Microsoft's OS hangover from last year continued to recede this month as uptake of the Windows 10 May 2019 Update (1903) jumped, mostly at the expense of April 2018's code dump (1803).

Figures from ad slingers AdDuplex (based on a sample of 100,000 PCs) show usage of 1903 has crested double figures at 11.4 per cent, up from 6.3 per cent the previous month.
