TWEAK YOUR COMPUTER..



Registry Hacks to Tweak WindowsMicrosoft Windows offers a feature-rich interface and several customization options that make it one of the most user friendly operating systems in the world. However, computer geeks would still love to hack the Windows Registry so as to add more extra features and functionalities to their operating system.
If you’re one such geek who would like to customize Windows in your own way, here is a list of 8 interesting registry hacks that you need to try:

1. Disable USB Devices:

Disabling USB ports can be a smart idea to add security to the computer. This can be really handy if the computer is on a public place where the chances of virus and other malware infection is really high. You can easily disable access to USB ports with the following registry hack:
  1. Open the Registry Editor (Start -> Run -> Type regedit and hit Enter)
  2. In the registry, navigate to the following key:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor
  3. In the right-side pane, double-click on “Start”.
  4. In the “Value data” field enter 4 and click on “OK”.
  5. Close the Registry Editor and reboot.
To enable USB devices, follow the same procedure as above except in the step-4 enter3 in the “Value data” field.
Works on Windows XP, Vista and 7.

2. Disable Notification Balloons in Windows 7 and Vista:

You can now disable the annoying notification balloons that keeps popping up frequently with warning messages and reminders. Here is a step-by-step procedure to do that:
  1. Open the Registry Editor and navigate to the following key:
    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced
  2. Right-click on the right-hand pane, and create a new “DWORD”.
  3. Rename it to EnableBalloonTips, double-click on it and set the “Value data” to 0. Reboot the computer to see the changes in effect.

3. Add “Recycle Bin” to My Computer in Windows 7 and Vista:

Would you like to add the “Recycle Bin” icon to My Computer so that you need not go back to the desktop to access it when required? Well, here is how you can do that:
  1. Open the Registry Editor and navigate to the following key:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\MyComputer\ NameSpace
  2. Right-click on “NameSpace” and select New -> Key. Name the key with the following name:

How to Create Your Own Customized Run Commands


Create Customized Run commandsThe Run command on Microsoft Windows operating system allows you to directly open an application or document with just a single command instead of navigating to it’s location and double-clicking the executable icon. However, it only works for some of the inbuilt Windows programs such asCommand prompt (cmd), Calculator (calc) etc.
So, have you ever wondered how to create your own customized Run commands for accessing your favorite programs, files and folders? Well, read on to find out the answer.

Creating the Customized Run Command:

Let me take up an example of how to create a customized run command for opening the Internet explorer. Once you create this command, you should be able to open the Internet explorer just by typing ie in the Run dialog box. Here is how you can do that.
  1. Right-click on your Desktop and select New -> Shortcut.
  2. You will see a “Create Shortcut” Dialog box as shown below
    Create customized Run command
  3. Click on “Browse”, navigate to: Program Files -> Internet Explorer from your Root drive (usually C:\) and select “iexplore” as shown in the above figure and click on “OK”.
  4. Now click on “Next” and type any name for your shortcut. You can choose any name as per your choice; this will be your customized “Run command”. In this case I name my shortcut as “ie“. Click on “Finish”.
  5. You will see a shortcut named ie on your desktop. All you need to do is just copy this shortcut and paste it in your Windows folder (usually “C:/Windows”). Once you have copied the shortcut onto your Windows folder, you can delete the one on your Desktop.
  6. That’s it! From now on, just open the Run dialog box, type ie and hit Enter to open the Internet Explorer.
In this way you can create customized Run commands for any program of your choice. Say ff for Firefox, ym for Yahoo messenger, wmp for Windows media player and so on.
To do this, when you click on “Browse” in the Step-3, just select the target program’s main executable (.exe) file which will usually be located in the C:\Program Files folder. Give a simple and short name for this shortcut as per your choice and copy the shortcut file onto the Windows folder as usual. Now just type this short name in the Run dialog box to open the program.

ENJOY>>>>>

WINDOWS 7 COMMANDS FOR ADMINISTRATOR.


