Does anyone know if this problem has been reported to Microsoft yet?\n\nIt's a VISTA process that deals with microsoft updates. If your PC is\nrunning slow, press CTRL+ALT+DEL, launch Task Manager and check the CPU usage\nof this process. Ridiculous.\n\nIt absolutely kills my PC, mouse clicks take 10 seconds to respond,\nprocessor maxed out, hard disk going like crazy. ALWAYS happens just after\nwindows login for about 5 minutes, then it's fine.\n\n....And my PC is not slow. Intel Quad core extreme QX6950 at 4Ghz, 8GB\nCORSAIR RAM, GeForce 8800 Ultra (Overclocked), 1TB Western Digital SATA HD.\n\nThe TrustedInstaller.exe process needs some serious work.
