    In Windows 7, when I go to gpedit.msc, then access the reservable bandwidth for QoS the default would be 20% so I always set that to 0%

    But in Windows 8 the default is 80% ??

    Is the way Windows 8 calculates it the other way round?

    so shall I set that to 100% or 0%? I dont want any bandwidth reserved

    Why are you tinkering with the QoS settings?

    Hello, Intel d00d.

    No, to prevent bandwidth limiting in Windows 8 you should set that option (Limit reservable bandwidth) to 0%, then save and reboot.

    I thought that was on Windows 7?

    If you read the description in Windows 8 under QoS, doesn't it say the opposite?

    You are correct but it hasn't changed in Windows 8.


    The description says what it does. Disabling or not configuring it will set the limit to 80%. Enabling and setting it to 0 will remove the limit.

    The description does indeed say what it does. Let's parse the English, shall we?

    So, right off the bat, we know what this setting does: It specifies the percentage that the SYSTEM can have. Not the QoS packet scheduler, THE SYSTEM.

    An iteration of what this setting does: It specifies the limit of bandwidth the system can reserve (as opposed to what THE PACKET SCHEDULER can reserve) for ALL PROGRAMS.

    The default is 80%, and 80 is even prefilled into the text box. By default, the system has 80% reserved, and QoS has 20% reserved. But somehow, you think that rather than adding 20 to this value, and allowing the system to have a 100% bandwidth reservation, we should instead subtract 80, giving the system 0% bandwidth reservation.

    In other words, you think that QoS is, by default, reserving only 20% of bandwidth for the system, and reserving 80% for itself.

    Seriously?

    Yet another iteration. The text box lets you specify how much bandwidth THE SYSTEM can use, not how much THE PACKET SCHEDULER can use.

    Happily, Windows detects absurd values, and ignores them. That's why you won't see your connection suddenly die if you take bad advice and set this to 0%.
