We as a business loss £1000's of income every year because people use pirated software.
Now apart from it being illegal, there are reasons why you may want to spend a little.
With Pirated software you don't get any support, when it goes wrong you have to sort it out yourself. If you aren't able to or get it wrong you could end up with a box of bits, and some software on it!
We had a call recently from someone who had got hold of a Windows 7 Disc, and installed it. However he had lost everything. During the discussion about what had happened, he stated he had been passed the disc by someone, and theirs had all gone through OK!
Now we have only done 1 job for the customer and his PC is about 5-7 years old. And from memory not that powerfully equipped.
He tried to do an in place upgrade, that having failed, and phoning his Friends he then did a fresh install, reformatted the drive, and then lost all of his data. When I said he was looking at a data recovery job, and that I couldn't say how much of his data we could recover, he decided he would go away and try to reinstall the software again.
Even ignored the warning this would destroy more data??
So you can advise customers, about what they should do, but you can't make them take the advice. This has been a constant theme recently. For us it means eventually the customer will realise they are wrong and then we have to sort the issue out. But if you want advice, actually take the advice and do something about it.
