Microsoft has reacted rapidly to public reports of a zero-day denial-of-service vulnerability in its latest iterations of the Windows client and server operating systems, and is providing customers with guidance on how to block potential attempts to take advantage of the security flaw. In this regard, the Redmond company has underlined that no exploits or attacks have been detected for the denial-of-service (DoS) hole in the Microsoft Server Message Block (SMB) Protocol impacting both SMBv1 and SMBv2 in Windows 7 and Windows Server 2008 R2. However, Proof of Concept (PoC) code was irresponsibly published in the wild, making it extremely easy for attackers to build exploits putting at risk users of Windows 7.
“Microsoft is aware of public, detailed exploit code that would cause a system to stop functioning or become unreliable. If exploited, this DoS vulnerability would not allow an attacker to take control of, or install malware on, the customer’s system but could cause the affected system to stop responding until manually restarted. It is important to note that the default firewall settings on Windows 7 will help block attempts to exploit this issue,” Dave Forstrom, group manager, public relations, Microsoft Trustworthy Computing, revealed. “The company is not aware of attacks to exploit the reported vulnerability at this time.” Read More»

Jason You’ve read the reviews and digested the key feature enhancements and operational changes. Now it’s time to delve a bit deeper and uncover some of Windows XP’s secrets.
1. It boasts how long it can stay up. Whereas previous versions of Windows were coy about how long they went between boots, XP is positively proud of its stamina. Go to the Command Prompt in the Accessories menu from the All Programs start button option, and then type ’systeminfo’. The computer will produce a lot of useful info, including the uptime. If you want to keep these, type ’systeminfo > info.txt’. This creates a file called info.txt you can look at later with Notepad. (Professional Edition only).
2. You can delete files immediately, without having them move to the Recycle Bin first. Go to the Start menu, select Run… and type ‘gpedit.msc’; then select User Configuration, Administrative Templates, Windows Components, Windows Explorer and find the Do not move deleted files to the Recycle Bin setting. Set it. Poking around in gpedit will reveal a great many interface and system options, but take care some may stop your computer behaving as you wish. (Professional Edition only). Read More»

Jason Did you ever encountered any application or program which runs through command prompt only but does not work when you double click on it, this happens when you launch a program which is a console application. Instead when you try to launch it the command prompt window flashes for a second and closes automatically.
What is a Console Application?
A console application is a computer program designed to be used via a text-only computer interface, such as a text terminal, the command line interface of some operating systems (Unix, DOS, etc.) or the text-based interface included with some Graphical User Interface (GUI) operating systems, such as the Win32 console in Microsoft Windows
Console applications for windows could be some additional commands for windows which you may want to integrate with windows and some other programs which are completely console based or which does not have any GUI interface associated with them. Read More»

Jason Here’s a nifty little trick for creating a text file listing of the contents of a folder, without using any extra software. Step one is to note down the path and name of the folder concerned; if it’s a long one, click on the folder icon in Windows Explorer so that it’s displayed in the address box, then right-click on it and select Copy. Now open a command window by going to Run (XP) or Search (Vista) on the Start menu and type ‘cmd’
A DOS like window opens and at the flashing prompt type cd then a space and type in the path and name of the folder – in my example the folder is called ‘Pix’, so the first line looks like this:
cd C:\Pix
If you used the Copy trick simply right-click on the flashing prompt and select Paste.
Now press Enter and the cd (change directory) command changes the display to show the path and name of your folder, thus: Read More»

Despite all its quirks, Windows does do some things for a good reason. Some files need to be locked down when they are in use, otherwise you risk damaging the file or harming the Operating System. Unfortunately Windows XP seems to be plagued by files that cannot be deleted. These are frequently simple files like videos (AVI), MP3s or other seemingly harmless files. You try to delete the file, Windows waits a few seconds before announcing that access is denied, the file is currently in use and cannot be deleted. However, you know it’s not in use and you just want it deleted.
If you have encountered this problem, here is a step-by-step process for trying to purge the files you can’t delete. It starts with the basics for Windows XP and moves on to more involved tricks. The process will work for all recent Windows releases, but Windows XP has been causing the most the problems, so we will focus on it. Please note: we are assuming that the file is not crucial to the operation of Windows – deleting important system files can cause havoc. Read More»

Windows Vista can be completely killed by pressing a simple combination of just two keys. All you need to crush Microsoft’s latest operating system and put the much-applauded Wow at an end is two fingers. This issue has been reported independently of Microsoft, and the Redmond company has failed to issue any official comment at the time of this article. The immediate question which comes to mind is if the problem is a security vulnerability or a simple bug.
Either way, you too can watch Windows Vista die in front of your eyes. To make matters worse, the key combination is one of the most utilized keyboard shortcuts in Windows. Pressing the Windows key together with “E” will start Computer in Windows Vista. Keeping the two keys pressed will open a large volume of Computer windows. Want to crush Windows Vista? Nothing could be simpler. Just keep the two keys pressed for more than 20 – 30 seconds. Read More»

If you try to run an old DOS game on Vista, you’ll probably get an error “This system does not support fullscreen mode.” Fortunately, this isn’t a dead end. Download a copy of DOSBox, the greatest MS-DOS emulator for any platform (Windows, Linux, Mac OS X, and more), and try running your game under DOSBox. Not only will you get support for old-school graphics like CGA and EGA, you can even run it in a window!
