IT managers given guidelines to stick with IE6.
Microsoft is reminding IT managers that the scheduled 12 February rollout of Windows Server Update Service will include an automatic upgrade to Internet Explorer 7.
Companies wishing to remain with IE6 have been offered guidelines explaining how to prevent the automated update taking effect.
If the update service is configured automatically to approve Update Rollups, IE7 will be downloaded and installed to workers' PCs when the release becomes available.
IT administrators will need to disable the auto-approval rule before the deadline to prevent the download.
Microsoft claimed that the move was prompted by security concerns.
Many companies will choose to remain with IE6 as some web-based applications experience issues running with IE7.
