How can I run ALL my Apps “as administrator” by default in Windows 7?

You can disable User Account Control (UAC) entirely from the control panel; this will mean all programs (installed, downloaded, background, everything) will effectively run with the privileges you currently have to grant manually (via UAC pop-up or compatibility settings).

I think this is what you are asking for?

However, I highly recommend against doing this; it lowers the security of your entire system by allowing any program to modify your system.

In Windows 7 you can adjust the level of UAC to suit your needs. In descending order of strength, the settings for Win7 are:

• Always notify
  UAC pop-up for changing certain Windows settings and for programs that require elevated rights.

• Notify me only when programs try to make changes to my computer
  Doesn't request permissions when changing Windows settings, they are granted automatically. Programs still require using a UAC pop-up.

• Notify me only when programs try to make changes to my computer (do not dim my desktop)
  As above, but screen is not dimmed. Potentially leaving the UAC pop-up windows open to manipulation by other software.

• Never notify (I suspect this is what you are after, but please reconsider!)
  If logged on as an admin-level user everything is automatically given elevated permissions.
  If you are logged on as a standard-level user, anything that requires elevated permissions will automatically be denied (with no opportunity to enter a password in a UAC pop-up).

1 - Add User To Administrators Group And Remove From Users Group:

1. Log In As Administrator

2. Go To Run ( WinKey + R )

3. Type "control userpasswords2"

4. Select Your Account And Click On "Properties"

5. Select "Group Membership" Tab

6. Select "Administrators"

7. Click OK And OK

2 - Disable Approval Mode

1. Log In As Administrator

2. Go To Run ( WinKey + R )

3. Type "secpol.msc"

4. Go To Local Polices > Security Options

5. Find "User Account Control: Switch to the secure desktop when prompting for elevation"

6. Open It Click Disable It And Click Ok.

7. Restart Computer( Very Important Log Off Doesn't Work )

Now Every App Will Be Run As Administrator In All Administrator Users

You can always just logon as the "Administrator" account.

Or, just set UAC to never prompt you, and then all the apps that need admin rights will get it, without you needing to do anything. Just search for "User Account Control" on the Start Menu.

Just so you know though, this is very dangerous. Any malware will have full admin access!
