Note to readers We've had many enquiries about how to do this. Bear with us, we missed our Boxing Day deadline but are working to bring the answer to you as soon as possible. Reports reached The Register late today that a simple substitution of the Netscape Communicator for the Windows shell would speed up Microsoft's operating system by a factor of ten. Sources close to Microsoft acknowledged it was an easy feat but were unable to explain why this was so. However, the software engineer who alerted us to the switch said the simple fact indicated that Microsoft's claims that its browsers and operating systems were inseparable were spurious. Repeated calls from us to Microsoft Central UK today, were unable to elicit an answer. On Boxing Day (26 December), we shall show how easy it is. ®