1: System File Checker
Malicious software will often attempt to replace core system files with modified versions in an effort to take control of the system. The System File Checker can be used to verify the integrity of the Windows system files. If any of the files are found to be missing or corrupt, they will be replaced. You can run the System File Checker by using this command:

sfc /scannow

2: File Signature Verification
One way to verify the integrity of a system is to make sure that all the system files are digitally signed. You can accomplish this with the File Signature Verification tool. This tool is launched from the command line but uses a GUI interface. It will tell you which system files are signed and which aren’t. As a rule, all the system files should be digitally signed, although some hardware vendors don’t sign driver files. The command used to launch the File Signature Verification tool is:

sigverif

3: Driverquery

Incorrect device drivers can lead to any number of system problems. If you want to see which drivers are installed on a Windows 7 system, you can do so by running the driverquery tool. This simple command-line tool provides information about each driver that is being used. The command is:

driverquery

If you need a bit more information, you can append the -v switch. Another option is to append the -si switch, which causes the tool to display signature information for the drivers. Here’s how they look:

driverquery -v

driverquery -si

4: Nslookup

The nslookup tool can help you to verify that DNS name resolution is working correctly. When you run nslookup against a host name, the tool will show you how the name was resolved, as well as which DNS server was used during the lookup. This tool can be extremely helpful when troubleshooting problems related to legacy DNS records that still exist but that are no longer correct.

To use this tool, just enter the nslookup command, followed by the name of the host you want to resolve. For example:

nslookup dc1.contoso.com

5: Ping

Ping is probably the simplest of all diagnostic commands. It’s used to verify basic TCP/IP connectivity to a network host. To use it, simply enter the command, followed by the name or IP address of the host you want to test. For example:

ping 192.168.1.1

Keep in mind that this command will work only if Internet Control Message Protocol (ICMP) traffic is allowed to pass between the two machines. If at any point a firewall is blocking ICMP traffic, the ping will fail.

6: Pathping

Ping does a good job of telling you whether two machines can communicate with one another over TCP/IP, but if a ping does fail, you won’t receive any information regarding the nature of the failure. This is where the pathping utility comes in.

Pathping is designed for environments in which one or more routers exist between hosts. It sends a series of packets to each router that’s in the path to the destination host in an effort to determine whether the router is performing slowly or dropping packets. At its simplest, the syntax for pathping is identical to that of the ping command (although there are some optional switches you can use). The command looks like this:

pathping 192.168.1.1

7: Ipconfig

The ipconfig command is used to view or modify a computer’s IP addresses. For example, if you wanted to view a Windows 7 system’s full IP configuration, you could use the following command:

ipconfig /all

Assuming that the system has acquired its IP address from a DHCP server, you can use the ipconfig command to release and then renew the IP address. Doing so involves using the following commands:

ipconfig /release

ipconfig /renew

Another handy thing you can do with ipconfig is flush the DNS resolver cache. This can be helpful when a system is resolving DNS addresses incorrectly. You can flush the DNS cache by using this command:

ipconfig /flushdns

8: Repair-bde

If a drive that is encrypted with BitLocker has problems, you can sometimes recover the data using a utility called repair-bde. To use this command, you will need a destination drive to which the recovered data can be written, as well as your BitLocker recovery key or recovery password. The basic syntax for this command is:

repair-bde -rk | rp 
You must specify the source drive, the destination drive, and either the rk (recovery key) or the rp (recovery password) switch, along with the path to the recovery key or the recovery password. Here are two examples of how to use this utility:

repair-bde c: d: -rk e:\recovery.bek

repair-bde c: d: -rp 111111-111111-111111-111111-111111-111111


9: Tasklist

The tasklist command is designed to provide information about the tasks that are running on aWindows 7 system. At its most basic, you can enter the following command:

tasklist
The tasklist command has numerous optional switches, but there are a couple I want to mention. One is the -m switch, which causes tasklist to display all the DLL modules associated with a task. The other is the -svc switch, which lists the services that support each task. Here’s how they look:

tasklist -m

tasklist -svc

10: Taskkill

The taskkill command terminates a task, either by name (which is referred to as the image name) or by process ID. The syntax for this command is simple. You must follow the taskkill command with -pid (process ID) or -im (image name) and the name or process ID of the task that you want to terminate. Here are two examples of how this command works:

taskkill -pid 4104

taskkill -im iexplore.exe
