Windows 7 SP1 System Update Readiness Tool Available

Microsoft is working to make sure that all future service packs, updates and software installations on Windows 7 will integrate hassle-free. The company’s way to ensure that Windows 7 will play nice with the forthcoming Service Pack 1, as well as Windows Update releases, and deployments of third-party software is to resolve any issues in the Windows servicing store which could generate problems for consumers. As far as users of the latest iteration of the Windows client are concerned, they have at their disposal the System Update Readiness Tool for Windows 7.

Microsoft updated the System Update Readiness Tool for Windows 7 on January 2010, and offered the refreshed version this week via the Microsoft Download Center. According to the company, the utility is designed to resolve “an inconsistency was found in the Windows servicing store which may prevent the successful installation of future updates, service packs, and software.”

Windows 7 customers can grab either the 32-bit (x86) or the 64-bit (x64) version of the tool, in accordance with the flavor of the operating system they are running. Although Microsoft doesn’t mention Service Pack 1 for Windows 7, fact is that the company is currently building the first major upgrade for Windows Vista’s successor. The software giant has yet to announce a specific availability deadline for Windows 7 SP1; however, third-party sources close to Microsoft claim that a public Beta will be delivered in April 2010, with the RTM and General Availability dates set for the second half of this year.

“The System Update Readiness Tool verifies the integrity of the following resources: Files that are located under the following directories: %SYSTEMROOT%\Servicing\Packages; %SYSTEMROOT%\WinSxS\Manifests. Registry data that is located under the following registry subkeys: HKEY_LOCAL_MACHINE\Components, HKEY_LOCAL_MACHINE\Schema, HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Component Based Servicing,” Microsoft explained.
