I have a question today?
How fussy are you to which Wi-Fi signal you connect? i.e., connecting to an open or a secure Wi-Fi connection.
As we know that most of the Coffey shops and pubs allow you to use the free Wi-Fi open connections. Do you even think twice before connecting to a open Wi-Fi signal?
Please put some time to understand what is the risk involved in using an open Wi-Fi connection.
I know getting internet connectivity when your out and about will look like a blessing. However all your data and your laptop itself can be compromised by anyone connecting to open Wi-Fi connections.
Some people think that having a Anti-Virus program or an Firewall enabled laptop will keep them safe, what they don’t know is when they setup the connection with an open Wi-Fi connection they have already established a trust relation with that router.
Windows 7 gives warning to the user that its very risky to connect to a Open and un-secure Wi-Fi networks yet most of the people I know still connect anyway.
Moreover I know a couple of friends who bought a wireless router and started using it without setting up of security key or changing the default admin password. Read the rest of this entry
Last week I was on a workshop by Microsoft it was for troubleshooting performance issues on Servers.
One of the interesting thing which I came across in the workshop was about the memory management and the way Windows handles the memory.
By default Windows allocate’s virtual address space to User mode and Kernal mode, Windows assumes that it has 4 gb of virtual address space and it splits it into two half.
ie. 2 GB virtual address space to Kernal and 2 GB virtual address space to User
We can tweak it and allocate virtual address space to programs 1 GB to the kernel and to executive component.
This is how you can do it:
First un-hide the hidden files and folder make sure you unhidden the Operating system files too.
on the root directory ie C drive you will find boot.ini file take a backup of it on keep it safe.
Edit boot.ini and add \3GB at the end Read the rest of this entry
