本文介绍如何在Windows Server 2008中禁用用户帐户控制(UAC)，以解决权限被拒绝的问题，并提供详细步骤指导。请注意，禁用UAC会降低安全性。

This article will cover the basics of User Account Control (UAC), which is a new feature in Windows Server 2008 to further control the security of your server.

If you are new to Windows Server 2008, then you are probably wondering why you are getting "Permission Denied " errors when attempting to even open your C drive folder.

To help prevent malicious software from silently installing and causing computer-wide infection, Microsoft developed a feature called User Account Control .

To get around these errors, you can simply disable the "User Account Control: Run all administrators in Admin Approval Mode " security option.

To disable this feature, follow these steps, or simply let us know and we will take care of it for you:

To perform the following procedure, you must be able to log on with or provide the credentials of a member of the local Administrators group.
