It seems Privoxy doesn't play well with Windows 8 (x64 PRO). Desktop apps works well, but various metro-UI apps like the built-in application Store doesn't. Others, like default windows games which using the metro UI (e.g. minesweeper) has various issues, unable to connect to XBOX live account, timeouts. Store either says "there is no internet connection" or just hangs at a white screen or startup screen. Tried with privoxy started as a user mode app or as a service as well, with same results.

    Ok, here is the hopefully more clear description:
    - Version being used: Privoxy 3.0.19 - DL from SourceForge;
    - Operating System / cpu: Windows 8 PRO 64bit, retail; on Intel i7
    - browser: irrelevant;
    - no other proxy runs in tandem with privoxy, Windows 8 PRO 64bit clean install, with default settings: windows built-in firewall on, windows defender on;

    Simple steps to reproduce:
    - start privoxy with default settings;
    - set windows to use privoxy by default (internet options / connections / lan settings)
    - try to access "Store" from the start interface

    Expected: store shows up
    Actual: error screen which says: your PC isn't connected to internet.

    I've attached a log with debug set to 33809, hope that helps.
    Thanks.

    An additional bit of info: like I said, standard browsing on the desktop interface with any regular browser (Chrome, IE10, etc.) works as expected, just Metro UI apps like store, games has this kind of connectivity problem.

    It seems solved:
    Metro-style applications run inside isolated processes known as “AppContainers,” and by default, AppContainers are forbidden from sending network traffic to the local computer (loopback).
    That's why they couldn't reach the net trough privoxy which listens on a loopback address (127.0.0.1).

    I don't know if this will work , I haven't tried it because I can't get privoxy to start with Windows 8 .

    Configure Proxy server using netsh
    Open a command prompt as administrator
    type Netsh winhttp import proxy source=ie
    restart the computer
    or
    run gpedit.msc
    go to Computer Configuration >Administrative Template>Network>Network Isolation
    Double click on Internet proxy servers for apps or click on edit setting
    The internet proxy server for apps window will open, click on ENABLE
    then enter the proxy IP in the Domain proxies box then click on ok and restart the computer .

    Hopefully , if I understood this right , It should force the Metro UI apps to use privoxy .
    I got all this third hand from someone else , and as I stated I have not tried it myself because as of yet I have been unable to get Privoxy to load with Windows 8 at startup and am not doing anything else until I get that figured out .

    Yeah , I got privoxy to tun finally , a conflict with my firewall loading AFTER privoxy. I have now treid those suggestions and it doesn't work . The Metro apps still don't honor the settings and fail to connect .

    I was finally able to get Desktop Apps to work with Privoxy ! I downloaded the Metro UI App loopback enabler utility from
    http://blogs.msdn.com/b/fiddler/archive/2011/12/10/fiddler-windows-8-apps-enable-loopback-network-isolation-exemption.aspx

    Apparently that was originally to get another Proxy to run with Windows 8 apps .
    It enables loopback capability for Metro UI apps , which is disabled by default .
    I just used it to enable loopback for all Metro UI apps , and tested it and they all are working just fine with Privoxy running .
    One issue though , if you install any new apps , you will need to rerun the utility to enable loopback for that app . Not sure if it will work for all apps , but the default ones installed with Windows 8 are all working .
