XP-Antispy Portable

This is the portable edition of XP-Antispy – a tool that allows you to gain control over your OS’s behavior by enabling you to disable certain functions which slow down your computer or make it prone to virus infections.
Since installation is not necessary, you can store XP-Antispy on a USB flash drive or any other external device, and directly run its executable file on any computer. Thus, the Windows Registry is not updated with new entries and no leftover files can be found on the hard drive after program removal.
XP-Antispy can stop various processes (that are enabled by default) from running on your computer. It has the ability to disable automatic updates and various authentication processes in Windows.
Installation is extremely easy, and the user interface is simple, yet intuitive. The main window is populated with the items that you can tweak; all that remains to be done is navigate the list and check or uncheck the functions in question.
What’s more, you can create multiple user profiles and switch between them rapidly. There are also a few built-in profiles: neutral(almost all tweaks are disabled), suggested (scheme created by the developer) and System Default (undo function for all the tweaks).
Here’s a short summary of the application’s features: you can control the functions in Media Player, such as disabling automatic acquisition of licenses, automatic codec download, sending information about player usage to Microsoft, allowing its uninstall, and others.
Plus, you have control over the network, Internet Explorer (e.g. disable automatic or scheduled updates), services, MSN Messenger, and tweaks. Each option from the list comes with quick information tips at the bottom of the window, in case you have doubts about its role.
Be careful though, as you might tamper with some essential tools for Windows. For instance, you can completely disable the firewall, leaving you unarmed against malicious online threats.
All in all, XP-Antispy is addressed especially to advanced users. The tweaks it provides might seriously harm your computer if you’re less experienced in this area.
