Most UK businesses have already moved off Windows 10. But roughly one in six devices is still on it, and that remaining group isn't dragging its feet.
For most of them, the hardware physically can't take Windows 11. Windows 11 needs TPM 2.0, an 8th-gen Intel or Ryzen 2000 chip or newer, and Secure Boot. Roughly anything bought before 2018 fails the check. No software fix changes that.
If that's some of your estate, you've got two options, and one gets more expensive every year. Paid Extended Security Updates run about £60 per device in year one. Then £120. Then £240. Skip a year and you pay for it retroactively anyway. Three years in, that's around £400 per machine that still isn't supported at the end of it.
For a lot of SMBs, replacing the hardware now costs less than paying to stand still, especially with Grade A refurbished at roughly half the price of new.
We broke down the full cost, the hardware trap, and the cyber insurance angle most people miss:
