The growth of mobility means that people need to access corporate systems in a wider range of locations than ever, but most organisations would prefer this was done from a 'known good' copy of Windows rather than one that could be malware-ridden.
Furthermore, there is an increasing desire to travel light, for example with a smartphone or tablet instead of a notebook, and to borrow a computer on arrival if it is really needed.
The idea of a bootable USB stick isn't new, but Microsoft has added some wrinkles to Windows To Go, Microsoft Services architect Tanya Koval told the TechEd Australia conference, especially from a security perspective.
The recovery key for BitLocker is stored in the organisation's Active Directory as part of the provisioning process.
Windows To Go also uses Secure Boot to protect against firmware malware, a feature supported by all Windows 8 certified hardware.
And to minimise the risk of data leakage, the computer's internal hard drive is taken offline by Windows To Go, and can only be brought online by a user with administrative rights, which should not apply to users in managed environments.
