Windows 7 Service Pack 1 Beta Leaked Build 7601.16543.100403-1630 v.159

Microsoft continuously improves Windows 7® and Windows Server® 2008 R2 by providing ongoing updates while working with software and hardware vendors to deliver application compatibility and hardware compatibility improvements. Service Pack 1  (SP1) is another vehicle through which Microsoft provides operating system improvements to customers.
SP1 is an update to both Windows 7 and Windows Server 2008 R2 that, along with improvements delivered to users via other channels, addresses feedback from our customers. As with previously released updates, SP1 contains changes that are focused on addressing specific reliability, performance, and compatibility issues, supporting new types of hardware, and adding support for several emerging standards. SP1 also continues to improve upon the IT administration experience. SP1 is not intended to be a vehicle for releasing new features; however, some existing components do gain slightly enhanced functionality in SP1.
Service packs also help ensure that your systems are up-to-date. Updates to the Windows operating system, including updates released with bulletins from the Microsoft Support Response Center, will be reviewed and built only for currently-supported service packs. Installing the latest service pack ensures customers have the maximum support lifecycle for their investment.  Service Pack 1 for Windows 7 and Windows Server 2008 R2 will include previously released updates and will deliver a number of powerful new features for Windows Server 2008 R2 for virtualization and Virtual Desktop Infrastructure (VDI). New techniques in memory management with the addition of Dynamic Memory functionality, as well as the ability to deliver full-fidelity graphic experiences in remote and virtualized environments with RemoteFX™, enable organizations to realize the greatest possible potential from their infrastructure. The resulting increase in efficiency and functionality allows for accelerated server consolidation, a more powerful virtualized desktop infrastructure, and an increased return on technology investments.

The impact of SP1 on the Windows 7 client operating system is considered to be minimal. Included changes are expected to address minor usability issues in specific scenarios, as outlined in this document. While Microsoft always recommends that users deploy the latest service pack as quickly as possible in order to maintain the best levels of support, security and user experience, we are strongly recommending to customers and partners that deployment of SP1 should not be considered a blocking issue for the adoption of Windows 7.  In other words, organizations do not need to wait for SP1 to begin receiving the value of Windows 7 today as we don’t anticipate the SP1 for Windows 7 to be substantial.

Interesting but this leak was an Early Pre-Beta-1 with Build String (7601.16543.100403-1630 v.159), which i found really fustrating. After i updating from a leaked build “Full ISO”, microsoft has released for Testers, Early Adopters and Partners.

Leaked file details are as follows.

My Windows 7 ultimate X64, started crashing after the update. Desktop Window Manager crashed in each log on.  When i open up the virtual keyboard, since some times my keyboard has instability, when i tries to close the Virtual Keyboard window, whole window Gets stucked for a while(4,5 seconds). Then suddenly everything gets back to normal. Similar with most of the applications. I think Desktop Window Manager crash might have affected the applications.

I rolled back my installation. But still my Desktop Window Manager is crashing unexpectedly, You have to remember that my system was working perfectly fine until the Service Pack update.  Even after uninstalling the Service Pack same scenario occurs.

Atlast i had to use system restore and restore back to previous state, before i have installed Service Pack 1 – Pre-Beta.

It sucks, such a release will crash Windows 7 completely. i Request microsoft to be careful with such releases.  Even if it was released for Internal Testing and Partners. Such issues are fustrating. Since Windows 7 is gaining a major market share. Microsoft’s one of the best potential product.  Don’t spoil it with such releases of Service Pack 1.

My suggestion is . If you are a potential windows 7 user. As long as your system functioning perfectly, don’t ever try for Leaked builds. Try only Official Release from Microsoft. Even if it is late on release to public.

Please do not download or install such leaked products, it may be contaminated with malware or virus.

Legal Notes: I have obtained this Service Pack-1 release through an online releaser. I tried this service pack to understand what is potentially new in the Service Pack-1.  But my experience was really bad, my exisiting setup was been affected by the “Desktop window Manager” crashing. Even after uninstalling i faced the same.

I would have been happier if i am an official Beta Tester for Microsoft Products.  Because i know what a potential user want’s from an OS or Utilities.

With this post i no way supports piracy or leaking of software builds. All i write is my review about the release.

That’s all for now.
