Windows 7 Service pack 1 (SP1)

The first service pack for Microsoft’s operating system Windows 7, known as Windows 7 SP1 or Windows 7 Service Pack 1 is now available . The service pack was  released on February 22 to the public. Microsoft will make it available via Windows Update and the Microsoft Download Center.

Windows 7 SP1 is a rollup of security patches, minor bug fixes along with a few tweaks that improve features that were already present when Windows 7 first shipped in late 2009.
Nearly all these updates had been made previously available as individual hot fixes and patches.

Things that you should do before installing the operating system update:

• Scan the computer for malware and viruses. Make sure your antivirus software is up to date before doing so.
• Update device drivers if available to make sure the devices are compatible with the service pack
• Backup your important data and files prior to updating to service pack 1.
• Connect a mobile computer, laptop, netbook or notebook to a power outlet before you start the installation of the service pack.
• Make sure you have enough free disk space available for the service pack (see requirements for additional information).
• Microsoft recommends to disable antivirus software during installation as it can interfere with the installation.
• Possible file corruptions can be checked with the sfc /scannow command on an elevated command prompt. Users need to have the Windows installation files or DVD at hand in case corrupted files need to be replaced. 

Windows 7 Service Pack 1 System Requirements

If Windows 7 is running on the computer then it is very likely that the service pack 1 will install and run on it as well without problems. The only issue that could arise is that you are running out of disk space.
Service Pack 1 has disk space requirements that differ highly depending on the installation method.
Windows users who update the operating system via Windows Update need an additional 750 Megabytes for 32-bit systems and 1050 Megabytes for 64-bit systems. A stand alone installation, for instance by downloading the service pack via Microsoft’s Download Center, requires 4.1 Gigabytes of date for 32-bit systems and a whooping 7.4 Gigabytes for a 64-bit system.

 

How To Block the Installation of Windows 7 SP1

Microsoft has released the Windows 7 Service Pack 1 Blocker Tool which can be used for that purpose. The toolkit blocks the deployment for a period of 12 months after release of the service pack.
