HyperTerminal is not included in Windows 7 and Vista.
I combined a list of alternative utilities that can be used instead.

First is PuTTy

PuTTy is a terminal program designed  not only for Serial port connections , it can be used to initiate SSH or Telnet sessions.

Download PuTTy from here

Second is Realterm

Realterm is a serial/tcpip terminal program which can be used for , controlling and debugging binary and other difficult data streams. It is far better for debugging comms than Hyperterminal. It has no support for dialing modems, BBS etc – that is what hyperterminal does.

Download Realterm from here

Third is TeraTerm

Tera Term (Pro) is a free software terminal emulator (communication program) for MS-Windows. It supports VT100 emulation, telnet connection, serial port connection, and so on.

Download TeraTerm from here

Alternatively you can use legacy windows XP hyperterm by downloading the following file and extract it in your system32 folder.

In Vista Windows 2008  or Windows 7 when  you right-click the network icon in the navigation area, but it does not take you directly to the Network Connections properties as we are used to in Windows XP 2000 or 2003 .
You can access Network Connections management menu by running ncpa.cpl from run menu or you can create a shortcut that will access those menu by key combination.

To create ncpa.cpl shortcut

• Right-click on the desktop
• Click: New>Shortcut
• Type the location of the item: ncpa.cpl 
  
• Choose a suitable name, e.g. ‘Network Connection’
   
• Right-click on the newly created shortcut
• Select Properties and seek the dialog box called Shortcut Key.
      Simply over-type ‘None’ with the combination that suits you, for example:
      Ctrl +Alt +N.  Start by holding the Ctrl key, ‘None’ should change.
   
• Now by pressing on Ctrl +Alt+N Network Connection Properties will Open.

Creating shortcuts using control panel applets (CPL files) can be be very useful.
Here is a list of common CPL files which can be used.

Although IP v6 is the next thing , if you not going to use it it can be simply disabled.

To disable IP v6 go to Start >Run type ncpa.clp and hit enter.
You will receive your network adapters list.

Press right click and properties on each adapter and remove selection from “internet protocol version 6”

After you remove it run the following command from command prompt :
Remember you must run Command Prompt as administrator

User Account Control (UAC) is a security component in Windows Vista/7 and 2008 .

It allows user to perform tasks with non administrative privileges. Some times the feature need’s to be disabled.

To disable it Click Start>Control Panel>User Accounts
In the User Accounts  window, remove selection from “Use User Account Control (UAC) to help your computer”

Since windows Vista and Windows 2008 when performing some system tasks in command prompt ,
you must run CMD with administrative privileges.

To do that navigate to All Programs>Accessories right click on Command Prompt and chose “Run as administrator”

You can chose Command Prompt to run always with administrative privileges.
To do that navigate to All Programs>Accessories right click on Command Prompt and chose “Properties”
Under properties navigate to “shortcut” and press advanced
Select Run as Administrator and OK.

From now CMD will run always as Administrator

See Export Wireless Settings Profile

1. Open  command prompt with Administrator privileges
2. Type netstat wlan show profile – you will see no profiles defined.
3. Type netsh wlan add profile filename="c:profilesWifiProfile.xml”
4. By default it will add to all user profiles, so everybody on this computer can see this new profile and use it.

Nice and easy way to Export and WiFi lan setting using netsh command on Vista

Unusually Operating System is installed on C drive and whenever you install new program it goes to C:Program Filesprogram name

I is because the default suggested installation path is C:Program Files.
It can cause a problem when C drive is been wrong partitioned and the size of C drive is small
You can use registry to change the default application installation path to for example install in D:Programs,
To set different default installation path, follow the steps bellow:

4. At the right panel, loacate ProgramFilesDir.
   
5. Double click on it to change the value to your desired path. For example, change the value from C:Program Files to D:Programs.
   

To clear user local profile via registry :

1. Press on Start > Run >Regedit
2. Navigate to the following registry key :“HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionProfileList”
3. Under ProfileList navigate to  binary key’s like this :S-1-5-21-3656904587-1668747452-4095529-500
4. On the right side under  ProfileImagePath you’’ll see the username and profile path.
5. Chose the one with the desired user and delete the long reg key like :“HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionProfileList”
