[Hudlug] backing up my laptop

[MICHAEL WEAVER]

When I get Orca working on my laptop, what would you suggest for making 
backups?
My desktop PC running Windows is getting really untidy with bits of 
removed programs stuck under Control pannel, the system doesn't always 
start first time meaning speech stops after I login etc.
When I get Linux speaking fully I would like to be able to keep it a bit 
more tidy.
Don't know if Linux has this same problem where for example you might 
try an application, find it may not work for you and you try and 
uninstall it and it leaves bits behind.
