VIsta x84 Vista x64 what does it mean, 64bit or 86bit


Recommended Posts

yeah I've never understood why they started it calling x86 and x64. x86 = 32bit processor right? and 64 is 64bit processor. The install should really detect what type of processor you have already and recommend but guess that's not the case because of compatibility issues.

x86 refers to the name of the processor family 80x86, the x64 refers to the 64 bit versions of these processors.

They should've put

x86 (32 bit)

x64 (64 bit)

to avoid confusion.

Many people with 64bit hardware choose to install the 32bit version for greater hardware/driver compatibility. Thus the choice.

x86 comes from the instruction set used by the Intel 80286, 80386, 80486 series of processors. The Pentium and Celeron series of CPUs are also continued to offer x86 compatibility.

I'd mention the Intel 8088 but that would just confuse people. There actually was a 8086 CPU too but it was rarely used (I think Compaq had a "Turbo" 8086 PC to compete with the 8088-based IBM PC/XT). That was the days of monochrome amber monitors.

    • The constant interface inconsistencies have nothing to do with anything other than their own negligence and refusal to fix it. They are lazy plain and simple. These UI inconsistencies have been there for years and not one tech at Microsoft has taken the time to fix it. It's unacceptable at this point. They keep overloading the OS with ads and garbage nobody asked for but don't fix the issues they have.
    • Surgie matched da Vinci precision in live trials; Unitree’s DoD listing complicates hospital adoption Teleoperated humanoid robots completed live in-vivo surgery for the first time in medical history, UC San Diego researchers reported in Nature on July 8, 2026 — a proof of concept that could eventually extend surgical care to rural communities, battlefields, and remote settings where surgical specialists are absent. But the specific robot at the center of the breakthrough, the Unitree G1, was added to the U.S. Department of Defense's list of Chinese military companies just 30 days before the paper was published, carries a documented wormable security exploit affecting all units ever manufactured, and continuously transmits sensor data to servers in China without notifying the operator. The achievement is real, and the complications are real. Institutions evaluating this technology need to understand both. https://www.techtimes.com/articles/320157/20260711/humanoid-robots-perform-first-live-surgery-pentagon-flags-hardware-chinese-military-tech.htm  
    • Failed to open \EFI\ubuntu\ - Not found That message keeps popping up every time I boot the computer. Stays there for a few seconds than vanishes and the PC loads Linux Mint, but its really annoying the hell out of me, so, does anyone here know and can tell me how to fix that or get rid of it please? Thank you  
    • It's in fashion to bash Microsoft for even existing. It's getting old fast. People talk like other vendors' products are flawless and without issues.
