Wij stellen vandaag de versie RC van SP1 van het Uitzicht van Vensters ter beschikking, vonden hier op MSDN en hier op TechNet, met een FAQ hier. Ik nodig u uit om SP1 RC te downloaden te installeren en te gebruiken en ons te laten van uw ervaring op de hoogte zijn door te verstrekken uw terugkoppel hier.

Alvorens u SP1 RC installeert, te houden gelieve de volgende gedetailleerde punten van raad in gedachten, in dit korte artikel:

• Als u een vroegere versie van SP1 Bèta geïnstalleerdu hebt, moet u het voorafgaand aan het installeren van RC desinstalleren.
• Dit is pre-versiecode en zal vóór de definitieve versie veranderen.
• Deze pre-versiesoftware wordt verstrekt voor testende slechts doeleinden. Microsoft adviseert niet installerend deze software op primaire of opdracht-kritieke systemen.
• Microsoft adviseert dat u steun uw gegevens voorafgaand aan het installeren van om het even welke pre-versiesoftware.
• SP1 van het Uitzicht van vensters de Kandidaat van de Versie is tijd-beperkte software. Het zal niet meer na 30 Juni, 2008 werken en zou voorafgaand aan die datum moeten worden gedesinstalleerd.
• De steun is door zelfhulp en peer steun via SP1 van het Uitzicht van vensters forum. De bijgestane steun (telefoon, e-mail en online praatje) is niet beschikbaar bij de Steun van Microsoft voor deze versie RC van SP1. De steun is niet beschikbaar via dit blog.
• Als u Pak 1 van de Dienst de Kandidaat van de Versie installeert, adviseert men sterk dat u ook van plan bent om de definitieve versie van SP1 van het Uitzicht van Vensters te installeren wanneer het in de eerste wordt vrijgegeven

Zeker is het geen nieuws aan u dat wij de Update van Vensters gebruiken om aan de gang zijnde verbeteringen aan onze klanten voortdurend te leveren zodat de Vensters altijd bijgewerkt is. Plus, elimineert het doen dit de behoefte om op grotere versies zoals de dienstpakken te wachten. Sommige updates worden vrijgegeven aan de gemeenschap want algemeen voorafgaand aan levering via de Update van Vensters terugkoppel, zoals is vandaag het geval. Het team van het Nut van Vensters ontwikkelt vandaag een andere update op Het Centrum van de Download van Microsoft . The update is categorized as a "preview release" and may be subject to change before it is released via Windows Update (we expect that to occur in January).

Today's update preview release is geared toward improving reliability and performance in Windows Vista and we highly encourage you to install it. It includes:

• Improvement of previous issues affecting going into or resuming from sleep/hibernate under some scenarios
• Update to address a previous issue with the disk spindown feature to improve battery life for portable systems
• Up to 15% improved performance of disk I/O (i.e., copying/moving/deleting large files)

I'm running this update on one of my systems -- the one I'm using to draft this post, in fact. I suggest you try it out and let us know how you fare. You can find more information about today's update preview release in this KB article.

Today Nick announced the availability of the release candidate for Windows Vista SP1. I had a chance to get the RC build of Windows Vista SP1 installed a few days ago. I decided to roll the RC out on all of my PCs which showcase a variety of device types and scenarios:

• My Main Desktop PC running Windows Vista Ultimate x64 - check.
• My Test/Work PC running Windows Vista Business - check.
• My Dell Vostro 1500 Laptop running Windows Vista Ultimate - check.
• My Samsung Q1 UMPC running Windows Vista Home Premium - check.
• My Digital CableCard PC running Windows Vista Home Premium - check.

In installing the RC on my PCs, I did a combination of using the standalone installer and Windows Update. Before proceeding to install the SP1 RC bits, I first needed to uninstall the SP1 beta bits first. Users looking to install the Windows Vista SP1 RC will need to uninstall any previous version of SP1 prior to the installation of the RC from either Windows Update or the standalone installer. With Windows Update, once SP1 was downloaded, a new series of screens telling me about SP1 appeared. The same series of dialog screens seen in the standalone installer is now launched when installing Windows Vista SP1 via Windows Update. This will be really helpful to the user in installing Windows Vista SP1. Previously with the beta, there was no guidance from Windows Update in installing Windows Vista SP1 like there was with the

Today we're making available the release candidate (RC) of Windows Vista SP1 via Microsoft Connect, and tomorrow subscribers to TechNet and MDSN will have access to those RC bits too. In addition, the RC will be available to the public next week via Microsoft's Download Center. The release candidate phase of beta software is typically the final phase before the RTM (release-to-manufacturing) of a product and indicates that the code has attained a significant level of performance and stability.

Let me call out several changes made since the Beta release of Service Pack 1 -- many of which came about as a result of direct feedback from our Beta-testing community (thank you!):

• The size of the standalone installers have decreased significantly. For example, the standalone installer packages consisting of all 36 languages (x86 and x64 chip architectures) are smaller by over 50%. The standalone installer packages consisting of just the 5 languages (again, x86 and x64) slated for initial release are more than 30% smaller in size.
• The required amount of disc space for SP1 installation has also decreased significantly. Furthermore, with the RC, if more space is required to install SP1, an error message will now display exactly how much space is needed to complete the installation.
• Previous SP1 versions left behind a directory of files that wasn't needed after installation and occupied about 1GB of space; the RC includes automatic disk clean-up to remove this directory.
• Installation reliability has been improved based on bug reports and error codes reported from Windows Update (thanks, Beta

This weekend I completed the roll-out of my new HP MediaSmart Server running Windows Home Server. I ordered the HP MediaSmart Server EX470. I originally had Windows Home Server running on my Dell Dimension E520 but decommissioned it when I created my "Ultimate" PC. I really wanted to try out the experience the average consumer will have in purchasing a Windows Home Server and setting it up in their home. The HP MediaSmart Server seemed like the perfect choice in checking out the Windows Home Server experience.

The HP MediaSmart Server EX470 has the following specs:

• Processor - AMD 1.8GHz 64-bit Sempron
• Memory - 512MB DDR
• Interfaces - 4 USB 2.0 Ports, 1 eSATA Port
• Storage - 1 500GB SATA 7200 RPM

Measuring the performance of an operating system is a tricky thing. At the same time, it's the right and necessary thing to do, because performance is one of many criteria important to customers. Part of the trick of measuring performance is to time testing execution with the product cycle such that the results are as meaningful as possible for customers; this helps them make a better decision by making use of the full array of available information. As one example, about a year ago we commissioned a firm called Principled Technologies to conduct a study comparing Windows XP SP2 to Windows Vista RTM. That study found the performance measures of the two operating systems were within the same range for many tasks that home and business users frequently perform under real-world conditions.

My point is that we waited to conduct these benchmarking tests until Windows Vista had reached the RTM milestone in the product cycle, as this allowed us to provide our customers the most meaningful data available at the time -- the data most likely to directly affect their decision to upgrade to Windows Vista. We do a whole range of performance tests at every stage of the OS development process, but, as a general rule, we avoid sharing benchmark tests of software that hasn't gone RTM (i.e., final code). This explains why we have not to date published any findings of benchmark tests (nor commissioned anyone to do so) on
