Businesses are finally migrating in numbers from Windows XP to Windows 7, and 42 per cent of PCs worldwide are expected to run Microsoft's latest operating system by the end of the year, according to Gartner.
The analyst firm also forecast that 94 per cent of all new PCs shipped this year will have Windows 7 installed.
However, Gartner research director Annette Jump told V3 that certain territories, including western Europe, might be slower to deploy Windows 7 owing to economic uncertainty.
Gartner research has shown that 89 per cent of large enterprises in western Europe were still using Windows XP at the end of 2010, but this figure is expected to decrease by roughly 35 per cent by the end of this year.
Jump explained that five per cent of enterprises were still using the unpopular Vista operating system at the end of 2010, which Gartner expects to decrease by one per cent by the end of next year.
"Migration to Windows 7 started in the second half of last year in the US, but in western Europe it has been more slow and people are still looking at the operating system and testing it," she said.
"In this region, migrations will really kick off at the end of this year and throughout 2012."
Jump advised organisations wanting to switch to Windows 7 to consider issues of application and hardware capability before doing so.
Gartner also assumes that Windows 7 will be the last Microsoft operating system to be deployed fully across corporations.
In the future, more companies will use alternative client computing architectures and eventually move to virtualisation and cloud computing, the firm added.
