Tweak #9 - Hibernation
Another really quick and easy tweak - if you're not going to be using Hibernation (as most people don't), make sure it is disabled, as Windows reserves an amount of Hard Drive space equal to that of your RAM for hibernation. To disable Hibernation, go to Control Panel -> Power Options -> Hibernate Tab.
As you can see, for people with larger amounts of RAM, this tweak can free up large portions of space.
Tweak #10 - QoS Tweakage
With Windows XP comes a long acronym - the QoSRRP. This stands for Quality of Service Resource Reservation Protocol. Basically, programs either use QoS APIs and are passed through QoS when trying to access information through whatever bandwidth is available, or they are passed to another API called TCI. One of the differences between QoS and TCI is that it is possible to reserve bandwidth for QoS applications. This is great if you are using QoS applications, but if you don't use any, it means that a percentage (20% by default) of your bandwidth is sitting unused.
To change this, we have to go to Start -> Run..., then type 'gpedit.msc'. Now, open the branches Computer Configuration -> Administrative Templates -> Network -> QoS Packet Scheduler.
Now, double-click the option in the right-hand window 'Limit reservable bandwidth', and then set it to Enabled, and the Bandwidth Limit to 0%.
Now, you should have more free bandwidth to play with (20%, hopefully :).
