However, because nearly all users are administrators by default in previous versions of Windows, many developers have incorrectly assumed that their applications will always execute with these privileges, or have not regression tested their code for LUA bugs. Microsoft added file and registry virtualization technology as well as application compatibility shims to reduce the number of these legacy

Password Restore

A password cannot be restored on Windows Vista Starter and Windows Vista Home Basic. This means that if an administrator forgets his/her password on any of these Operating Systems, they will not be able to download items or make major changes to the computer on a limited user account. However, a password can be restored on Windows Vista Home Premium, Windows Vista Business, Windows Vista Ultimate, and on Windows Vista Enterprise using a floppy disc or a USB flash drive. Passwords are restored by inputting the wrong password during log-in, then clicking "Reset Password".

" with which to sign the driver.

The following criticisms/claims have been made regarding this requirement:
  • that it reduces Vista's compatibility with older hardware
  • that it disallows experimentation from the hobbyist community. The required authenticode certificates for signing Vista drivers are expensive and out of reach for small developers, usually about $400–500/year (from VeriSign

Unsigned drivers could initially be installed through the use of tools included with Vista, as well as some third party utilities such as Atsiv. However Microsoft has closed these workarounds with hotfix KB932596, which is included in Service Pack 1. Microsoft claims that using strict driver handling means more security, while critics note that few if any security attacks have manifest in software drivers, which are almost always written by equipment manufacturers.

Flaws in memory protection features

Security researchers Alexander Sotirov

 (ASLR). The result of this is that any already existing buffer overflow bugs that, in Vista, were previously not exploitable due to such features, may now be exploitable. This is not in itself a vulnerability: as Sotirov notes, "What we presented is weaknesses in the protection mechanism. It still requires the system under attack to have a vulnerability. Without the presence of a vulnerability these techniques don’t really [accomplish] anything." The vulnerability Sotirov and Dowd used in their paper as an example was the 2007 animated cursor bug, CVE

-2007-0038.

One security researcher (Dino Dai Zovi) claimed that this means that it is "completely game over" for Vista security. though Sotirov refuted this, saying that "The articles that describe Vista security as 'broken' or 'done for,' with 'unfixable vulnerabilities' are completely inaccurate. One of the suggestions I saw in many of the discussions was that people should just use Windows XP. In fact, in XP a lot of those protections we’re bypassing [such as ASLR] don’t even exist."

Digital rights management

Another common criticism concerns the integration of new forms of digital rights management

 and Blu-ray discs, but it will not be enabled until at least 2010.

The Protected Video Path mandates that encryption must be used whenever content marked as "protected" will travel over a link where it might be intercepted. This is called a User-Accessible Bus (UAB). Additionally, all devices that come into contact with premium content (such as graphics cards) have to be certified by Microsoft. Before playback starts, all the devices involved are checked using a Hardware Functionality Scan (HFS) to verify if they are genuine and have not been tampered with. Devices are required to switch off or artificially degrade the quality of any signal outputs that are not protected by HDCP. Additionally, Microsoft maintains a global revocation list for devices that have been compromised. This list is distributed to PCs over the Internet using normal update mechanisms. The only effect on a revoked driver's functionality is that high-level protected content will not play; all other functionality, including low-definition playback, is retained.

  • Some newer high-definition monitors are not HDCP-enabled, even though the manufacturer may claim otherwise.
  • The added complexity makes systems less reliable.
  • Since non-protected media are not subject to the new restrictions, users may be encouraged to remove the protection in order to view them without restrictions, thus defeating the content protection scheme's initial purpose.
  • Protection mechanisms, such as disabling or degrading outputs, may be triggered erroneously or maliciously, motivating denial-of-service attacks.
  • Revoking the driver of a device that is in wide use is such a drastic measure that Gutmann doubts Microsoft will ever actually do so. On the other hand, they may be forced to because of their legal obligations to the movie studios.

Reaction to criticism

Ed Bott, author of Windows Vista Inside Out, has published a three-part blog which rebuts many of Gutmann's claims.

