excuse my English, I install the program for some time on private PCs with great satisfaction, and I wanted to make a request (perhaps useful for many ...)
To manage the entries that start automatically disabled so that once can not be reactivated.
Google Desktop? Try looking in the programs settings to see if something along the lines of "Start with Windows" is enabled
Or go to Start -> Run (just type in the start menu on vista/7) and type "msconfig" with no quotes, then go to startup and see if it listed there as enabled and try disabling it
CCleaner can disable the entries just fine, but some programs are very insistive on being on start up and have all sorts of settings to keep them there
