A little more than one year after its release, Windows Vista will receive its first service pack update in March. Microsoft says the pack will offer better compatibility with third-party hardware, increased reliability, tighter security and better performance. But unlike the last Windows Service Pack release, Windows XP SP2 — which offered users a new Windows Firewall, an improved Automatic Updates feature and a pop-up ad blocker for Internet Explorer — Windows Vista SP1 is largely a code update, devoid of new eye candy and very light on 'must-have' features, at least for home users. Most of the features touted by Microsoft are for the Business, Enterprise or Ultimate editions of the operating system. Our advice: wait until Windows Vista SP1 is offered to your PC via Microsoft's Automatic Updates service.
Installation
Windows Vista SP1 will arrive one of three ways. Most users will automatically receive the update via Windows Update. Microsoft says that users will only receive the changes specific for their computer to cut down on network traffic and download times. Users with limited or no internet connectivity, or who need to update more than one PC, will be able to download a complete image of Windows Vista SP1 via DVD. Volume license customers (enterprises) will receive an integrated DVD media package for installation on new PCs.
Before installing SP1, all users running Windows Vista RTM (that is, if you bought your computer with Vista preinstalled) will need to install three updates from Microsoft. Microsoft's Windows Update will automatically detect and install these updates prior to the release of Windows Vista SP1. Two of these updates increase the success rate for installing Windows Vista SP1; one is necessary only if you have Windows Vista Enterprise or Windows Vista Ultimate installed.
All this sounds complicated, but Microsoft says it has learned from Windows XP SP2, an upgrade that sometimes stranded users with long, overnight downloads. Windows Vista is modular, thus the upgrade will download only the chunks of code necessary for your specific system. If you have enabled Automatic Updates, in theory, you should have a much shorter download and installation of the upgrade than someone who hasn't kept up with the numerous updates since Windows Vista's release. Despite the many changes within the code, Windows Vista SP1 does not change the basic hardware requirements for running the different editions of Windows Vista.
Using a disc provided by Microsoft, we found the upgrade of Windows Vista to SP1 on a typical Acer TravelMate required about an hour. During that time, the computer was unusable and automatically rebooted several times. A display informed us exactly where the install was in terms of overall progress (for example, 'Configuring update, stage 1 of 3, 34 percent complete').
Should you, for any reason, want to uninstall this upgrade, Microsoft allows you to do so, although the three preinstallation updates cannot be removed.
Features
Where Windows XP SP2 introduced the Windows Security Center and changed the existing Windows Firewall, Windows Vista SP1 introduces almost no visible change to your desktop. There are no new features to view, with almost all of the nearly 300 changes occurring under the surface, and mostly intended for Business, Enterprise and Ultimate editions.
Specific reliability improvements include the prevention of data loss while ejecting NT file system file-system-formatted removable media; enhancements to TCP/IP Version 6; improved driver sleep and wake-up times; improved Meeting Space connections; improved Remote Assistance applications; it also includes Encrypting File System in the Windows Vista file-backup set.
For performance, Microsoft says SP1 uses less bandwidth when browsing network shares, and automatically selects between wireless and wired when more than one is offered. There are also many tweaks and improvements in ReadyDrive (requires the use of special hybrid drives) and ReadyBoost (requires special USB drives) and SuperFetch (requires a specific amount of RAM). As a result, users currently running Windows SuperFetch will notice, after installing Windows Vista SP1, their system is slower. Microsoft says that's because SP1 erases the existing SuperFetch data. As new data is collected, the system will respond 'within a few days', Microsoft says.
There are many new standards introduced with SP1. For example, there's a new Unified Extensible Firmware Interface, x64 Extensible Firmware Interface network boot, Direct3D 10.1 for 3D gaming, new flash-based xFAT, HD-DVD and Blu-ray drives are identified as HD drives, support for SD Advanced Direct Memory Access, second-generation Windows Media Center Extenders, an enhanced MPEG-2 decoder and enhanced support for Windows Network Projector.
For security, SP1 improves the Bitlocker encryption in Windows Vista Enterprise and Windows Ultimate by adding multifunction authentication methods; moreover, Microsoft now allows encryption support for volumes other than the bootable volume. SP1 also includes some Smart Card enhancements, and allows for biometric, as opposed to PIN, access to Smart Cards. Within Vista, SP1 creates a more secure PIN channel for authentication.
For most users, the new features will have little or no effect on the day-to-day use of their systems.
