What is SP2 and should I install it?
The Microsoft Windows Vista Service Pack 2 (SP2) is a collection of the latest enhancements and improvements in the Vista operating system for your computer. SP2 is a free update and all users are encouraged to install it to keep their computer operating efficiently.
Microsoft is the primary source of information on SP2 issues
When updating your computer to the Windows Vista Service Pack 2 (SP2), the Microsoft web site should be your primary source for information on known issues . When solutions to these issues are developed, Microsoft will publish updates and work-around information.
Where can I find more information before I install SP2?
Important knowledge based (KB) articles available by searching on the www.microsoft.com web site include:
Should I download the SP2 update from a website or use Windows Update?
HP strongly recommends that you update to SP2 using Windows Update . By going through Windows Update, the application will validate that the Vista Service Pack 1 and all of the required drivers and software are installed so that the computer is ready for SP2. If the computer is not currently ready, the Microsoft Windows Update function will provide the required updates and fixes for drivers and other issues to ensure that the computer is ready.
Beginning in mid-May 2009, SP2 will automatically download as a critical update on Windows Vista-based computers that have automatic updating enabled. Using the Windows Update function is the easiest and most convenient way to update a Windows Vista computer.
There is no reason to install SP2 manually. First, that would bypass the Windows Update validation and correction process. The full manual download image is very large. And you would have to search for and manually install all the required hardware drivers. The Windows Update function is programmed to do all that work automatically.
How do I install the Windows Vista Service Pack 2
Before you can install Service Pack 2, you must have installed SP1 and Servicing Stack Update 955430. You may need to run the Windows Update and restart the computer multiple times before the Windows Update will install SP1. HP also recommends that you run HP HealthCheck multiple times as you run the Windows Update. See HP Notebook PCs - Update to Vista SP1 Frequently Asked Questions for additional information about SP1.
There are two ways to obtain the Vista Service Pack 2 from Microsoft:
- Highly Recommended - Use the Windows Update function to install the Service Pack.
- Not Recommended - Manually download the full multiple language Service Pack from the Microsoft Download site, copy it to a DVD, and then install it from the DVD.
HP and Microsoft recommend that you use the automatic Windows Update function. The Windows Update function checks the PC for installed components and software, and then downloads only the required drivers and software. Windows Update also provides you with information if the PC has known software or hardware compatibility issues. The manual installation of SP2 bypasses the software validation and correction process, and you may encounter problems as a result of drivers that have not been updated to work correctly with SP2.
To install SP2 using Windows Update, do the following:
- Connect the computer to a working AC power supply.
- Make sure the PC is connected to the internet.
- Exit all applications and save all files before starting the installation.
- Click Start , All Programs , then click Windows Update .
- In the left pane, click Check for updates .
- Click View available updates .
- In the list select the Service Pack 2 option, and then click Install .NOTE:If the listing for SP2 is not listed, the Windows Update function may have determined that the computer has software that is currently not compatible with SP2, or you might need to install some other updates before installing SP2.
After the update is complete, when you logon to the computer you will see a message stating that the update to Vista Service Pack 2 was successful, or that there was a specific problem that prevented the update.
NOTE:After installing Service Pack 2, you should use HP Health Check to install any updated HP drivers or software, then verify that the computer is operating properly.
Why don’t I see SP2 in the Windows Update window?
SP2 is being distributed gradually by Microsoft, and will be available first in English, French, German, and Spanish. Other languages will become available over time. Continue to check back in Windows Update if you require support in other languages.
Before displaying the option to download SP2, the Windows Update function verifies that Service Pack 1 and Servicing Stack Update 955430 plus all of the required specific versions of drivers are installed on the computer. If the drivers are older than the specified version, Windows Update prompts you to install updated drivers (especially audio drivers) to meet the current requirements.
You may need to run the Windows Update and restart the computer multiple times before the Windows Update will install SP1. HP also recommends that you run HP HealthCheck multiple times as you run the Windows Update.
Only when the Microsoft Windows Update has verified that the required updates are installed and working does it display the SP2 Update option. For more information on why your computer is not displaying SP2 in Windows Update, please refer to the Microsoft web site.
Will SP2 correct all the existing problems with my PC?
SP2 is an enhancement to the Vista operating system and is not designed to solve all the potential problems that users may have with a PC.
To resolve specific issues on your computer, make sure that all drivers and software are up to date. You should launch Help and Support and run the HP Health Check .
Microsoft indicates that Windows Vista SP2 will impact the following:
- SP2 integrates the Windows Vista Feature Pack for Wireless, which contains support for Bluetooth v2.1 and Windows Connect Now (WCN) Wi-Fi Configuration. Bluetooth v2.1 is the most recent specification for Bluetooth wireless technology.
- SP2 improves performance for Wi-Fi connections after resuming from sleep mode. SP2 includes ability to record data to Blu-Ray Disc media.

Go to the HP Software & Driver Downloads page, type the Product number for your PC, select Vista operating system , and check for an updated BIOS. In some cases, if the BIOS is not updated before installing SP2, the PC may fail to start properly.
I did not update my BIOS and now the PC will not boot. What should I do?
When Vista SP2 was released, there were several issues that required the user to update the BIOS or the drivers AFTER Vista was updated. Most of those issues have been corrected because the Windows Update function performs more checks and dynamically downloads the required files. If you encounter a problem after installing SP2, use a different computer to visit the Microsoft and the HP web sites to search for solutions that match the exact startup or no-boot conditions you are experiencing.
Are there any known performance issues with SP2 that require updated drivers?

Why should I set a restore point?
Creating a Microsoft restore point saves a copy of all the system settings. It is a good idea to set a Microsoft Restore Point BEFORE you make any major changes to your computer. If there is a problem with the computer after making the change, you can always reset the system go back to the conditions just before you made change. The Vista Service Pack 2 is well tested, but it is a good idea to create a restore point just in case you encounter a problem.
NOTE:Check the restore settings to make sure the restore point information is saved on the C: drive, never save it on the D:\Restore drive.
If I don't like SP2 can I revert to SP1 or even a pre-SP1 condition by selecting an earlier Microsoft Restore Point?
Depending on conditions, yes! If you must revert to an earlier version, you should uninstall the service pack instead of just using a restore point. You should consider that when you installed a service pack, if there was a limited amount of free space, all previous restore points may have been deleted automatically to reclaim file storage space. In other words you may be able to revert to a point just before the service pack was installed but not to any earlier conditions.
In an extreme case, you can restore the computer to the factory image. Restoring the image erases all the programs and information you have stored on the hard drive. If the recovery partition on the hard drive is not corrupted, you can use the Recovery Manager to restore the factory image. If the recovery partition is not available, you can use the recovery discs that you created to restore the factory image.
I got a message that I have to reactivate my PC. What do I do?
On some retail licensed computers, it may be necessary to reactivate the Windows Vista operating system after installing SP2. If, during the SP2 installation, a device driver is updated that is part of the computer signature, the computer will need to be reactivated. In this instance, you will be prompted to activate your original version of Windows Vista by connecting the PC to the internet and following the on-screen instructions from Microsoft.
NOTE:Read the Windows activation notice carefully. You are being asked to reactivate your original version of Vista using the Product Key printed on the Windows tag on the bottom of your notebook. You are not being asked to purchase a new Product Key.
