There aren’t too many Windows 10 computers or laptops on the market with ARM-based processors yet, but people who have these machines will soon be able to run 64-bit x64 applications on them. Microsoft says it will finally release 64x emulation for Windows Insider testers in November.
Windows 10 has been able to mimic ARM’s 32-bit x86 applications for a while, along with 32-bit and 64-bit applications. Support for x64 emulation will allow these systems to perform a much wider choice of software. As such, ARM-based computers and Windows laptops will have significantly improved utility.
