I have an oldish laptop running with XP Professional with only 2GB of memory which is virtually full (only ~350MB of space left). The PC is now becoming very sluggish so I am therefore trying to free up some space. I note that there are ~350MB of update files in the C:\WINDOWS\$hf_mig$ directory. I have looked at the comments debating the issue of whether or not it is OK to remove the contents of the $hf_mig$ folder but they seem to date back to 2005 and there does not seem to be a concensus one way or the other. Have there been any further developments since that time?
