Enhancement

Description

Disk space

PC Health Checkup scans for recoverable disk space in temporary folders, the Recycle Bin, and other locations. You can use the space recovered to store more programs and files.

Startup programs

Most computers have several programs and services that start automatically when Windows opens. Many of these programs and services, including security software, must remain in memory for your benefit. However, computers with limited memory that run too many programs can slow down or become unresponsive. PC Health Checkup can automatically find and delete autostart settings pointing at missing files to help prevent startup problems. If you thoroughly understand how Windows works, you can also choose to adjust other autostart settings.

System registry

The system registry contains all of your Windows and program settings. Unused, broken, or invalid entries cluttering the registry can affect your computer's stability and performance. Sometimes they can even prevent you from installing applications or starting Windows. PC Health Checkup can find and remove unneeded registry entries.

Internet privacy

Websites use small text files called cookies to provide you with customized content or services. Your browser history lets you easily revisit websites. However, someone could also use this information to identify your computer and analyze what you view on the Internet. To help protect your privacy, PC Health Checkup can delete cookies and browser history entries.

Software histories

To help prevent spyware from gathering information about your computer, PC Health Checkup can delete lists of files recently opened by Windows, Microsoft Office software, media players, Windows search, and other programs.

Instant messaging privacy

To help maintain your privacy online, PC Health Checkup can remove chat histories, recent screen names, lists of files downloaded, transaction logs, and other information generated when using Skype, Yahoo! Messenger, and IP Messenger.

What are startup programs?

However, computers with limited memory that run too many programs can slow down or become unresponsive.

How does PC Health Checkup change the autostart settings to improve computer performance?

Autostart settings allow different programs and services to start automatically when your computer does. PC Health Checkup scans these settings and can delete autostart settings related to missing files to fix startup problems.

What changes can I undo after a check up?

You cannot completely undo all of the changes made by the PC Health Checkup. For example, you cannot restore deleted files, cookies, or browser history entries. However, you can recover your autostart settings.
