Windows Media Center is a version of XP Home and therefore does not have the security tools and options and availability of settings and controls that XP Pro has which limits your choice to making him a limited user.
Go to the control panel, click on "User Accounts" and change his account to a limited user, require passwords for all accounts and give each user a limited account.
You also should set up a new limited account for yourself as well for use while on the internet.
You should actually have two accounts even if you are the only one using the computer -
One account with administrator rights, and one limited user account.
An account with administrator rights should never be used for surfing the internet as any malware that may be accidentally or inadvertently downloaded while using an account with administrator rights will then have the unlimited rights of that account to infect your computer.
It enables malware to change settings, run all programs, install or infect all software and access all data including passwords and financial records.
Setting up and using limited user accounts in Windows XP will keep some spyware at bay because XP's limited user accounts do not have permission to
install new software or do anything else that a limited account cannot do.
