I tried to open Windows Defender to run Software Explorer, to review and edit Startup Programs. Received error 0x800705b4, therefore cannot access Software Explorer.
This system is protected by Microsoft Security Essentials. How should I proceed in my quest to improve performance?
OS is Windows Vista Ultimate 32-bit Service Pack 2, Processor is Intel Core2 Duo CPU - T7500 @ 2.20GHz - 2.20 Ghz - 4.00 GB RAM. System is Dell Latitude D830.
