In working with Visa, you always get Alert saying “You don’t have permission to access this folder, click continue to get access”, or “Windows needs your permission to continue” or “Destination Folder Access Denied” or due to security you are not able to save file or change who owned by System…. Lots more. Although you have Administrative privileges still its says sometime “You should have administrative permission”. Or if a program needs Admin permission then you can run that application using “Run as Administrator”!!!!
So we need to do login using Administrator account, but the question is from where?
In Vista, the Administrator (or an administrator) is no longer the most trusted object in the operating system. Yes this is to "ostensibly" protect the system, and is part of a general concept of protecting the integrity of the system. The Administration is not activated and you don’t find any User Interface [Up to now, I didn’t fine] which make it active!!! Does it means you can’t make it Active? NO.
To make it active, you have to run command prompt with Administrator permission. Go to Start –> All Programs –> Accessories –> Command Prompt [right click and RUN AS ADMINISTRATOR]
Write following commands to make Administrator active and set the password.
First command will make Administrator account active and another will set yourpassword as Administration account password. Last command Exit.
Now, reboot or switch user or logoff from current user; you can see it will ask for Administrator account password.
USE AT YOUR OWN RISK.
