Vista starter edition limitations

With the exception of Windows Vista Starter, all editions support both bit x86 and bit x64 processor architectures. On 5 September , Microsoft announced USD pricing for the four editions available through retail-channels.

It has made available new license and upgrade-license SKUs for each edition. Microsoft characterizes the packaging for the retail-editions of Windows Vista as "designed to be user-friendly, [ The Windows Vista disc itself uses a holographic design similar to the discs that Microsoft has produced since Windows Windows Vista Starter Edition desktop, as denoted by the watermark on the bottom right corner.

These editions can run bit programs by running them within the WOW64 subsystem. Most bit programs can run natively, though applications that rely on device drivers will not run unless those device drivers have been written for bit Windows. Most older hardware doesn't have the necessary support to get the drivers written.

Other applications may have difficulty as well. For example, the Visual Basic 6 IDE will run natively on bit editions, but will not run at all on bit editions. Adobe Premier Elements is bit and the full Adobe Premier is available for bit Vista - with more capability but at a much higher price.

Various reviewers have reported that the bit editions of Windows Vista outperform their bit counterparts in synthetic benchmarks such as PassMark. Those who work with extremely large files may realize noticeably greater gains in performance, in some cases as dramatic as ten times the previous speed. This is because bit applications can address larger amounts of memory and thus result in less file swapping — one of the biggest factors that can affect data processing speed.

All bit versions of Microsoft operating systems currently impose a 16 TB limit on address space. Processes created on the bit editions of Windows Vista can have 8 TB in virtual memory for user processes and 8 TB for kernel processes to create a virtual memory of 16 TB. The Commission concluded that Microsoft "broke European Union competition law by leveraging its near monopoly in the market for PC operating systems onto the markets for work group server operating systems and for media players".

After unsuccessful appeals in and , Microsoft reached an agreement with the Commission where it would release a court-compliant version, Windows XP Edition N , that does not include the company's Windows Media Player but instead encourages users to pick and download their own media player. Like the European Commission decision, this decision was based on the grounds that Microsoft had abused its dominant position in the market to push other products onto consumers. Unlike that decision, however, Microsoft was also forced to withdraw the non-compliant versions of Windows from the South Korean market.

As a continuance of these requirements, Microsoft released "N" and "KN" variants of some editions of Windows Vista that exclude Windows Media Player , as well as "K" and "KN" editions that include links to third-party media player and instant messaging software.

Two additional editions of Windows Vista have been released for use by developers of embedded devices. Microsoft lists the system requirements for these editions as being the same as their desktop variants.

These editions are licensed exclusively for the development of embedded devices. Upgrade paths from Windows XP and between different Vista editions.

Dotted lines indicate the need for a "clean install". However, not all potential upgrade combinations exist. The accompanying chart indicates the possible upgrade paths:. Note: If a user is running a bit version of Windows a user can only upgrade to another bit version: to upgrade from bit to bit requires a clean install.

The following table specifies the limits on physical memory for Windows Server R2. Windows Server R2 is available only in bit editions. If the memory is remapped, X64 Windows can use this memory.

Any X64 Windows or X86 Server release can. The limit that these versions impose is the highest permitted physical RAM address, not the size of the IO space. For example, drivers could map the "lost" memory regions located above 4 GB and expose this memory as a RAM disk.
