Due to the higher security in Windows 2000 and XP, you may not be able to install or run some programs with the standard User account.

By default, Windows 2000/XP does not let a standard user or guest account run programs that access the registry or the operating system files. These programs will work properly if you use a Power User account or an account with higher privileges.

Users are the opposite of administrators. Provided that Windows 2000/XP is clean-installed onto an NTFS partition, the default security settings are designed to prohibit Users from compromising the integrity of the operating system and installed applications. Users cannot modify machine-wide registry settings, operating system files, or program files.

In practice, normal users will not be able to run most legacy applications because most legacy applications were not designed with operating system security in mind. Members of the Power Users group should be able to run such applications.

Power Users are between Administrators and Users in terms of system access. The default Windows 2000 security settings for Power Users are backward-compatible with the default security settings for Users in the Windows NT® 4.0 operating system. In short, Power Users are indeed powerful.

By default, Power Users also have

Modify access to the Program Files directory
Modify access to many locations within the HKEY_LOCAL_MACHINE \Software registry hive.
Write access to most system directories including %windir% and %windir%\system32.
