Microsoft has just rolled out a Release Candidate (RC) or Windows Service Pack 1. I have already given direct download links to Windows 7 Service Pack 1 RC. I have also given complete list of hotfixes and updates included in Windows 7 SP1. The only problem with Service Pack 1 installation is its expiration. I have already written about the problems that we may encounter after installing Windows 7 Service Pack 1.
Microsoft will be releasing the RTM (final) version of Service Pack 1 for Windows 7 and Windows 2008 in the first quarter of 2011 and the service pack will be available for installation through Windows update too. Since Windows Update can automatically install the Windows 7 Service Pack 1, the people who don’t want to install it have the option to block Windows 7 Service Pack 1. Microsoft has provided a Service Pack blocker tool for blocking the installation of Windows 7 SP1 through Windows Update. It does a simple tweak by changing a registry value to block SP1.
The Windows 7 Service Pack blocker can be downloaded directly from here.
Otherwise, if you want to manually edit the registry then follow the steps below:
- Open Registry Editor and go to the following key:
- Create a new DWORD value called DoNotAllowSP and set its value to 1
- It requires Windows to be restarted.
