This document pertains to HP Notebook PCs with Windows 7 and Vista.
Some applications install components into the Windows Startup sequence causing Windows to startup or operate slowly. Some of these applications are poorly written, and others are designed to conflict with other applications or Windows operating system components. Perform one or more of the following procedures to identify and eliminate the applications that have a negative impact on the performance of the computer.
Remove malicious software using anti-virus software
Malicious software consists of viruses, trojans, worms, spyware and adware that have installed themselves on your computer without your knowledge. These types of software files are not easily removed like regular applications using Add or Remove Programs function.
See Related links for more information on viruses, spyware, and the antivirus software installed on your machine.
Remove unwanted startup applications
If Windows is operating slowly, do some diagnostics using the System Configuration utility (MSCONFIG) to identify and remove unwanted programs. Perform the following steps to startup Windows with the minimum required components enabled. Then identify and remove unwanted programs.
- Click Start .
- In the Search field, type: msconfig and when the option appears in the menu, press Enter .
- In the System Configuration window, click the Startup tab.
- Make a list of all the items checked as a startup item.

- Click Apply and allow the computer to restart. Windows Vista will restart with only those programs it needs in order to function running in the background.NOTE:Restarting your computer means that you will lose your place in this help document. You may wish to print this document out before continuing.
When the computer restarts, test the normal computer applications to determine if the PC is operating faster and more efficiently.
- If a needed application does not start, add a check in the box next to the software name and continue the diagnostics.
- Research the applications that did not start, and make sure that they are for programs that you want to have on your computer. You may enable these programs at any time by checking their boxes in the Startup tab, as described above.
Below is a list of known HP tested applications that should not be removed from the Startup list on an HP Notebook PC. Any other applications may be removed to test performance by unchecking the box in front of the application's name.
If you are satisfied with the performance, no additional diagnostics are needed.
