- Restrict the number of start-ups.
- Disable services which one may not require. For example, if your pc is a stand-alone one, there may be sevral services you would never need. Therefore, disable them or switch over to manual mode. BlackViper’s Vista Service Configurations is an excellent guide
- Reducing visual effects (Aero Theme, Transparency or Eyecandy)
- Ensure that boot defragmentation is disabled to reduce usage of resources
- Start » Run » Regedit. Navigate to HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Dfrg\ BootOptimizeFunction . Right click and Modify. Select Y to enable and N to disable. Reboot.
- Disable : “clear page file on shutdown” option. Cleaning the page-file on every shutdown means overwriting the data by zeros, and it takes time.
- To clear/not clear page file you can apply this reg tweak. Back up registry before trying this.
- Start->run->regedit [enter] » HKEY_LOCAL_MACHINE\SYSTEM\ CurrentControlSet\ Control\ Session Manager\ Memory Management
- Setting for Value Data: [0 = Clear Page File Disabled / 1 = Clear Page File Enabled] » Exit Registry and Reboot.
- Defragment frequently. Vista’s in-built defragger is rather slow, you can try SysInternals Power Defragmenter
