Windows 7âs evolution compared to Windows Vista is undeniable, and the lucky few that so far have had access to the RTM bits of the latest Windows client can confirm this. But fact of the matter is that even in Beta Build 7000 development stage, Windows 7 bested Vista, and the boot time performance drag race is an illustrative example in this regard. However, Windows 7 startup speeds manage to leave its precursor in the dust. Some of you might remember reading about the 11-second boot Windows 7 delivered in a demonstration courtesy of Ruston Panabaker, Microsoft’s principal program manager of strategic silicon partnering. (via PCMag and Beyond Binary)
Yes, Windows 7 booting in just 11 seconds. My first question was, what kind of computer was Panabaker running, for obvious, and geeky, reasons. So I went ahead, and shot an email to Microsoft asking for details about the hardware configuration of the 11-second Windows 7 boot machine. Here is the answer a company spokesperson provided me: âThis was ran on a Quad-core 1.7 GHz Nehalem [Core i7] processor on a Calpella chipset, 2GB of memory, 80 GB Intel X25-M SSD (1st gen). In the set up, the log-in screen was turned off in the user control panel.â
However, the Microsoft representative noted that the 11-second boot represented just the startup time for Windows 7. âNote: BIOS post is in addition to this,â the company spokesperson added. Read More»

What, exactly, are supercomputers? The clue is in the name, really: theyâre powerful computers capable of calculating many millions of floating operations per second (FLOPS) essentially, theyâre very, very fast.
While any array of powerful computers, such as a modern-day web server which consists of several motherboards (the main circuit board of a computer) running in parallel can be considered a supercomputer, generally the term is reserved for machines that dedicate their entire hardware to one complex task at any given time.
Take the NEC Earth Simulator in Japan, for example, which was created specifically for modelling weather problems associated with global warming. Or the worldâs fastest computer, BlueGene/L at Lawrence Livermore National Laboratory in the US, which simulates the behaviour of biomolecular structures and protein folding. Itâs capable of 600 trillion FLOPS (tera-FLOPS or TFLOPS), whereas, the six-year-old Earth Simulator is only capable of 36TFLOPS. BlueGene/L wonât hold the top spot for long, though. Supercomputers twice as powerful will be online soon. Read More»

Microsoft is optimizing Windows 7 in order to increase performance, and, in this context, the dispatcher lock is one of the components that has got cut off . According to the Redmond company, fewer hardware locks are synonymous with boosted parallelism, namely a new level of efficiency when it comes down to taking advantage of modern processing architectures. This is valid for Windows Server 2008 R2, namely Windows 7 Server, and, naturally, also for the Windows 7 client, since the two operating systems share the same code base.
âWith Windows 7, the dispatcher lock is replaced with several finer-grained synchronization techniques, thus effectively distributing resource contention. The main benefits for applications include increased system performance and more optimal use of available hardware resources,â Phil Pennington, Windows Server Technical Evangelism, revealed.
Evolving from Windows Vista, Windows 7 is embracing the many core CPU world, delivering the promise of enhanced performance through the advantage represented by parallel computing. However, in order for Win7 to be tailored to many core processors, the platform’s kernel had to be freed from past relics such as the dispatcher lock. Read More»

If youâre upgrading a computer running Windows XP, you can save money by opting for an upgrade rather than the full version of Windows Vista.
However, you canât necessarily perform an âin-placeâ or âover-the-topâ upgrade; sometimes you have to perform a clean installation of Windows Vista, which means backing up and reinstalling all your current programs, folders and files. The table shows where an over-the-top upgrade is possible.
In practice, a clean install means a fresh start; anything short of this can carry over problems from your old, cluttered version of Windows XP. Strictly speaking, when Windows Vista installs itself over Windows XP, it actually does perform a clean install and then imports all the old settings.
This should help prevent problems and can even, in principle, carry through hardware drivers that canât be installed under Windows Vista itself, thereby preserving the working life of older devices. However, weâd recommend a truly clean install whenever possible. Read More»

Microsoft has shared bits and pieces of how it is adding new features to its development tools to better support parallel processing.
But the next release of Windows client and server also are going to incorporate changes designed to improve their parallel-processing support.
While Microsoft execs and those whoâve managed to get their hands on early builds of Windows 7 have focused largely on user-interface tweaks in Windows 7, there will be some under-the-covers changes, too. Microsoft officials have said on the record that deep-level changes between Windows Vista and Windows 7 will be kept to a minimum, in order to insure application and driver compatibility. Yet Microsoft officials acknowledge that Win32, the core of Windows, is not suited for asynchronous, concurrent computing.
Microsoft is taking the first steps toward remedying this limitation with Windows 7 and its joined-at-the-hip sibling, Windows 7 Server (the product currently known as Windows Server 2008 R2). Read More»

If you use a 64-bit version of Windows Vista on a computer with multiple processors or on a multi-core (dual-core, quad-core) processor (which is quite usual), you can use a simple setting to accelerate booting of the computer (OS).
Depending on the configuration of your computer, this setting may result in a smaller or substantial improving of the Windows booting time. Please be aware that this setting is not intended for novice users and it can cause booting problems on incompatible (mostly “noname”) computers.
By default, Vista detects and switches to a multi-processor core only after the basic functions of Windows are loaded – for actual booting it uses only a single core (logical processor). With the following setting you will enable using of all available cores/processors also for booting.
Run the MSCONFIG command (Start > Run) and go to the “Boot” tab. There click the “Advanced options” button. In the “BOOT advance options” dialog check the “Number of processors” option and set the number of processor cores you have available in your PC. Exit the command with OK. The following restart should be faster. Read More»

Laptops are complex little machines with a variety of configuration options which can lead to very confusing buying decisions. In this article, we are going to cover out factors that one should consider before purchasing a laptop. These 6 factors are the crux of any laptop purchase and by using these as a guideline, you can land the most appropriate mobile PC for your needs.
1- Weight
The lighter the laptop, the easier it is to move around. Prices usually have an inverse relationship with the weight of a laptop. Hence the lightest of laptops will almost (always) cost more than the heaviest ones.
Another relationship is the features of a laptop which would affect the weight of the laptop, which can be if it has a powerful graphics card, or a larger screen etc. The laptop will end up being comparatively heavier and more expensive. So keep a look out for that.
2- Power Consumption
Battery life is critical for users who are on the go. On an average workload, a regular low budget laptop would easily give you 2.5 to 3 hours of battery time. A fairly good machine would easily clock in 4 hours. Read More»

The System tool in Control Panel uses currentspeed to do its reporting rather than maxspeed, but the System tool may display the wrong clock speed for the Central Processing Unit (CPU).
As of January 2002, Windows XP uses the currentspeed value rather than the maxspeed value because the maxspeed value was reporting inconsistent values.
After startup, the processor may not correctly reflect its correct speed until a program utilizes processor cycles.
The computer basic input/output system (BIOS) in some laptop computers may throttle the processor because of heat, load, power AC/DC. Read More»
