Con: Legacy Windows ’Good Enough'

Thanks to myriad cloud services and applications, Windows 7 and Windows 8.1 are just fine for now. ’Can users get what they need done with Windows 7? Absolutely,’ said Todd Swank, senior director of product marketing at Equus, a systems builder based in Minnetonka, Minn.

’Businesses will migrate to Windows 10, but for now most IT managers are saying, ’If it's not broke, don't fix it',’ he said.

For some laggards, Windows XP still suits them just fine. Microsoft, however, stopped support for Windows XP in April 2014. XP is still the third most popular OS with 12 percent market share behind Windows 7 with 61 percent market share and Windows 8.1 with a 13 percent share, according to Net Applications.
