I bought a brand new laptop a week ago. It was loaded with windows 7 professional. When I switched on for the first time it didnt have any user account. So I have created an account for myself as administrator user account. Say 2 or 3 days back I have downloaded GTalk and other softwares and installed it using this account. Today when I wanted to uninstall one of the softwares it was showing a popup saying that I dont have system privileges to uninstall the product. I tried to uninstall some other softwares and was shown the same message. I went to control panel and there with my photograph it showed under my username that I am an administrator. But when I wanted to manage my account it was doing nothing when I clicked manage link. Also the same case when I clicked change account type. Two account I have created, one for me and one for my wife. Both I have created as administrator accounts. Now both the accounts are showing as administrator accounts but was not allowing to uninstall. I tried to open eventvwr. But still the same message. Say 2 days before I wanted to give permission to one of my folder. So I have removed all the permissions to all other users and have given my user full permission. But it was not allowing me as there was some conflict in inherited permissions. So I removed inheriting permission. But I didnt see that it was going to reflect the permission through out C: where my folder resides. But I cancelled the operation in between. Does this has got any link with my admin issue. Even then I have given my user with full permissions. My hard drive has got only one drive that is C: where OS is also installed. My HDD total space is 470 GB and total 470 GB was allocated to C: drive itself. Please help me to get my admin rights back in my laptop. Without which I am not able to do much of work !!
