My good buds on the Windows Search Team have asked me to relay some exciting new information regarding Windows Search 4.0:

Since Windows Search 4.0 (WS4.0) was released to the web on June 3rd, we've seen a good number of downloads, and a number of positive responses from customers who started using it.  Users are telling us that they're seeing better performance and reliability of search after WS4.0 is installed.  As a result, we feel it's time to make WS4.0 available to the broader audience.

In late July WS4.0 will become available for installation off Windows Update. Customers using Windows XP will see WS4.0 available as an Optional update, meaning they can manually install it from update.microsoft.com.  Windows Vista customers will see the update as a recommended update. Depending on the Windows Update settings on your Windows Vista SP1 client, WS4.0 may be installed automatically, updating the search capability in Windows Vista SP1. 

Not everyone will get it on the same day; the release of Windows Search 4.0 will be very gradual.  While every user will be able to install the update off the Windows Update site interactively, the automatic update may not come

We're excited about the progress we've made with Windows Vista Service Pack 1.  On March 18th, Windows Vista SP1 was made available for customers who chose to manually download and install it from the Microsoft Download Center or Windows Update in English, French, German, Spanish, and Japanese.  Last week, we made the remaining languages available - giving WU users the ability to download and install Windows Vista Service Pack in any of 36 supported languages.  Today, we're happy to announce that we are beginning automatic distribution of SP1 in English, French, German, Spanish, and Japanese. 

So what does this mean? Over the next few months Microsoft will automatically distribute Windows Vista SP1 to PCs that have automatic updates turned on (Learn how to turn on automatic updating) and running English, French, German, Spanish, or Japanese via Windows Update. Automatic distribution will only occur, according to user settings, on PCs ready for SP1. After Windows Vista SP1 downloads, WU will let you know that "new updates are available." You'll then be asked to make a few clicks before the installation of SP1 will begin. 

While we're beginning automatic distribution today, you might not see it right away since

It has been almost a month since we released Windows Vista SP1 to Windows Update in 5 languages. To date: millions of people have successfully installed Windows Vista SP1 on their PCs. So we're happy to announce the next step for Windows Vista SP1 availability.

We are excited to report that today we are making Windows Vista SP1 available to folks running Windows Vista in any of the supported languages. Starting today, users will be able to choose to manually install Windows Vista SP1 via Windows Update or download the standalone installer from the Microsoft Download Center (x86 and x64) for any of the 36 supported languages, not just English, Spanish, German, French, and Japanese. For now, it is available for users who visit Windows Update or the Microsoft Download Center. We encourage most users to get Windows Vista SP1 via Windows Update-which will provide the best update experience.

Now, Windows Vista PCs of any supported language can update to SP1.  You may be aware we also make DVD images of Windows Vista with SP1 available to certain groups like TechNet Plus subscribers, MSDN subscribers, and Volume License (VL) customers. TechNet Plus and MSDN subscribers can download these DVD

I have a quick update for you about Windows Vista SP1. The Microsoft Update Blog contains some important information about updates to the SP1 prerequisite distribution plan. Starting tomorrow, we are resuming the automatic update and installation of the Servicing Stack Update.

In mid-April, we will begin distributing SP1 (in the first 5 languages) using the Automatic Update system.  We have a lot of Windows users, so not everyone will get it on the same day.  In fact, it will go to a small percentage of Windows Vista users each day. The exact timing of when you will receive it depends on when your PC is ready for Windows Vista SP1.

In addition to starting the automatic delivery of the first 5 languages, I wanted to take this opportunity to tell you that also we're on track for the initial release of SP1 in the remaining languages in mid-April.

Today, you can now download Windows Vista SP1 via Windows Update.  For those of you eager to receive the benefits of Windows Vista SP1, you can now do so.  We've seen quite a bit of questions in our comments so we want to communicate as much as possible surrounding Windows Vista SP1 and today's release to Windows Update as we can.

For those of you happy to wait, sit tight because SP1 will start downloading to PCs automatically beginning in mid-April (remember, this happens only if you have your Windows Update configured to automatically download updates and SP1 will automatically download but not automatically install).  But if you want to get the benefit of a year's worth of improvements right now, go check Windows Update today (hit the Start Menu, All Programs, and select Windows Update).

If in running Windows Update you do not see Windows Vista SP1 listed, there are a number of good reasons for this (eight, in fact -- see the whole list).  Below are a few of the most common reasons why you might not see SP1 on Windows Update:

• You have not yet installed all the prerequisite packages you need for Windows Vista SP1.

We have some information we'd like to share in regards to Windows Vista SP1 and folks running Language Packs. Some of you may have noticed that after installing Windows Vista SP1 on Windows Vista Ultimate - the Language Packs fail to appear on Windows Update (KB947875).

We will be releasing Windows Vista SP1 in two "waves". The first wave will only provide Windows Vista SP1 to Windows Vista Ultimate PCs running the following 5 Languages: English, French, German, Japanese and Spanish. The second wave will follow shortly after - supporting all 36 languages.

For Windows Update, PCs running the 5 initial languages from the first wave only will be provided with Windows Vista SP1. PCs running Windows Vista Ultimate with any of the other Language Packs installed will not be offered Windows Vista SP1 through Windows Update until they are released. Once the Language Packs are released, Windows Vista SP1 will then be offered for installation.

When installing Windows Vista SP1 from the standalone installer, the standalone installer will only install on Windows Vista Ultimate running any of the 5 languages from the first wave. When installing Windows Vista SP1 on Windows Vista Ultimate with a Language Pack that
