After spending many hours trying to perfect my computer's performance, I have to take it back for repair on Thursday. On Wednesday afternoon I shall be destroying anything which may have personal details. There are a lot of programs with sensitive information, and I will have to uninstall all of them, then wipe free space. I shall then be absent for about 4 weeks. I am devastated!
Make an back-up image on something like Acronis, then wipe the hard drive ( with a hammer) after making sure that you have the programe disk - just in case. I always store any downloaded programs in a folder in 'my documents' so I can find them again without trying to remember where I downloaded them from. I also put all the serial numbers/codes in a Excel file so I can find them again. When the hard drive crashed on my machine last year the back-up proved invaluable - even though it was a month since I had last updated it.
