As a result of feedback, Microsoft has altered its Next-Generation Secure Computing Base (NGSCB) security technology to make it easier to install.
The technology will form part of the vendor's Longhorn operating system (OS), on which chief software architect Bill Gates revealed he was "betting the future of the company", and investing more than $6bn.
Microsoft unveiled NGSCB, formerly codenamed Palladium, in 2002. It originally used a software component called a 'nexus' to shield applications.
This meant when a virus penetrated defences it could be contained solely in that application. A firm needed both updated software and hardware systems to use the component.
However, now Microsoft has changed the technology to create 'secure compartments', rather than protecting individual applications. This means partners spend less time installing the software and configuring systems.
Steve Reynolds, managing director of Microsoft Large Account Reseller Civica Services, believes Microsoft will find it hard to persuade firms to upgrade. But he said it is generally doing a good job on security.
"Increasingly firms are going to have to find a business advantage to upgrade, and there are still a lot that have the ability to upgrade but have not chosen to deploy it, or are just sticking with what they have," Reynolds said.
"But considering that 90 per cent of worldwide desktops are running Microsoft and every hacker/virus writer is trying to get at it, Microsoft is doing well."
Clive Longbottom, service director at analyst Quocirca, said: "Having just one full application go down will still be annoying and hackers will find a way around it.
"But combining NGSCB with other technology, as well as specific solutions from firewalls through to application security, resellers should be able to keep up with the hackers.
"However, too many firms refuse to take any responsibility for their overall security and are surprised when they get slammed with the latest attack."
