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»

Windows vista has lot more to offer when it comes to new features with enhanced user friendliness and other accessibility features being talked about in comparison with other previous versions of windows like windows 2000 and windows xp.Unlike previous Microsoft operating systems, Windows Vista is streamlined specifically according the needs of various types of users.
But when we talk about the resource consumption and their utilization it always need a lot of cpu and other memory to carry out even the simple operations like copying a file ,playing a video as compared to windows xp( Which according to me is the most stable and fast operating system by microsoft ever).
Today I going to share some crucial tips required to make windows vista as faster as windows Xp…
Follow the steps below to make your windows vista faster…
1. Disable the Aero Theme
Aero theme which is wonderful but a slow theme as the graphic effects consume a lot of memory which in turn makes other applications to run slower in vista.

To disable unneeded startup services for a safer, faster XP, use the “Services” Admin Tool (Control Panel > Administrative Tools > Services). If you are a single user of a non-networked machine, you can disable the following items, with no ill effect.
- Alerter
- Clipbook
- Computer Browser
- Fast User Switching
- Human Interface Access Devices
- Indexing Service (Slows the hard drive down)
- Messenger
- Net Logon (unnecessary unless networked on a Domain) Read More»

A DNS server translates a human address like google.com into a numerical IP address so your computer can take you to the right site. Usually, this takes a few hundred milliseconds to complete so it’s barely noticeable, but over time, these milliseconds can really build up. Also, your ISP’s DNS server isn’t always reliable as witnessed by Comcast subscribers recently when their DNS server failed, leaving customers unable to access Google and other sites. By using OpenDNS and FastCache, you can solve the two problems of reliability and speed.
OpenDNS runs a distributed network of DNS servers so using it is more reliable. It filters out bad addresses so phishers and spammers can’t direct you to their site. OpenDNS also detects typos in the URLs you enter so entering craigslist.og leads you to craigslist.org.
A piece of software called FastCache takes care of the problem of speed. It stores the IP address that is returned by your DNS server so your computer doesn’t have to request it every time you want to go to a particular site, saving a few hundred milliseconds each time. Read More»

These days use of torrent has increased tremendously and it is qiute easy also even I prefer torrent to any other site but the problem is that it is slower than other websites. But where there is a problem there is a solution. Following are the 5 ways in which you can speed up your Torrent. Try it!
1. Cap your upload (most important)
Limit your upload speed to approximately 80 percent of your maximum upload rate. You can check your upload speed over here (never trust your isp). Once you know your maximum upload speed, change the max upload (to 80%) speed in your torrent client’s preferences.
Don’t get me wrong, everyone should share as much as possible, but if your upload rate reached it’s max, your download rate suffers significantly.
2. Hack the max TCP connections
If you’re on XP sp2, your TCP connections are limited to a maximum of 10. This seriously hurts your downloading speed because it wont let you connect to a high amount of ip numbers. It is supposed to slow down viruses because their spreading strategy is to connect to a high amount of ip numbers, but it also cripples your torrent downloads. Read More»

Jason Just thought I should give the community my top five list for computer troubleshooting!
1. Your computer isn’t turning on? “Oh, no!” You think, “I’d better get a new one!” STOP right there. Before you get too frustrated, be sure you have checked that the power cord is actually plugged into your wall socket properly. You may think it sounds silly, but believe me, it’s more common than you think even for the computer savvy. If your computer is connected through a power board, you should try plugging it directly into the wall (note for the safety conscious: by plugging the power cable
directly into the wall, you lessen the chance of power failure and damage to your machine). Another reason that your PC may not start is if you have made any repairs or modification to your machine. You may have unwittingly pulled out a connect plug; check all connections.
2. If your computer is starting but is spitting error messages at you, then you might need to take out any memory modules such as RAM and then reset them by plugging them back into different RAM slots.If you get an error such as ‘Unexpected Interrupt in Protected Mode,’ then there is a problem with the settings you have entered in BIOS. To fix it go into BIOS and set it to default settings. If the problem still won’t go away, then you must remove the CMOS chip on your motherboard then put it back in to clean BIOS completely.

Jason At the start of September 2008, Microsoft Technical Fellow Mark Russinovich revealed that he was cooking a major update for Process Monitor, one of the components of the Sysinternals suite. As of September 30, version 2.0 of Process Monitor became available for download. The
description of the tool authored by Mark Russinovich and Bryce Cogswell reveals that Process Monitor 2.0 is designed to integrate seamlessly with both the 32-bit and 64-bit versions of Windows 2000 SP4 with Update Rollup 1, Windows XP SP2, Windows Server 2003 SP1, and Windows Vista.
“Process Monitor v2.0: this major update to Process Monitor adds real-time TCP and UDP monitoring to its existing process, thread, DLL, file system and registry monitoring. You can now see the TCP and UDP activity processes performed, including the operation (e.g. connect, send, receive), local and remote IP addresses and DNS names, and operation transfer lengths. On Windows Vista, Process Monitor also collects thread stacks for network operations,” revealed Curtis Metz, Program Manager, Microsoft Sysinternals. Read More»

TCP/IP, an acronym for Transmission Control Protocol/Internet Protocol, is a suite of protocols supported by Microsoft with the Windows family of platforms. Essentially, through its components, TCP/IP is used for communications on both private networks and on the Internet. As far as the world wide web is concerned, the most common aspects of TCP/IP are IPv4 (Internet Protocol version 4) and IPv6. The Redmond company is offering extensive documentation on TCP/IP as it is supported in Windows Vista, Windows Server 2008, Windows Server 2003 and Window XP. TCP/IP Fundamentals for Microsoft Windows is available for download.
“This online book is a structured, introductory approach to the basic concepts and principles of the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol suite, how the most important protocols function, and their basic configuration in the Microsoft Windows Vista, Windows Server 2008, Windows XP, and Windows Server 2003 families of operating systems,” revealed Keith Combs, Microsoft IT Pro Evangelist, citing an excerpt of the documentation’s description.

Even though Microsoft has promised to drop the prices associated with some of the retail standalone versions of Windows Vista (specifically the Home Premium and Ultimate editions), the fact of the matter is that the SKUs of the latest Windows client will still be far from cheap. In this context, you have to take advantage as best you can of the ecosystem of software solutions built around the operating system. And there are plenty of free offerings that are worth a whole lot more than what you didn’t pay for them. The Sysinternals brand dates back to 1996, and was associated with the Windows operating system from the get-go. The brainchild of developers Mark Russinovich and Bryce Cogswell Sysinternals has become synonymous with a collection of advanced system utilities. Read More»
