• Windows location service - How does it compute?

    From VanguardLH@3:633/10 to All on Tue Jan 13 06:53:20 2026
    Windows 10 has its location service, but I'm wondering why enable it.
    It was disabled, I tried enabling it, but it doesn't help finding my
    location. As a test, and after enabling location, I went to Google Maps
    and entered a restaurant some 10 miles away. When I clicked on
    Directions to specify start and end locations, there was a circle icon
    to "Use your location". Clicked on that, and got a prompt "Google Maps
    wants to use your location". In permissions, location is set to Ask. I
    click "Just this time", but the starting point was way way off from
    where I am.

    Because my location was so far off, I have to wonder just how Microsoft
    finds my location other than IP geolocation which doesn't require a site
    to use Windows location services. This is on a desktop PC. No cellular
    radio to connect to a tower. No GPS radio. Just how is Windows
    location going to determine my location? Doesn't seem it has anything
    with which to determine my location other than by IP geolocation.

    Timezone. Really? That's going to track my location? A dozen a-bombs
    could land in the same timezone and never hit me.

    Find my device. Start -> Settings -> Update & Security -> Find my
    device. Other than IP geolocation, how is that going to work on desktop
    PC with no cellular or GPS radios?

    With location and find my device enabled, I go to:

    https://account.microsoft.com/devices

    which says "Unknown - Location data isn't available".

    GPS. No GPS radio in my desktop PC.

    Nearby wireless access points. I have some wifi devices connected to my
    wifi cable modem, but not my desktop PC.

    Cell towers. It's a desktop PC, not a smartphone.

    IP address. Yep, they can use that, but it highly inaccurate. What a
    site would see is the WAN-side IP address specified by my ISP's DHCP
    server for the cable modem which uses a NAT router. With Windows
    location disabled, my IP address is still known. When I use several IP geolocation sites, each gives a different location resulting in a span
    of about a 15-mile radius, or an area of 706 square miles.

    Some folks are paranoid about revealing their location to web sites that
    want it for a service they provide, or to track them. However, for a
    desktop PC, there is no difference when Windows location is enabled, or
    not.

    Seems superfluous to waste CPU cycles on a feature that is ineffective,
    so I disabled it again.

    There was a paper some years ago, where measuring time of flight from
    a large number of test nodes, can narrow your location to around
    two city blocks.

    You can also start doing Bing searches for Joes Pizza, or start
    reading articles off your city hall website, or use the bus schedule
    service at your bus company, and you might (gradually) find they
    have narrowed your location. This is one reason they try to snag
    as many URLs as they can to vortex.microsoft.com , for location reasons.

    Turn on News and Interests and check the Weather widget. It should
    display that it knows where you are. That uses a different location implementation than the generic service used by/for apps.

    And sure, if a GPS is plugged into the computer, Microsoft will read
    out one of the NMEA messages to get a precise location. This is why
    my GPS has only been plugged in on Win7 and Linux. I only intended the
    GPS to be used for the time service.

    AFAIK, Windows Location service exists so *any* program/'app' can try
    to determine your location, i.e. not just web browsers,

    And, as you've found, it can only do what is possible by the - mostly hardware - features of your system. Contrary to populat belief, even Microsoft/Windows can not do the impossible! :-)

    So indeed, if your system doesn't have GPS, Wi-Fi, mobile connection,
    etc, Windows location service can do only IP geolocation, with all its
    inherent limits.

    FWIW, for my Wi-Fi connected system with only a local account (i.e. no location data sent to/from a Microsoft Account) and Location services On
    and On for the app, the Weather app (mentioned by Paul) can not come up
    with *any* location. Good!

    For a desktop, it doesn't.

    I've occasionally had it deduce my location from, I presume, my ISP -
    which has sometimes been tens of miles from where I am, more commonly
    hundreds.

    I've once or twice had something come reasonably close, which is
    startling; I guess that was based on a recent search or similar. But
    that's rare.

    Hang on, I'll just put "where am I" into Google. It says Laceby,
    Grimsby. Grimsby is near Hull on the north-ish east coast of England;
    I'm in mid-Kent, some hundreds of miles to the south.

    That Google search returned many sites with 'where am I' kinds of
    services, but most were cookie-unfriendly (no 'reject all' choice and
    many (tens of) switches were on by default, so too much trouble to turn
    them all off).

    Google *itself* reported my location somewhat accurately, (a few
    hundred metres off) which is understandable, because 1) I do have
    location services on on my (Android) smartphone and 2) now on my laptop
    at home, I'm logged into the same Google Account as the one on my phone.

    So *Google* knows my location (because I allowed it on my phone), but *Microsoft/Windows* has no clue. And that's the way it should be! :-)

    If all you have is a wired connection then I'm impressed it got that close. Mine is hundreds of miles out usually.

    As you say, it's useless.

    Sometimes within 15 miles. Sometimes to another state some city over
    400 miles away. Without GPS, cellular radio, or other means of locating
    my desktop PC, the only means left is IP geolocation. My grocery store,
    for example, thinks I'm 50 miles away, but that varies each time I log
    in. Not until I login can they use my saved address to know which store
    is the appropriate one that is "nearby".

    There is variation and has been for some time...even within one location
    to another.
    e.g.
    Two of my devices Win11 Pro(Laptop), Win10 Pro(Surface tablet)
    - both have Location services enabled, no GPS device, Lan, no Wifi connection
    Win11 - this device's current and exact address in MSFT Weather app,
    exact address in MSFT Find My Device, Google Maps finds my location(but
    its start point is two residences east)

    Win10 - Weather app yields next door neighbor address(~180 ft away), Find
    my Device(other neighbor ~400 ft away in opposite direction)


    Win11 same laptop at relative's home(Location still enabled, their 5Ghz
    wifi) - Weather app(relative address), Find My device(2 blocks away, and
    less than 1/8 mile)

    Note: Internet access on Lan and wifi is the same ISP at all locations)