Ed Bott's criticisms can be summarized as follows:
  • Gutmann allegedly based his paper on outdated documentation from Microsoft and second-hand web sources.
  • Gutmann allegedly quotes selectively from the Microsoft specifications.
  • Gutmann allegedly did no experimental work with Vista to prove his theories. Rather, he makes mistaken assumptions and then speculates wildly on their implications.
  • Gutmann's paper, while presented as serious research, is really just an opinion piece.


Technology writer George Ou claims that Gutmann's paper relies on unreliable sources and that Gutmann has never used Windows Vista to test his theories.

Gutmann has responded to both Bott and Ou in a further article., which states that the central thesis of Gutmann's article has not been refuted and the response of Bott is "disinformation".

Microsoft has published a blog entry with "Twenty Questions (and Answers)" on Windows Vista Content Protection, intending to refute some of Gutmann's arguments.

  • Microsoft is not to blame for these measures. The company has been forced to do this by the movie studios.
  • The Protected Video Path will not be used for quite a while. There is said to be an agreement between Microsoft and Sony that Blu-ray discs will not mandate protection until at least 2010, possibly even 2012.
  • Vista does not degrade or refuse to play any existing media, CDs or DVDs. The protected data paths are only activated if protected content requires it.

Hardware requirements and performance

According to Microsoft, "nearly all PCs on the market today will run Windows Vista" and most PCs sold after 2005 are capable of running Vista.

Much hardware that worked in XP does not work, or works poorly in Vista, due to companies going out of business, lack of interest in supporting old hardware, and changes in driver models. Service Pack 1 for Vista is said to fix many of these problems.

Speed

Tom's Hardware published benchmarks in January 2007 that showed that Windows Vista executed typical applications more slowly than Windows XP with the same hardware configuration. A subset of the benchmarks used were provided by Standard Performance Evaluation Corporation
Standard Performance Evaluation Corporation
The Standard Performance Evaluation Corporation is a non-profit organization that aims to "produce, establish, maintain and endorse a standardized set" of performance benchmarks for computers....

 (or SPEC), who later stated that such "results should not be compared to those generated while running Windows XP, even if testing is done with the same hardware configuration." SPEC acknowledges that an apple-to-apples comparison cannot be made in cases such as the one done by Tom's Hardware, calling such studies "invalid comparisons." However, the TomsHardware report conceded that the SPECviewperf tests "suffered heavily from the lack of support for the OpenGL graphics library under Windows Vista". For this reason the report recommended against replacing Windows XP with Vista until manufacturers made these drivers available.

The report also concluded in tests involving real world applications Vista performed considerably slower, noting "We are disappointed that CPU-intensive applications such as video transcoding with XviD (DVD to XviD MPEG4) or the MainConcept H.264 Encoder performed 18% to nearly 24% slower in our standard benchmark scenarios". Other commonly used applications, including Photoshop and WinRAR, also performed worse under Vista.

Many low-to-middle-end machines that come with Windows Vista pre-installed suffer from exceptionally slow performance with the default Vista settings that come pre-loaded, and laptop manufacturers have offered to 'downgrade' laptops to Windows XP—for a price. However, this "price" is unnecessary, as Microsoft allows users of Windows Vista and Windows 7 to freely "downgrade" their software by installing XP and then phoning a Microsoft representative for a new product key. http://www.eweek.com/c/a/Windows/Microsoft-Windows-XP-Users-Can-Keep-Downgrade-Rights-491684/

File operation performance

When first released in November 2006, Vista performed file operations such as copying and deletion more slowly than other operating systems. Large copies required when migrating from one computer to another seemed difficult or impossible without workarounds such as using the command line. This inability to efficiently perform basic file operations attracted strong criticism. After six months, Microsoft confirmed the existence of these problems by releasing a special performance and reliability update, which was later disseminated through Windows Update, and is included in Service Pack 1.

Nonetheless, one benchmark reported to show that, while improving performance compared to Vista's original release, Service Pack 1 does not increase the level of performance to that of Windows XP. However, that benchmark has been questioned by others within ZDNet. Ed Bott both questions his colleagues' methods and provides benchmarks that refute the results.

