How dangerous could a batch file be?

What are Batch Files?

Lets do the same thing in an other way. Copy
these three commands in notepad and save file as anything.bat

By default autorun is enabled on windows xp, this puts your pc into potential malaware risk or even virus infection. Mostly, viruses and worms are spread using the windows autorun feature. We should disable autorun on your computers to prevent it from being infected with any virus, malaware or worms. Here are several ways to disable the autorun function:

Disable Autorun with TweakUI.
The most convenient way is to install TweakUI a PowerToy from Microsoft we can download for free . Download TwealUI and install it. This PowerToy gives you access to system settings that are not exposed in the Windows XP default user interface, including mouse settings, Explorer settings, taskbar settings, and more.

1. Run TweakUI
2. Navigate to My Computer -> AutoPlay -> Drives
3. Uncheck the drive you wish to disable the AutoPlay function.
4. Navigate to My Computer -> AutoPlay -> Types
5. Uncheck Enable Autoplay for CD and DVD drives
6. Uncheck Enable Autoplay for removable drives
7. Click Apply button
8. Click OK button

Disable Autorun with Group Policy Editor
If you are a geek type and want to do it the hard way we could use the GPEDIT.MSC tool to disable Autorun. GPEDIT.MSC does not work on Windows Home Edition, only on Windows XP.
1. Navigate to Start -> Run
2. type GPEDIT.MSC
3. Click OK
4. Navigate to Local Computer

Finally, Microsoft releases a successor worthy of Windows XP

For the Windows faithful, it’s been a tough eight years. With the launch of Windows XP in 2001, we thought we were poised on a brink of a new world of NT-based goodness—but two years and uncountable exploits later, the future of Windows was grim. Facing a never-ending torrent of new ‘sploits, worms, and trojans, Microsoft fired back with the single greatest operating system update of all time—Service Pack 2. In the single fell swoop of SP2, Windows XP went from Swiss cheese to secure, and once again we were poised to enter the promised land with… (wait for it)… Vista.

Of course, we all know how Vista turned out. Haunted by poor performance in everything from games to disk access to networking, Vista is widely considered to be Microsoft’s biggest failure. Nonetheless, Vista laid the groundwork for a host of new technologies, all absolutely vital to pushing Windows into the 21st century. Vista’s new, modern driver architecture was designed to move core functionality from the kernel (where any instability can bring down the whole system) to user space—an absolutely necessary development. Likewise, Vista’s proper enforcement of permissions for both users and applications enhanced security, even though UAC remains very annoying. And once vendors fixed their driver flaws and Microsoft squashed some underlying bugs, Vista morphed into an entirely workable operating system, even if we still wouldn’t describe it as “good.”

So, as 2009 draws to a close, we find ourselves testing another new Microsoft OS: Windows 7. Building on the now-mature technologies introduced with Vista, but with a renewed focus on performance and ease-of-use, Windows 7 seems poised to succeed where Vista couldn’t. We’ve finally received a final build of Win7, and have run it through the wringer in both the Lab and in the real-world. Here’s what we found.
