Here are some ways that may help improve the performance of your Windows Vista/7 PC. If you have the minimum amount of RAM installed these tips should help. Upgrading your RAM to the maximum allowed by the OS and/or motherboard will usually allow you to run some of these features as they are intended.
Adjust visual effects
Optimize performance by changing how menus and windows appear.
Adjust indexing options
Indexing options can help you find what you’re looking for quickly and easily on your computer. You can search more efficiently by narrowing your search to focus on those files and folders that you commonly use. For more information, see Improve Windows searches using the index: frequently asked questions.
Adjust power settings
Change power-related settings so that your computer resumes from power-saving settings more efficiently, and adjust battery usage for portable computers.
Open Disk Cleanup
This tool deletes unnecessary or temporary files on your hard disk so you can increase the amount of storage space you have. For more information, see Delete files using Disk Cleanup.
Advanced tools
Access advanced system tools, such as Event Viewer, Disk Defragmenter, and System Information, that system administrators and IT professionals often use to solve problems. You can also view notifications about performance-related issues and what to do about them. For example, if Windows detects that a driver is reducing performance, click the notification to learn which driver is causing the problem and view help on how to update the driver. Issues listed at the beginning of the list are impacting the system more than issues listed further down the list.
