prefetch, and then click OK.
Prefetch files are there to help programs load/open quicker but they will be
replaced in prefetch when they are used agªin.
This folder may accumulate useless junk, especially if you change your
configuration a lºt. There's no harm in emptying it. Simply delete all the
files in that folder; Windows will rebuild it as needed

Empty your IE cache and your other temporary file folders, eg: c:\temp,
c:\windows\temp or C:\Documents and Settings\<name>\Local Settings\Temp (the

programmes can be hidden in there - watch out for mysterious *.exe files or
*.dll files in those fºlders.
and c:\Documents and Settings\username\local settings\Temporary Internet
Files\Content.IE5 and delete all the files in those directories and
subdirectºries).
