When I get an e-mail with an attachment for a video, the computer defaults to Real Player. I would like it to go to Windows Media Player. Can you help?
You can set this default, as well as others, as follows: For Windows XP, click Start, All Programs and then click Set Program Access and Defaults.
You'll have four categories of default sets. Click on the Microsoft Windows category to open and set the defaults of various programs to a program included with Windows.
Depending on how you are currently configured, you may also need to click the Custom category to make desired changes there.
For Windows Vista, click the Vista button, and on the right, click Default Programs.
From there you can click "Set your default programs" to see and change any or all of your defaults, or you can click "Associate a file type or protocol with a program" to change just one particular file type.
How do I know which files to delete in my Disk Cleanup? I have numerous temporary Internet files as well as Web client/pub temp files. Also, how do I find out how much free space I have?
The Disk Cleanup tool is a safe way to delete unnecessary files, meaning it will not delete your personal files and/or any file necessary for your system. The categories that come up already checked are safe to delete. The other categories that are left unchecked are safe for delete, but still may be necessary for convenience, such as the Hibernation file and/or Office setup files or Downloaded Program files. I recommend you leave the unchecked categories alone.
To find out how much free space you have on a drive, open My Computer, right-click the drive and select properties.