Performance
In general, we found that Windows Vista SP1 offered a mixed bag of improvements. For example, Microsoft says that reading and writing files will be much faster within Windows Vista SP1. Tests performed on a Dell XPS M1530 notebook showed that performance did improve in one scenario, remained steady in another, and even deteriorated in a third scenario. When transferring files from one folder to another on the same drive volume, the transfer time did somewhat improve. However, when reading those same files from an external drive, or writing them to the external drive, performance was the same or worse.
We did find that common application tasks performed in Windows Vista improved after installing SP1.
Those looking for enhanced battery life under Windows Vista SP1 will be disappointed. Although Microsoft touts its own internal study showing that in 14 out of 16 randomly-chosen notebooks battery life did improve, we were unable to support that in our own testing.
Support
We found that Microsoft offers a reasonable amount of support for the SP1 upgrade. For example, before you start there is a link to a Read Me page called 'What you should know before installing Service Pack 1', which covers what to do before installing, during and after installation. Also, Microsoft has improved the upgrade process itself so that if the installation of one update fails, it tries another while preparing to rerun the failed update. This should speed installation for most users. But if users do run into trouble, they can always uninstall the upgrade.
Conclusion
Do you need Windows Vista SP1? Yes and no. It's always good to install the latest (i.e. patched) code for any operating system. But downloading and installing the update will take some users a few hours without any visible or tangible improvements to their systems.

I was a bit nervous installing SP1 beta on my new laptop as there were plenty of posts on the Microsoft SP1 forums with issues ranging from BSOD to random restarts. In the end I am very glad I did install it.
As the ZDNet review indicates for many people there maybe not much noticeably changed. However, as I use my system several hours every day I noticed quite a few changes and all of them for the better.
Setup is long but straight forward if you follow the instructions.
1) Faster Wifi connections - The time taken to detect and connect to a known hotspot is significantly improved. From taking anything up to a minute to find and connect to my home or office wifi it now takes less than 3 seconds and if you are connecting from boot up it is usually connected before you system can even display the network icon in the taskbar
2) Faster file transfer. After further testing there is significant improvement in file transfer speed on both the same hard drive and when transferring from another SP1 system. Transfer to and from non-sp1 systems and external drives is improved slightly but not enough that you would notice unless you did benchmarks before and after.
3) Now seems to recognise 4GB of Ram on Vista 32bit. Although memory Allocation seems to remain the same with some reserved for use by the OS to enhance certain hardware and therefore not available to the apps running on your system - at least now it does show as a 4GB system in most places such as system properties.
4) Improved Readyboost performance. Read and write times seems to be improved in general so unsurprisingly ReadyBoost performs better. Again it will greatly depend on the quality of your memory stick as to whether this is worth doing. ReadyBoost min req is just a 5mb/s read and 3mb/s write speed. With companies like corsair, lexar and toshiba/kingston offering read speeds in excess 30mb/s and write speeds of upto 25mb/s ReadyBoost is finally worth buying a memory stick for (corsair memory sticks with the "GT" suffix read at 34mb/s and write at 25mb/s). SP1 takes better advantage of these memory sticks as you get better overall transfer speeds and there maybe other tweaks.
5) Mobility Stability - there were often hiccups with going in and out of standby or hibernate on laptops running vista. Sometimes they wouldn't go into standby or would take a long time to do so. Other times they would wake up randomly by themselves and if they were in your bag this was a major problem. I would occasionaly open my bag to find my laptop extremely hot as it had turned on and sat cooking due to the lack of ventilation. Since SP1 standby and hibernate is a lot faster - on most occasions nearly instant. Restoring from sleep states has never failed (so far) and I've not had the random waking that was so annoying before.
6) Hard drive space. I don't know if this was intentional but I actually had MORE hard drive space free after the SP1 update than I did before I started. I expected the opposite so perhaps it removed some unnecessary data. It was only a few hundred megabytes so not a big deal.
7) Thumbnails generated faster. When I open picture folders the images load a lot faster than before. Unless the folder has a very large number of images in the thumbnails seem to be near instant. Even on folders I've not already generated thumbnails for or on memory cards.
8) Video playback is the only area that seems to have reduced performance. DivX video files are sluggish in windows media player and hi-quality/resolution files can even stutter. Playing the same files in another player resolves the issue. Doesn't seem to affect DVD/Blu-ray playback. I suspect there has been an update to Windows Media Player that affects DivX playback.
9) Overall stability is improved with noticeably less appreances of the blue turning circle (formerly an hourglass in XP) and program lockups.
