To help corporate business users and consumers solve lurking year 2000 problems on their PCs, Microsoft recently began distributing e-mails, postcards and CD-ROMs to millions of registered users.
The correspondence points users to Microsoft's Web site, while the CD includes tools to analyse and fix potential problems.
Microsoft said it will send 22 million e-mails throughout September.
Some 13 million US residents and 9 million international residents will receive e-mails if they registered products after January 1, 1995. More than 36 million people around the globe will receive a postcard.
On the corporate side, by the end of March 2000, the company expects to have sent out 9.2 million CDs. Those include the year 2000 product analyser, which looks for Microsoft products on a PC's hard disk and alerts users to needed patches.
In related news, Microsoft said it has seen an increase by up to 60 per cent month on month of hits on its IT Pro Y2K Web site. As of July 5, the site had served 3.7 million page views to more than 1.3 million users.
