I did have some problems setting up my new desktop computer; following my feedback at the time, CCL assured me that they will modify the instructions supplied to overcome any difficulties future purchasers may have. Now that I have used the computer for a few months I am absolutely delighted with it. (I upgraded from Windows Vista, so getting used to Windows 10 took a little time, but that was nothing to do with the computer itself). The supplied Microsoft keyboard is a delight to use and both start-up and shut-down are very quick and fan noise is barely perceptible. My main use is for office-based programmes, being involved in the administration of a charity and I would thoroughly recommend this machine.
