Excellent
Um, sort of - it is mostly user friendly, but still requires that you know something of the names of the things you are turning off.
By the way, I highly suggest this to eliminate the clutter of processes.
START -> PROGRAMS -> RUN
type in "msconfig" without the quotes and hit OK.
In the window that pops up, click on the STARTUP tab.
This will list most of the things running in the background and will show where the files are located, who they belong to (program-wise), etc...
Look for the items you want to NOT start when Windows boots up:
Note: Things like IEXPLORE.EXE (Internet Explorer) should never load upon bootup... if it is, run a virus/malware check pronto.
Uncheck all the items you want to not start up. If you aren't absolutely
sure what the item is, DO NOT remove it.
Things like Winword, Excel, Outlook, and any other MS Office files are fine to uncheck.
Things like MSMSGS (MSN Messenger), Yahoo, Google - all fine to uncheck.
You don't need ANY of those things to load as the computer is booting up - removing them from startup does nothing to their usability.
When all done, hit OK, then let the computer reboot.
By the way, is this a Toshiba laptop computer? I'm curious because a lot of the processes are specifically for use with one, and if it's not, I can tell you what else you can turn off.
