HP PCs - Improving PC Performance (Windows 8)

This document is for HP and Compaq computers with Windows 8.
Use this document to help make Windows and other software perform better. The information below provides ways to improve system performance by making more resources available.
Common causes of slow system performance:
  • Temporary files, cookies, un-cleared Recycle Bin that cause less disk space
  • No free disk space or disk errors
  • Applications that require more system resources
  • Too many tasks running at the same time
  • Nonessential graphic features
  • Not enough memory
  • Overheating due to intensive graphic applications or dust in vent
  • Running anti-virus scan, while other software or applications also run in the background
HP SmartFriend is a support service that can help you troubleshoot slow performance and improve the speed of your computer (only available in the United States and Canada). For more information, see HP SmartFriend (in English).

Use HP Support Assistant to keep your computer running smoothly

HP recommends using HP Support Assistant on a regularly scheduled basis. If HP Support Assistant is not installed on your computer or you are not sure that you are using the latest version, download the current version of HP Support Assistant from the HP website.
If your computer does not support HP Support Assistant, skip to the section Perform system cleanup without using HP Support Assistant for steps that do not involve HP Support Assistant.

Perform system cleanup without using HP Support Assistant

The hard disk drive can have a major effect on system performance. Over time the hard drive can become cluttered with unwanted or temporary files, the data can become fragmented and stored in an inefficient manner, or there might be disk errors on the drive itself. All of these issues can impact system performance, and all are easy to maintain. This section describes methods to maintain hard drive performance through removing unwanted and temporary files, checking the hard drive for errors, and defragmenting the drive.

Perform critical Windows updates

Software and drivers that are out of date can decrease system performance. To use Windows Update to install critical software and driver updates, go to HP PCs - Updating Drivers and Software with Windows Update (Windows 8).

Remove viruses and spyware

If the computer is performing slowly after connecting to the Internet, adware or spyware might be installed. Spyware and adware use the Internet to download and upload data in the background. Some of this data might be sensitive information or unwanted advertising. Removing these viruses will improve the performance of your system.
Your computer might have come with a free trial version of McAfee. If the trial period has ended, your computer might be unprotected. Either choose a new antivirus and uninstall McAfee, or you can activate the full version of McAfee. The computer should only have one antivirus installed at a time. Uninstall one before installing the other.
Scan for viruses and spyware using antivirus or anti-spyware security software. Remove any viruses and spyware found. For more information, see HP PCs - Computer Might Be Infected by a Virus or Malware (Windows 10, 8).

Video about using Windows Defender to prevent virus and spyware problems

Remove any viruses using Microsoft Defender. For more information, go to Using Windows Defender to Prevent Virus and Spyware Problems (Windows 8).

Manage applications to recover from slow system performance

If too many apps or programs are running in the background, system performance can be affected. This section describes different ways to manage which applications or programs are running in the background.

Prevent memory allocation problems

Allocated memory space from software applications that are no longer open can cause problems. Over time, this unused memory space can build up, causing Windows to slow down and use the hard drive more. These memory leaks are causing the system to slow down if the computer runs well when first turned on, but performs noticeably slower after several programs are opened and closed.
Memory leaks can happen when software is closed before it has fully opened. Always allow apps time to fully open before closing them. As a rule, wait five seconds after an app opens before closing it again, even if the app was opened unintentionally.
On rare occasions, an incompatible app might continue to allocate memory while it is running, causing the system to slow down and eventually lock up.
To immediately fix memory leaks, restart the computer. For a permanent fix, isolate software applications that might be causing the leaks.
For information on your computer’s memory requirements, please see the specifications document for your computer model.
To isolate apps that cause memory leaks:
  1. Restart the computer.
  2. From the Start screen, type task manager to open the Search charm, and then select Task Manager from the search results.
    The search for Task Manager
    Task Manager opens.
  3. At the bottom of the Task Manager window, click More details.

  4. Click the Performance tab, and then click Memory to view the amount of available physical memory.
    Performance tab in Task Manager
  5. Click Open Resource Monitor to view how your computer is using the memory.
    Open Resource Monitor
    If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
  6. In the Overview tab, click the arrow to expand the Memory section, and then scroll down to view which apps are using memory.
     Resource Monitor showing memory selection
  7. Open an app suspected of causing the computer to run more slowly.
  8. Check the percentage of Used Physical Memory, and then write it down.
  9. Close and reopen a suspected app repeatedly, and then check the percentage of Used Physical Memory, comparing this number to the one recorded. Each time, wait about 10 seconds before opening the app again.
    • If the percentage of Used Physical Memory continues to increase, there is a memory leak. Contact the software manufacturer for available patches or fixes.
    • If the Used Physical Memory percentage returns to the same numbers or similar each time, the suspected app is probably not creating a memory leak.

Turn off nonessential graphical features to improve system performance

Graphical features and applications can use a lot of system resources and slow performance. Turning off these features can improve system performance. This section explains how to adjust visual effects, such as menu and window graphics, for best performance.
To adjust visual effects:
  1. From the Start screen, type file explorer to open the Search charm, and then select File Explorer from the search results.
    The search field for File Explorer

Reduce heat inside the computer to prevent overheating

Heat buildup can cause problems for any computer. Generally, when temperatures inside the case rise above 35 degrees Celsius (95 degrees Fahrenheit), the risk of damaging important internal components increases greatly. The most common cause of overheating is the accumulation of dust inside the computer. The electrical components in a computer generate heat and fans inside the computer help move the air to keep the components cooled to normal operating temperatures. Inadequate cooling can cause excess heat to build up inside the case which can damage components. The sound of the fan running constantly might indicate that the computer is not running as efficiently as possible and that there is a problem with accumulated dust clogging the air vents.

Adjust System Restore settings

System Restore is a feature of Windows that can revert system software and settings back to a particular date. System Restore does this by saving the changes made to system files in a restore point. System Restore uses up to four percent of the hard drive with restore points if left unadjusted, regardless of the size of the hard drive.
If you are experiencing system problems and might need to restore your computer to an earlier time, DO NOT remove the restore points.
Selecting Turn off system protection will prevent the system from creating future restore points. You cannot restore the hard drive without restore points.
To reduce the space System Restore uses for restore points:
  1. From the Start screen, type file explorer to open the Search charm, and then select File Explorer from the search results.
    The search field for File Explorer
  2. Click the Computer tab, and then click Properties.
    Computer tab with Properties selected
  3. From the tasks pane on the left, click System protection.
    System protection
    If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
    The System Properties window opens with the System Protection tab selected.
  4. Click Configure.
    System Protection tab in System Properties
  5. Reduce the amount of hard drive space the system reserves for system restores by sliding the Max Usage: slider bar to 2%. You can choose a higher or lower percentage depending on how many restore points you want and the capacity of your hard drive.
    Max Usage slider in System Protection
  6. Click OK.
