             Most of you have came across the software which blocks the websites in your office or else in the restricted environment.For doing this there are more third party softwares available in the market most of them are paid and very few are free wares but when we move for free wares these will be less effective than paid ones.So most of them will prefer the paid one.In the very small company or in the home its very difficult to invest money in the paid one in this kind of situation we can make use of  the windows inbuilt restriction. Actually there is no any such kind of facility provided by Microsoft but we are using this as a trick.This can be done by modifying the Host file

How it works
          It is system file by editing this we can retrict the sites which is be to negleted.The information behind this is for example when you are browing the web page first it will search in the host file for the IP of the website if it not found then it will directly refer the DNS server so by this if we are going to provide some false IP for the website so the webpage cannot be diaplayed.So by this we can restrict what ever sites we want without any third party or freeware softwares. So lets see how to do this trick

1.Start ->run -> drivers and select etc and click on the host file

2.Or else Goto the the location c:\WINDOWS\system32\drivers\etc

3.Open the file with a notepad and append the file below the 127.0.0.1  local host

4.Add the IP of your wish and the leave a space and the web address for example you want to restrict the orkut website means 127.0.0.2 www.orkut.com

5.Now the given webpage in the host file cannot be accessed.

Note:To edit the host file you need the admin right of the local system.

Some of you would have heard this word safe mode, If you don’t know safe mode this article would help you to know better. This is the console like thing for you operating system. Lets consider the scenario you have installed one software and its working fine and time later you faced some problem like you pc get hanged and it is occurring often so you want to find why this occurs. In this it’s very difficult to find the root cause for this problem so in this we don’t have any other option to check whether this problem has been occurred regarding that software so in this case we are only one way to find the solution is the safe mode.

Why SAFE MODE

The safe mode is the kernel or else another entry point for getting into the operating system. So the specialty this mode is no windows drivers and other media drivers will work and in this mode the operating system will run only with the very important files which is minimum enough to run the operating system. So I think the answer is very clear for the above scenario so if you don’t face any issue in your safe mode then you can confirm the problem is due to the new installed software or new application. Incase if you face any issues in safe you can move forward with the event viewer logs.

To go the safe mode

1. Power on your system
2. As soon as its getting booted press F9 to enter to the safe mode menu
3. In this you can select weather the last known good configuration or else with the safe mode.

Note: The last known good configuration is the setting save by the system by this it will restore from it memory. This will work better when there is a unexpected power shutdown so at that time some dll files may corrupted. So by this we can repair very small problems.
