130. Windows Vista Service Pack 1 Update

By Andrew D. Wright

Due to unforeseen circumstances, the Mousepad column #129 was not published in any of the three Weekly newspapers. This column is an update to that column with some new material added.


Microsoft has released the first major revision to the Windows Vista operating system, Service Pack 1. SP 1 can be downloaded as a stand-alone version or as a smaller download through Microsoft's Windows Update site.

Service Packs are major updates to Microsoft software, rolling up months of security updates and program bugfixes into one download. Sometimes new features are added.

Windows Vista Service Pack 1 includes all the security updates and software patches Microsoft has released for Vista since it came out in January 2007. It also fixes some of the more commonly reported bugs with Vista including slow file copying, slow extraction of compressed zip files using Windows Explorer, and poor network performance.

SP 1 improves Vista's hibernation and resume function, and adds battery run time to laptop computers through more efficient processor and graphics usage.

Vista's UAC, the User Account Control watchdog that protects Vista by making the user manually approve any sensitive actions has also been slightly reworked.

Advanced users with the Ultimate and Enterprise versions of Vista may like the new BitLocker disk encryption system. Gamers with the very latest video cards may enjoy the new Direct3D 10.1 update.

Vista SP 1 adds support for some new hardware and software standards not currently in wide use such as Secure Digital (SD) Advanced Direct Memory Access, coming in the next generation of SD host controllers; booting from UEFI (Unified Extensible Firmware Interface), which is set to eventually replace the computer BIOS (Basic Input/Output System - the part of the computer which starts first); and better support for Blu-Ray and HD-DVD optical drives. Support for the next generation of larger size flash memory is also included.

Now the bad news. Vista Service Pack 1 is even less tolerant of older hardware than original Vista. In some cases pre-2007 hardware that would work with Windows Vista will produce system lockups and the famous Blue Screen of Death with SP 1.

Dialup Internet users in particular may want to avoid this update unless their modem has had new drivers written specifically for Vista or Vista SP 1. Many common modems may never get Vista SP 1 support.

If Windows Vista Service Pack 1 does not show up on Windows Update one reason could be an incompatible device or driver that needs to be replaced or updated first.

Be sure to check for the newest drivers for all computer hardware, especially any hardware involving video, graphics, networking or sound. Device drivers written before January 2007 are likely to have problems or not work at all.

Brand-name computers should have driver updates on their websites, listed by computer model number. Other hardware should have driver updates on the individual component maker's website.

Before running the Service Pack 1 update, backup any personal documents or important files to a different device than your hard drive, just in case the update process goes wrong and your Vista hard drive needs to be re-formatted. Be sure to have enough free hard drive space available for the update - up to 15 GB may be needed.

Leave lots of time for the install. A quick problem-free install on a fast computer takes about an hour, but the process can take up to several hours on slower machines. The computer will need to reboot several times during the update and may appear to be not making any progress for long periods of time. Be sure to do the update when there is good weather as a badly timed power outage can make a real mess of things.

After successfully installing Vista Service Pack 1, be sure to check Windows Update for new post-SP 1 updates.
