This is an excerpt from my ActiveWin Vista review:
Some of the more technical features of Vista are what I would consider to be
ready for the mainstream. For instance, all Editions of the OS except for
Starter Edition will be available in 64-bit flavors'. The interface and
features are identical in every way to its x86 counterpart except for
compatibility with 32 bit device drivers and 16 bit applications. The
advantages of a 64 bit Windows for consumers is not immediately seen, but
power hungry users such as scientist, number crunching business intelligence
users and environments where video editing/rendering and DNA Modeling are
done will see the deep benefits of being able to handle up to 128 GBs of
RAM, although there aren't any Workstation's that can hold that amount of
memory, its comforting knowing the capability is there I guess. Driver
support is still an issue for 64-bit Windows, but with the aim of making
64-bit computing mainstream through Windows Vista, developers will support
the platform more readily I believe. I personally have not had any driver
issues with Vista x64 except for the thumb drive hanging the system when
plugged into a particular USB port, everything else works just fine.
All built in Windows applications are 64-bit native such as Windows Movie
Maker and Photo Gallery although there remains a 32-bit Internet Explorer to
maintain compatibility with web extensions that might not have been updated.
Performance is still an issue, and even on the RTM release I truly have to
say I am not satisfied. From installation to general use, the 64-Bit version
of Vista feels groggy, running applications such as Office 2007 take a hit,
applications take much longer to launch and at times become non-responsive.
Hardware is also another factor when it comes to performance and 64-bit
Windows, and I honestly believe to get a satisfactory experience, a dual
core processor with at least 2 GBs of RAM and a 256 MB video card or higher
is a recommended minimum. Microsoft has announced all kernel mode drivers
must be signed before they can be installed. This will ultimately be a
benefit for the consumer to provide a more reliable experience, the
essential aim, which is to reduce system failure as a result of badly
written device drivers or drivers written with the intent of causing
malicious harm, you can't go wrong there.
Another security feature that has been causing a lot of controversy called
Patch Guard provides a protective shield around the Windows Kernel that
prevents certain individuals from simply patching it, whether it's to
optimize third party applications or for unknown malicious purposes. Kernel
patching was not something consented by Microsoft in the first place, in
which case, they saw the 64-bit release of Vista as an opportunity to start
a clean slate and educate both developers and users about the negatives of
doing this in the first place. But this has affected certain Security
vendors such as MacAfee (which is still unsatisfied) and Symantec, which
have since worked out an agreement with Microsoft to get controlled access
to the Windows Kernel. Unlike Windows Vista x64, Vista x86's kernel remains
patchable. So for persons who want a really, really, secure and powerful
version of Windows, Vista definitely has something to offer.
