1、在电脑上，安装需要安装类型的软件（绿色软件除外），都需要系统的安装服务Windows Installer才能安装，如果禁用了Windows Installer服务，所有需要安装的软件就都安装不了。

禁用Windows Installer服务的步骤是，先打开“控制面板”，找到“管理工具”这一项，打开。

2、进入管理工具窗口后，选择“服务”这个图标，这个就是进入系统服务的入口，双击打开。

3、来到“服务”窗口界面，向下拖动滚动条，找到Windows Installer这一项，双击打开其属性窗口。

4、在“常规”下，将“启动类型”设置为“已禁用”，然后按下面的“应用”按钮确认设置。

5、然后再在“服务状态”下，点击“停止”按钮，系统就会将“Windows Installer”服务停止，服务状态变为全灰状态，按“确定”退出窗口，禁用Windows Installer安装服务设置完成。
