Windows uses 20% of your bandwidth! Get it back A nice little tweak for XP. M*crosoft reserve 20% of your available bandwidth for their own purposes (suspect for updates and interrogating your machine etc..) Here's how to get it back: Click Start-->Run-->type "gpedit.msc" without the " This opens the group policy editor. Then go to: Local Computer Policy-->Computer Configuration-->Administrative Templates-->Network-->QOS Packet Scheduler-->Limit Reservable Bandwidth Double click on Limit Reservable bandwidth. It will say it is not configured, but the truth is under the 'Explain' tab : "By default, the Packet Scheduler limits the system to 20 percent of the bandwidth of a connection, but you can use this setting to override the default." So the trick is to ENABLE reservable bandwidth, then set it to ZERO. This will allow the system to reserve nothing, rather than the default 20%. it works on XP Pro, and 2000 only
Any performance degradation if we were to put reserve as 0? Won't Microsoft reserve it for some reasons?
Same question as wisdom tool, why do they need 20% in the first place, any side effects with changing it
How much does it use in total across the month? I have an 8GB limit and wondering how I can save more of it...
Of course not. It's another dev/null "secret trick for tuning windows" ... 20% is reserved for QoS packages IF the QoS-Scheduler requests bandwidth. If no app requires "priority" bandwidth than all apps using the network simply share the full (100%) bandwidth.

Best trick to speed up your Windows: Use RegEdit and create a new key in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Windows. Make a new DWORD key that you name "SpeedUpMyWindows" and enter a "1" as value.
