A few weeks ago I recieved an e-mail inviting me to download and install a free upgrade to NIS 2010. Since I installed the upgrade my PC has become very slow when I first switch on my PC. I have carried out the usual check and I have the minimum files in my start up to aid boot up. But it is still very slow. I purchased 2009 because it was advertised as being a lot faster than previous versions. I wish I had not upgraded to 2010. Can anyone help?
