There are many myths for the poor performance of the windows vista commercially
Firstly i would like to claim that windows vista does not offer much more than windows xp
this is is a sign of sheer ignorance and here u have to read ignorance as euphemism.
secondly the matter of fact is that Windows Vista's sales are suffering because Vista has been launched on a market saturated by Windows XP. And it needs to erode XP's dominance on the operating system's market in order to increase its own market share. Just look at the statistics... Windows XP has begun losing its grip on the market concomitantly with the release of Vista. Another downside of Windows Vista is the fact that the operating system implies some adjacent hardware costs, as it requires additional resources. And last but not least, Microsoft has to fight the customer perception that Windows XP is good enough. XP is five years old. While not being completely expired, XP and even SP2, you must keep in mind that they were developed in a totally different world than the one in which we live today. In conclusion... don't blame it on the moonlight, don't blame it on the sunshine...
The third reason is that windows vista is not as secure as declared by the microsoft
it is defective from the core itself In windows vista or in any operating system for that matter
kernel is the most important part of security and heart of the computer
according to the microsoft
windows vista has 3 new technologies designed to bulletproof the kernel.
1.Driver signing
2. code integrity
3. PatchGuard are the pillars of the 64-bit editions of Windows Vista's kernel.
coming to kernel patch
Kernel Patch Protection allows us to provide increased reliability, consistent performance, and additional levels of security for 64-bit Windows by preventing unauthorized software from modifying or patching the Windows kernel using unsupported methods while it’s running.
Kernel Patch Protection works by providing extensibility that allows potential extensions to be planned for, reviewed and tested thoroughly during product development.Instead of allowing multiple parties to directly modify kernel instructions and data structures in undocumented and unsupported ways, providing supported mechanisms and APIs will strengthen the security, performance and reliability of Windows Vista,” revealed Microsoft’s Stephen Toulouse, senior program manager for the Trustworthy Computing Group.
Symantec has long contested the legitimacy and validity of the Kernel Patch Protection, but Microsoft failed to budge from its position. Via driver signing, Microsoft controls all the drivers loaded into the kernel. And code integrity safeguards the core operating system and ensures that it has not been tampered with in any way.
“Symantec researchers investigated the feasibility of disabling all three key kernel integrity technologies: driver signing, Code Integrity, and PatchGuard. Results have shown that all three technologies can be permanently disabled and removed from Windows Vista after approximately one man-week of effort. A potential victim need make only one mistake to become infected by a threat that does the same. The result: All new security technologies are stripped from Windows Vista in their entirety,” concluded Symantec.