Game performance

Early in Vista's lifecycle, many games showed a drop in frame rate compared to that experienced in Windows XP. These results were largely the consequence of Vista's immature graphics processing unit

s drivers, and higher system requirements for Vista itself.
Some recent benchmarks seem to suggest that, as of mid-2008, Vista SP1 is now on par with Windows XP in terms of game performance. However, game developers' recommended memory requirements on Vista are still higher (usually double) than on XP.

Software bloat

Concerns have been expressed that Windows Vista may contain

"With the release of a new operating system and its new features and higher requirements, higher power consumption is normal", as Richard Shim, an analyst with IDC noted, "when Windows XP came out, that was true, and when Windows 2000 came out, that was true."

Software compatibility

Significant problems have surfaced with other software running under Vista. According to Gartner, "Vista has been dogged by fears, in some cases proven, that many existing applications have to be re-written to operate on the new system."
Cisco has been reported as saying, "Vista will solve a lot of problems, but for every action, there's a reaction, and unforeseen side-effects and mutations. Networks can become more brittle." According to PC World, "Software compatibility issues, bug worries keep businesses from moving to Microsoft's new OS."

Microsoft has published a list of legacy applications that meet their "Works with Windows Vista" software standards as well as a list of applications that meet their more stringent "Certified for Windows Vista" standards. However, as of July 2007, software compatibility problems were still hindering adoption of Vista.

Pricing

Microsoft's international pricing of Vista has been criticized by many as too expensive. The differences in pricing from one country to another vary significantly, especially considering that copies of Vista can be ordered and shipped worldwide from the United States; this could save between $42 (€26) and $314 (€200). In many cases, the difference in price is significantly greater than was the case for Windows XP. In Malaysia, the pricing for Vista is at around RM799 ($244/€155).
At the current exchange rate, United Kingdom consumers could be paying almost double their United States counterparts for the same software.
Since the release of Windows Vista in January 2007 Microsoft has reduced the retail, and upgrade price point of Vista. Originally Vista Ultimate was priced at $399. and Home Premium Vista at $239. These prices have since been reduced to $319 and $199 respectively.

Software Protection Platform

Vista includes an enhanced set of anti-copying technologies, based on Windows XP's Windows Genuine Advantage
Windows Genuine Advantage
Windows Genuine Advantage is an anti-piracy system created by Microsoft that enforces online validation of the licensing of several recent Microsoft Windows operating systems when accessing several services, such as Windows Update, and downloading Windows components from the Microsoft Download...

, called Software Protection Platform (SPP). In the initial release of Windows Vista (without Service Pack 1), a major component of this was a reduced-functionality mode, which is entered when it is detected that the user has "failed product activation" or that their copy is "identified as counterfeit or non-genuine." The technology was described in a Microsoft white paper as follows:
This was criticised for being overly draconian, especially given an imperfect false-positive record on behalf of SPP's predecessor, and at least one temporary validation server outage which reportedly flagged many legitimate copies of Vista and XP as "Non-Genuine" when Windows Update would "check in" and fail the "validation" challenge.

SPP was significantly altered in Windows Vista Service Pack 1. Instead of the reduced functionality mode, an installation of Vista left unactivated for 30 days presents the user with a nag screen prompting them to activate the operating system when they log in, changes the desktop to a solid black colour every hour, and periodically warns the user about software counterfeiting with notification balloons. In addition, updates classified as optional are not available to unactivated copies of Vista. Microsoft maintains a technical bulletin providing further details on product activation for Vista.

Windows Ultimate Extras are optional features offered to users of Windows Vista Ultimate Edition. They are accessible with Windows Update. Ultimate Extras replace the market role of Microsoft Plus!, a product sold for prior consumer releases of Microsoft Windows...

. These extras have been released much more slowly than expected, with only four available as of August 2009, almost three years after Vista was released, which has angered some users who paid extra mainly for the promised add-ons.
Barry Goffe, Director of Windows Vista Ultimate for Microsoft states that they were unexpectedly delayed on releasing several of the extras, but that "Microsoft plans to ship a collection of additional Windows Ultimate Extras that it is confident will delight its passionate Windows Vista Ultimate customers."
