and in the kernel session services and devices are closed to prepare for shutdown. In Windows 8, they close the user session but instead of closing the kernel session, it is hibernated. Hibernation basically means saving the system state and memory on disk (hiberfil.sys), and then reading that back on resume. Pairing it with boot gives a boost for boot times, since reading the hiberfile and reinitializing drivers is faster on most systems they’ve tested. Here are some helpful graphs for those of you skimming past the words:
