Disable The Installation Of Applications In Windows Xp

Disable the Installation of Applications in Windows XP

Installing applications on a Windows XP system can cause unexpected software and hardware conflicts, as when a new video game conflicts with a computer’s video card and causes the computer’s display to go blank. This happens not only with applications that a user installs intentionally, but also with malware installed without a user’s knowledge or intent. To prevent such problems, users with administrator rights on a local system can use Group Policy settings to disable the installation of applications in Windows XP.


1. Click Start > Run. This opens the Run dialog box.

2. Type gpedit.msc in the “Open” text box in the Run dialog, and then click the “OK” button. This opens the Group Policy Editor.

3. Click to expand Administrative Templates > Windows Components under the Computer Configuration icon in the left-side navigation panel, and then click to select “Windows Installer.” This opens the Windows Installer view in the right-side pane.

4. Double-click on “Prohibit User Installs” in the right-side pane. This opens the Prohibit User Installs Properties dialog box.

5. Click to select the radio box next to “Enabled,” and then click to select the “Prohibit User Installs” option in the “User Install Behavior” drop-down menu. Click the “Apply” button, and then click the “OK” button to complete the process.
