First i'll start by saying i'm not a new computer user, i dabble in basic programming and i know a wealth of troubleshooting information and can fix most problems on my own. So a couple days ago i started having a very strange problem with permissions. I am the only account on my system and i am administrator. For whatever reason as this account i can no longer: 1. Open files 2. Run programs 3. Copy and paste files/folders 4. Delete files/folders 5. Restart the system 6. Shut down the system 7. Perform run commands from the start menu Also when logging into the computer none of my programs start as they cannot run from the basic GUI (Explorer.exe), so i have to start everything manually through the method described below. I can however open a command prompt and run files directly as well as open the task manager via CTRL+SHIFT+ESC as well as the CTRL+ALT+DEL method (Which is also the only way i can shut down or restart the system. I have all the appropriate permissions for folders and drives. I have all the appropriate permissions for the account. I am a member for all appropriate groups for an administrator. I have run various virus/spyware scans as well as reset my firewall settings to no avail. When booting into safe mode everything runs as normal. Here are my system specs Operating System MS Windows 7 Ultimate 64-bit CPU Intel Core i5 @ 2.27GHz Arrandale 32nm Technology RAM 4.0GB Dual-Channel DDR3 @ 532MHz (7-7-7-20) Motherboard ASUSTeK Computer Inc. K52Jr (Socket 989) Graphics Generic PnP Monitor @ 1366x768 ATI Mobility Radeon HD 5470 Hard Drives 488GB Seagate ST9500420AS ATA Device (Unknown Interface) Optical Drives MATSHITA DVD-RAM UJ890AS ATA Device Audio Conexant CX20671 SmartAudio HD None of these components are to blame as this problem randomly started happening without any updates to hardware or software. I do not have system restore enabled on my system so that is out of the question. This problem started happening while installing Rocketdock and addons. i have already uninstalled all rocketdock software and addons and it did not fix this problem. My best guess is that there is an error somewhere in the registry that i am overlooking. Any help that anyone can provide is appreciated in advance.
