I agree with you that an Administrator should be able to do whatever he wants
to do with his computer. I happy to get reminders, requests for
confirmation, or restricting what non-administrator users can do, but I
believe I should have full control of my computer and not be "denied access"
just because MSFT decided they want to restrict my activities. I challenge
MSFT to let Administrators have full access and control of their computers
without having to jump through hoop after hoop.
Specific Hoops You Can Jump Through:
Take Ownership/Permissions
Even running as Administrator may leave you without permissions to modify
some files or folders, even ones that you have just downloaded and installed.
To access or modify (copy, delete, rename) files or folders you can take
Ownership of (in your Username) and grant yourself Full Control permissions
of the files or folders in question described in the following tutorial.

To avoid having to do this individually for hundreds of files, Take
Ownership of large branch folders (or even whole drives) like Program Files
folder, Users folder, or Windows folder, and grant yourself Full Control of
the "folder, all subfolders, and all files" contained in the folder. In the
case of Program Files, you would have full access to all your programs. In
the case of Users folder, you would have full access to your Music, Pictures,
Videos, Documents, etc. In the case of Windows folder you would pretty much
have full access to your OS, including Windows Installer. These folders are
all major branches of your C:\ drive that can be accessed by clicking on
Computer->C:\. Unfortunately, there may be some system files and folders
that will still deny you access; in this event, you can access them from the
Command Line in a Command Prompt box with Run As Administrator selected.
Windows Explorer Run As Administrator
Another way to gain access to modify files and folders includes going to the
Start button, typing in Windows Explorer, right-clicking on this and
selecting Run As Administrator. You should then have "elevated privileges"
to do whatever you wish to files in Windows Explorer.
Unlocker Program
There is also a program called Unlocker that you can use to gain access to
modify files and folders.
