2004 was a momentous year in many respects. The first crewed private spaceflight took place, NASA flew a Scramjet at nearly 10x the speed of sound, there was an election in the US and an Olympics took place. Not entirely like 2020, then. Windows XP was the world’s most-used operating system, and Microsoft’s Trustworthy Computing (TwC) initiative brought forth Windows XP SP2, which added a ton of security updates brought forward from the Longhorn project.

In a tenuous segue, this leads us to Windows and 2004 in the year 2020 – namely, the release of “2004” build, otherwise known as the Windows 10 May 2020 Update. This is the 10^th major update of Windows 10 – updates which, not unlike the service packs of old, roll-up the fixes of known issues while introducing new features and improving existing ones.

There are quite a few new features and lots of incremental improvements in the May 2020 update; some are fairly minor, others could be more significant – like the many accessibility improvements or improving security with the PUA-blocking feature which could stop the end user from unwittingly installing an app which is not exactly legit but is not exactly malware.

Cortana is getting another reboot, this time as a chat-based assistant, in conjunction with M365;

UK users – after installation, you’ll need to wait for an app update to arrive via the Store, as the Cortana app initially says it’s not available in the UK – though ironically, one of the examples asks for the weather and gets the answer for London… in Fahrenheit…

For an idea of what the latest Cortana invocation will give you, see here.

It might take a little while for 2004 to arrive via Windows Update – it’s a staged rollout, and there have been some reported issues with incompatible drivers, so it may be held back from certain machines until the drivers are updated. See more info on blocked machines.

If you want to force the update to 2004 rather than wait for Windows Update, you can go to the Download Windows 10 page and hit the Update Now button. You might find that the update process goes through a load of downloading and processing, only to tell you that your machine is in a “compatibility hold” because of known driver issues. So you’ll just have to wait…

There are some deprecated and removed features, too, including the Windows To Go ability to run Windows off a portable USB stick.
