This is better than the one that comes with xp or windows 7. Having said that,I don't have the windows 7 versions but I bet they do one. I works while your pc is working and dose a good quick job.

Ez anti virus doesn't stuff up your system or keep asking you stupid questions. It just gets on with doing the job you want it to do. Again I only have the xp version but I have never had a problem with it and neither has anyone I know who uses it.The interface doesn't have many options.Good news if you don't know what you need or don't need.Just install it and let it get on with what you got it to do.

Paint shop pro 10. I find this fit my pc better than photoshop.If you have a state of the art pc or a mac then who knows,maby your better suited to photoshop,as for me paint shop 10 is all I need.It can be a bit heavy sometimes but I can always put the kettle on while it renders somthing. A friend of mine uses paint shop 7,says it dose all he wants.If you you don't need supersonic turbochargedphotoshop, give this a try.

Paragon Partition Manager is good if you use several hard drives or different operating systems on one machine. I don't use the facility to boot from different hard drives ,as you don't need it.It can if it goes wrong cause you problems.But the partition part of it is great and so easy to use.Copy,format,resize.all without any loss of data.
