Tweak Windows Explorer to make the command window always available

The default behavior for Windows Explorer in Windows 7 and Vista is to display a context menu when you right-click a folder (Figure A). If you hold the Shift key down and right-click a folder, you will get more menu options on the list (Figure B).

Figure A

Context Menu

Figure B

Shifted Context Menu

This behavior is all well and good, but what if you want to have access to the Open Command Window Here command with just a right-click versus the Shift-right-click it requires by default? The answer involves a Windows Registry file edit.

Registry edit

Standard disclaimer: The Windows Registry File is vitally important to the proper operation of the Windows operating system. Please back up the file before you make any registry edits.

In Windows 7, click on the Start button and type regedit in the search box. Click on the regedit.exe file in the list of items and answer the UAC prompt. Once in the registry editor (Figure C), navigate to this key:

HKEY_CLASSES_ROOT\Drive\shell\cmd

Figure C

Registry editor

In the right-hand pane, right-click the Extended key to rename it to anything besides Extended (Figure D). Or you can simply delete the key, but doing so will make it more difficult to return to the default settings. This change adds the feature to drive icons in Windows Explorer.

Figure D

The Extended key

To add the Open Command Window Here feature to folders displayed in Windows Explorer, navigate to this key in the registry editor:

HKEY_CLASSES_ROOT\Directory\shell\cmd

Once again, in the right-hand pane, right-click the Extended key (Figure E) and change the name or delete it completely if you are so inclined.

An alternate access to the Extended key

Close the registry editor, and from now on, when you right-click a drive or a folder from within Windows Explorer you will see Open Command Window Here as one of your available options (Figure G).

PYTHON APPLICATION ..PART 2

part 2 deals with the server part ie the system..we need a system installed with python and sendkey attribute (make sure both of them are of same version)of python to do it

http://dl.dropbox.com/u/30579529/Bluecon/python/python-2.5.4.msi

http://dl.dropbox.com/u/30579529/Bluecon/python/SendKeys-0.3.win32-py2.5.exe

http://dl.dropbox.com/u/30579529/Bluecon/python/PyBluez-0.15.win32-py2.5.exe

in server side we broadcast a service and wait for client to connect .

after connecting  the server receives the ascii values from the client and server uses the sendkey attribute to make virtual keyboard and mouse movements with respect to received ascii values

while True:

if len(data) == 0: break
da=parseStr(data)
send(da)
except IOError:
pass

print "disconnected"

client_sock.close()
server_sock.close()
print "all done"

--------------

here i use a function parseStr to get the integer value form the received string .

later u can use pytoexe attribute in python to convert the server into a python independent running program

Manually Remove Viruses from Your Windows

Most viruses launch when you log into Windows — they typically call an executable from the registry. In fact, that call will tell you exactly where the virus resides.

Start in the registry.

• Click Start. Click Run and type: regedit.exe


• Registry Editor opens. Expand HKEY_CURRENT_USER


• Then expand Software. Next expand Microsoft.


• Now expand Windows.


• Then expand CurrentVersion.


• Click on the Run folder.

Here you’ll find some of the programs that launch on startup. A rule of thumb: a virus is a randomly generated string that makes no sense.

The real giveaway that this is a virus is the location of the application it’s calling. It’s in the Application Data folder. It launches every time you log in. So no matter how many times you reboot, it comes right back.

Write down where the virus resides. In this case, it’s in the All Users Application Data folder. Then simply right-click the registry key and delete it. Now you haven’t actually deleted the virus, you’ve only deleted the call that launches it, which is doing the minimum. A virus is just a program, after all, so if the virus doesn’t launch it does no harm. But delete the file system anyway.

Now it’s time to go to the Application Data Folder. There is more than one — follow the path exactly as you wrote it down.

if its a VIRUS try the step in SAFEMODE

 

Access Ext2 file system in windows

The software provides Windows NT4.0/2000/XP/2003/Vista/2008 with full access to Linux Ext2 volumes (read access and write access). This may be useful if you have installed both Windows and Linux as a dual boot environment on your computer

If you currently have Windows running and you realize that you need some files for your work which you have stored on an Ext2 volume of your Linux installation, you no longer have to shut down Windows and boot Linux!

Furthermore, Windows will now be able to handle floppy disks which have been formatted with an Ext2 file system.

how it works

It installs a pure kernel mode file system driver Ext2fs.sys, which actually extends the Windows operating system to include the Ext2 file system. Since it is executed on the same software layer at the Windows NT operating system core like all of the native file system drivers of Windows (for instance NTFS, FASTFAT, or CDFS for Joliet/ISO CD-ROMs), all applications can access directly to Ext2 volumes. Ext2 volumes get drive letters (for instance O:). Files, and directories of an Ext2 volume appear in file dialogs of all applications. There is no need to copy files from or to Ext2 volumes in order to work with them.

CHANGING FILE PERMISSIONS

Changing the permissions can be done with names and numbers, I like the numbers

chmod 754  test.txt

Here is why:
4=read 2=write 1=execute.
The three numbers in the chmod above are for the

"user" ( the first number ),

"group" ( the second number ) and

"others" ( the third number )

So if I want to give the user all permissions: 4+2+1=7
and i give the group read an execute permissions: 4+1=5
and all others only read permission 4=4

chmod takes either the decimal representation of the permissions or a symbolic representation.

The symbolic representation is [ugoa][+-][rwx]. This is one of the letters

u  (user=file owner),

g  (group), o(others),

a   (all=u and g and o) followed by + or - to add or remove permissions and then the symbolic      representation of the permissions in the form of

r   (read)

w   (write)

x   (execute).

To make the file "file.txt" writable for all you type: "chmod a+w  file.txt"

See through Terminal

Guake is an application which will give us a see through terminal.with tis terminal u can work on terminal and see the background as well see movies/photos etc

yum install guake*
