Few months ago I had blogged the virtual XP mode in the in Windows 7….Where you can use all your real hardware in the virtual mode of XP which was the great facility for us…if also our hardware was not capable to run in the Windows 7 we can easily go to the virtual mode and play the hardware…and I had given the example of my TV card which is compatible with the Windows XP but not with the Windows 7. But the only disadvantage of that virtual XP mode was that it is only accessible to the hardware or processor which support the Hardware-Assisted Virtualization (HAV) technology i.e. Virtualization. And lot of we have to check whether our processor supports the virtualization or not and also some of we may have got this error also.
But now the time has changed, thanks to the Microsoft research team. Who knew this disadvantage and allowed to run the Virtualization beyond the boundaries. Now I don’t need to have the process which supports the virtualization, But simply I need to have a update of Microsoft KB977206 which is available for Windows 7 systems which will remove this prerequisite and the system would be able to run Windows XP Mode and Virtual PC.

Windows live Messenger is one of the worlds's most popular messenger beside yahoo..and google chat...around 320 million active users every month sends 10 billion messages to one another everyday.
Rumor on the market has start to come about the Windows live Messenger Wave 4....Yup it is still not available to download but snapshots are features about this Live messenger start to come out. I have just got the char of comparision of Windows Live Messenger Wave 4 with it’s rival IM client. Hope this will be useful to you guys.

Looking at the present context of Nepal…..there has been a rapid growth in the ICT sector….it’s just booming up. we also can see today most of the professional and student today prefer Laptops rather then Desktop PC’s. it might be due to the irregular flow of current or for easy transportation people prefer Laptops and its market is been increasing day by day…Similarly now the internet has became the basic need of the people….almost every home do have internet connection …..not only that around 75% of people using mobile also use internet in it….so at the moment….hence internet can be considered as the basic need.
To connect the internet we do have now provision of Cable, Optical fiber, ADSL or wireless… but to share internet inside our home we need router….that might be wired or wireless…but looking at the current scenario people prefer the wireless router….ie. Wi-Fi network…..as it is easy to setup for connection….I don’t have to search wire to connect my laptop….also it makes feel free….i.e. i can use while sitting in bed…watching TV can carry my laptop to roof and chat with my friends…no boundary of the wires….if I say the wire router is static…coz i have stay at same place to play with my internet and Wireless is dynamic…I can use wherever I go on range of my router….but getting wireless router means alert in security of private network also…so no one can sneak in my network and sabotage my files.Here I am sharing 10 tips to make your wireless router secure.
-
Change Default Administrator Password as well Username.
At the core of most Wi-Fi home networks is an access point of router. To set up these pieces of equipment, manufacturers provide Web pages that allow Owners to enter their network address and account information(like
http://192.168.0.1). These Web tools are protected with a login screen i.e. username and password. so that only the rightful owner can do this. However, for any given piece of equipment, the logins provided are simple and very well-known(like some router have default username admin and password also admin) to hackers on the Internet. so Change these Settings immediately.

Turn on (Compatible) WPA /WEP Encryption
All Wi-Fi equipment supports some form of encryption. Encryption technolog scrambles messages sent over wireless networks so that they cannot be easily read by humans. Several encryption technologies exist for Wi-Fi today. Naturally you will want to pcik the strongest form of encryption that works with your wireless network. However, the way these technologies work, all Wi-Fi devices on your network must share the identical encryption settings. Therefore you may need to find a “lowest common demoninator” setting.
-
Change the Default SSID
Access points and routers all use a network name called the SSID. Manufacturers normally ship their products with the same SSID set. For example, the SSID for Linksys devices is normally "linksys." True, knowing the SSID does not by itself allow your neighbors to break into your network, but it is a start. More importantly, when someone finds a default SSID, they see it is a poorly configured network and are much more likely to attack it. Change the default SSID immediately when configuring wireless security on your network.
-
Enable MAC Address Filtering
Each piece of Wi-Fi gear possesses a unique identifier called the physical address or MAC address. Access points and routers keep track of the MAC addresses of all devices that connect to them. Many such products offer the owner an option to key in the MAC addresses of their home equipment, that restricts the network to only allow connections from those devices. Do this, but also know that the feature is not so powerful as it may seem. Hackers and their software programs can fake MAC addresses easily.
-
Disable SSID Broadcast
In Wi-Fi networking, the wireless access point or router typically broadcasts the network name (SSID) over the air at regular intervals. This feature was designed for businesses and mobile hotspots where Wi-Fi clients may roam in and out of range. In the home, this roaming feature is unnecessary, and it increases the likelihood someone will try to log in to your home network. Fortunately, most Wi-Fi access points allow the SSID broadcast feature to be disabled by the network administrator.
-
Do Not Auto-Connect to Open Wi-Fi Networks
Connecting to an open Wi-Fi network such as a free wireless hotspot or your neighbor's router exposes your computer to security risks. Although not normally enabled, most computers have a setting available allowing these connections to happen automatically without notifying you (the user). This setting should not be enabled except in temporary situations.
-
Assign Static IP Addresses to Devices
Most home networkers gravitate toward using dynamic IP addresses. DHCP technology is indeed easy to set up. Unfortunately, this convenience also works to the advantage of network attackers, who can easily obtain valid IP addresses from your network's DHCP pool. Turn off DHCP on the router or access point, set a fixed IP address range instead, then configure each connected device to match. Use a private IP address range (like 10.0.0.x) to prevent computers from being directly reached from the Internet.
-
Enable Firewalls On Each Computer and the Router
Modern network routers contain built-in firewall capability, but the option also exists to disable them. Ensure that your router's firewall is turned on. For extra protection, consider installing and running personal firewall software on each computer connected to the router.
-
Position the Router or Access Point Safely
Wi-Fi signals normally reach to the exterior of a home. A small amount of signal leakage outdoors is not a problem, but the further this signal reaches, the easier it is for others to detect and exploit. Wi-Fi signals often reach through neighboring homes and into streets, for example. When installing a wireless home network, the position of the access point or router determines its reach. Try to position these devices near the center of the home rather than near windows to minimize leakage.
-
Turn Off the Network During Extended Periods of Non-Use
The ultimate in wireless security measures, shutting down your network will most certainly prevent outside hackers from breaking in! While impractical to turn off and on the devices frequently, at least consider doing so during travel or extended periods offline. Computer disk drives have been known to suffer from power cycle wear-and-tear, but this is a secondary concern for broadband modems and routers.
If you own a wireless router but are only using it wired (Ethernet) connections, you can also sometimes turn off Wi-Fi on a broadband router without powering down the entire network.
