Microsoft's free offer to download Windows 10 has now expired but a loophole means that it can still be installed for free, for now at least.
The free download offer ended at 10:59am on 30 July, and should now cost £100 and £190 for the Professional edition.
However, users who tick a box and claim they need the 'assistive features' can still get the installation free of charge.
Microsoft has said there is no deadline for when this version of the update will stop being free, so for now it appears that anyone who missed the deadline to upgrade can still do so.
Microsoft's current figures suggest that 300 million machines now run Windows 10, but this still means that the firm is significantly short of the target of one billion by the end of 2018.
Just a few days later on 2 August, Microsoft will release Windows 10 Anniversary Update, known internally as Redstone (phase one), which adds a whole bunch of new functionality.
This is the evolution of the old-style Service Packs to reflect the new Windows-as-a-service. It will be followed by a second Redstone early next year to tie in with new hardware, after which it is expected that the '10' will be quietly dropped in favour of simply 'Windows'.
Next week's update includes Windows Ink, allowing direct annotation on the screen using a stylus, improvements to Cortana, which now replaces standard search altogether, and a new batch of games using DirectX 12, one of which is racing game Forza Motorsport 6: Apex which will be free to all upgraders.
But not everyone wants to upgrade and, despite reports of buoyant uptake in the SMB sector, there are still a large number of enterprises that simply don't want to, or can't for logistical reasons, take up the offer.
But these customers, for the most part, will be enterprises for which there has been no free offer and so today is just another day in the diary.
Businesses will need to talk to Microsoft about the Enterprise edition as several enterprise features have been removed from the Professional edition, to the chagrin of SMBs everywhere.
