Hi
Lets us all post the usefull tips ,tricks and information for Windows Vista guys.
Please go through the difference between 32-bit and 64-bit Windows Vista.
32-Bit
A 32-bit processor can reference 2^32 bytes, or 4 GB of memory. These 32-bit processors were standard at a time when 4 GB was thought to be more than enough memory space for software applications on Windows. When a process, such as running a program, is created on an x86 Windows computer with a 32-bit processor, the operating system allocates its 4 GB of virtual memory, irrespective of the actual physical memory installed on a system. Half of that allocated memory is user-accessible memory, while the other half is for kernel processes such as drivers. Modern computing systems increasingly confront the 4 GB ceiling thanks to memory-intensive applications and the need to store multiple processes in memory simultaneously.
64-Bit
The 64-bit processors are theoretically capable of referencing 2^64 locations in memory, or 16 exabytes, which is more than 4 billion times the number of memory locations 32-bit processors can reference. However, all 64-bit versions of Microsoft operating systems currently impose a 16 TB limit on address space and allow no more than 128 GB of physical memory due to the impracticality of having 16 TB of RAM. Processes created on Windows Vista x64 Edition are allotted 8 TB in virtual memory for user processes and 8 TB for kernel processes to create a virtual memory of 16 TB.
To summarize, the ability of Windows Vista x64 Edition to add address more memory space than previous versions of Windows helps minimize the time spent swapping processes in and out of memory by storing more of them in RAM.
Misconceptions about Windows Vista x64 Edition
Operating systems such as Windows Vista x64 Edition are not automatically faster than their 32-bit counterparts. In some cases, they may even perform slower because of the larger pointers as well unrelated OS overhead. Overall, an application’s performance depends on what it is used for and how it is implemented. Emulated applications running within the Windows on Windows 64 layer (discussed in more detail later in this article) will not be able to address any more memory than they could on a 32-bit system.
Drivers supported by Windows Vista x64 Edition will not necessarily be supported by the 64-bit edition of Windows XP. National Instruments will support Windows Vista x64 Edition with driver releases and software updates, but there are no plans for NI to support Windows XP x64 Edition.
Hardware Requirements for the Different Versions of Windows Vista
Windows Vista requires significantly more processing power than previous versions of Microsoft Windows. The enhanced Windows user interface promises to be one of the biggest consumer attractions to the new operating system, but it places considerably greater demands on a system’s processor, graphics card, and memory. Both editions of Windows Vista share these performance requirements and offer compatible modes for use on slower systems; however, to install Windows Vista x64 Edition, you must have a 64-bit processor. Conversely, the x86 edition of Windows Vista can run on a 64-bit processor as a 32-bit operating system.
Some motherboards that work with 64-bit processors retain the limitations of 32-bit systems, so to exploit the advantages offered by the newer architecture, it is important to ensure the motherboard has a wide enough address bus. Motherboards with wider address and data buses currently still impose artificial limitations on the amount of memory due to the impracticality otherwise. Windows Vista x64 Edition allows up to 128 GB of memory – far more than most current motherboards permit - but you should consider the expandability of applications built using the new architecture as the technology improves.
Potential Benefits of Windows Vista x64 Edition
The transition to the 64-bit architecture is overwhelmingly driven by the limitations of the x86 architecture in terms of addressing memory. Applications running on Windows Vista x64 Edition should theoretically experience improved performance because of the larger quantity of available memory, even if the application is running within the WoW64 layer. Much like the advantage offered by increasing physical memory in a 32-bit system, the larger memory space on Windows Vista x64 Edition allows more processes to actively reside in the system RAM simultaneously.
This change potentially eliminates or reduces time spent loading and switching between processes, a condition that can lead to “thrashing†when all the processor’s efforts are spent merely loading and switching between threads. To reap the benefits of a 64-bit operating system such as Windows Vista x64 Edition, you should invest in a large amount of RAM (4 GB or more) and a compatible motherboard.
For Windows Vista x64 Edition, Microsoft also requires a digital signature on all drivers. By requiring new, signed drivers, Microsoft aims to reduce failures and improve stability by shining a spotlight on vendor responsibility for bugs. With Windows Vista x86, administrators can install unsigned drivers, but Microsoft continues to discourage their use. All nonlegacy National Instruments drivers will be digitally signed and available for both the 32-bit and 64-bit editions of Windows Vista after Microsoft releases the OS.
Potential Drawbacks to Windows Vista x64 Edition
Windows XP was available only as a 32-bit operating system for 32-bit processors until 2005, when Microsoft released a 64-bit edition. This version of Windows XP did not see widespread adoption due to a lack of available software and hardware drivers. Vendors were hesitant to invest in a platform that seemed more novel than practical for consumers at the time, which led to compatibility issues with common devices such as sound and graphics cards.
Given the increasing number of 64-bit processors, Windows Vista x64 Edition is unlikely to suffer the same lack of support. However, it will take some time for vendors to release 64-bit software and hardware drivers. A potential drawback stems from the possibility that some hardware vendors may not release Windows Vista x64 Edition-compatible versions of drivers quickly, or they may not offer signed drivers, which Windows Vista x64 Edition requires.
Many 32-bit applications will not be updated for Windows Vista x64 Edition; however, most 32-bit software will still function because of a Microsoft emulation layer. This emulation layer, known as Windows on Windows 64 or WoW64, enables 32-bit programs to run as though on a 32-bit version of Windows by translating instructions passing in and out of 32-bit applications into 64-bit instructions. Emulated programs act as though they are running on an x86 computer and operate within the 2 GB of virtual memory that a 32-bit version of Windows allocates to every process. However, despite Wow64, 32-bit programs on Windows Vista x64 Edition cannot take advantage of the larger 64-bit address spaces or wider 64-bit registers on 64-bit processors.
To work with Windows Vista x64 Edition, you must invest in large quantities of RAM. The overhead associated with Windows Vista is larger than that of prior operating systems such as Windows XP, so slower systems are likely to see performance decreases.
Evaluating an Engineering System on Windows Vista
Windows Vista represents an upgrade from Windows XP for consumer PC users in many ways, and the 64-bit edition in particular is drawing significant attention. The 64-bit processors have enormous potential that modern PCs are not fully exploiting, which means there is significant room for growth during the next few years. However, Windows Vista x64 Edition was not designed explicitly for scientists and engineers, and not all scientific and engineering applications will immediately benefit from migrating to a Windows Vista x64 Edition PC.
The following types of applications could see performance benefits on Windows Vista x64 Edition, provided that both 64-bit application software and drivers are available:
Applications for creating digital content in computer-aided design and digital video editing
Applications that require mathematical precision and floating-point performance
Applications that involve large, high-performance databases
Vision acquisition and analysis applications with large amounts of data moving directly into memory at rapid rates
If your application does not fall into one of these categories, you should carefully consider the necessity of using Windows Vista x64 Edition. Not every application stands to benefit from the x64 architecture, and it will take time for Windows Vista x64 Edition to gain widespread adoption.
Summary
Windows Vista x64 Edition represents the first mainstream 64-bit operating system from Microsoft in terms of general availability and support from third-party add-on vendors. Because of this, moving from a 32-bit operating system such as Windows XP to a 64-bit operating system such as Windows Vista x64 Edition merits serious consideration in many cases.
However, the feasibility of successfully making the jump to Windows Vista x64 Edition depends largely on your application and its requirements. For some, Windows Vista x64 Edition offers much needed performance improvement, while for others, it could needlessly complicate applications designed to operate on x86 platforms or even have a negative effect on performance.
