installed windows 7 two day's ago and now i cant change anything. I Want to use team speak and it tells me that i don't administrator rights and now i dont have access to my drive C:/ at all. I cannot open it, it wont let me change administrator rights or ownership rights....

Hi, Are you sure you actually know what you're doing? If you don't know how to change rights (especially administrator rights) then don't touch them. If I were you (which I'm not) I'd reinstall everything in order to make sure no errors remain in the registry or in the file structure. Having said that, Team Speak needs you to have certain elevated rights. Do try to install "as administrator". btw which version of Windows 32 or 64 bits? Give us some feedback and we'll try to help. Cheers Rem

Hi, Is the machine in a domain or a Workgroup? Is your account an administrator account? At this stage, I suggest you perform the following steps to troubleshoot the issue. 1. Temporarily turn off UAC and use the application. 2. Enable the hidden Administrator account in Windows 7 and check the result in the admin account. To enable the hidden account, please refer to the link below: Enable the (Hidden) Administrator Account on Windows 7 or Vista Thanks, Novak
