Reset Windows 7 Rearm Count

An install of Windows 7 without an activation key allows for 30 days of usage.also  This can however be extended up to 120 days by using the below command that is 

 slmgr (Software Licensing Management Tool)

 command to rearm or reset the 30 day trial.

when you enter this command you have to restart the computer so you can stp the windows not genuine error

slmgr /rearm

Remember to run this command, you must right click on cmd and select “Run as administrator” for this to work

 However this can only be done up to 4 times. we can view the number of rearm counts by using the command which displays the current license informationthis exclusive command is usefln when you forget how many times you have used it

slmgr /dlv

Notice the second to last line shows that I only have 1 more remaining rearm, after which the software will expire. However there is a small trick that allows you to reset the rearm count back to 4. To do this you need delete the registry key which contains the Last Rearm Time, however this key can not be deleted or modified during a normal user session.

 To delete the key you will need to run the following commands in the windows recovery console.

reg load HKLM\MY_SYSTEM "%~dp0Windows\System32\config\system"
reg delete HKLM\MY_SYSTEM\WPA /f
reg unload HKLM\MY_SYSTEM

To do this save the above commands to a .bat file ‘reset.bat’ to the C:\ root folder. Restart your computer, pressing F8 to get to the Advanced Boot Options. Select the option toRepair Your Computer. Select your keyboard input method. Login with your login details. In the System Recovery Options menu, select Command Prompt. Now type inC:\reset.bat. (If it says “‘C:\reset.bat’ is not a recognised as in internal or external command” message, then it may be because the  C Drive is bring used as a recovery partition. Try again using D:\reset.bat) If successfully you should get the message 

“The operation completed successfully”. Next reboot your machines.

After rebooting you may get a message stating that this product is not genuine. This can be ignored. Running slmgr /dlv again will confirm that the rearm count has been increased again, thereby giving you another 120 days worth of windows use.

Laptop tracking software: 8 apps to track your lost or stolen PC

Find and retrieve your lost or stolen laptop

By Matt Hanson | Oct 7, 2012, 02.30 PM IST

Track your laptop: 1-4Track your laptop: 5-8All

Losing a laptop through either misplacing it or by theft can be devastating. Not only is the financial loss tough to get over - laptops aren't cheap after all - but the loss of personal files, documents, photos and other data can be even more upsetting.

It can also be potentially very dangerous, as any criminal who snatches your laptop could then have access to your email or online banking accounts, which combined with other personal data on your laptop, could make identity theft easy.

The laptop security and tracking software we're looking at in this group test claims to add an extra layer of security to your laptop should disaster strike. In worst-case scenarios they should allow you to remotely lock down your laptop and wipe sensitive data. However, in the best-case scenario, the software will allow you to track and retrieve your laptop and, if it's been stolen, provide evidence to the police for a conviction.

Can the software we've rounded up deliver on its promises? Lets investigate.

1. EXO5

A business package that's more focused on locking down your data

Price: £309 for 3 years on 25 devices 
Inf www.exo5.com 
Specs: RemoteKill file encryption, drive lock, curfew, geolocation, logs, data export, RiskSense alerts

EXO5 has a small-to-medium business-orientated approach to laptop tracking, but that shouldn't put off home users - especially if you have a number of devices you want to keep track of.

First of all you need to go to the Settings tab and download the Agent Installer, which is a standalone .EXE file that needs to be run on any device you want EXO5 to track. Once done you can view the devices by clicking 'Assets'.

When selecting an asset to track you'll be shown its location on Google Maps, using similar Wi-Fi triangulation technology as the other services we've tested here. It was good, and got the right road, but was a few buildings out when some of its competitors were more accurate. The public IP address is also displayed, along with whether or not the device is connected to the internet.

The Hardware/OS section, lists your devices' hardware configuration, and isn't much use unless you need to see if someone has changed any of the hardware in your laptop. The software tab offers more illuminating details of what programs have been installed on the laptop while Event Log keeps you up to speed on what your laptop's being used for.

Most of these features are geared more towards an individual or company that wants to make sure that a laptop is being used for the right purposes.

Of most use is the incredibly handy RemoteKill option. This enables you to encrypt files and folders remotely if the laptop is stolen. Presets such as 'All Microsoft Outlook.pst files' make it quick and easy to secure important info. You can also add a boot sector lock to shut down the device - and both can easily be reversed if the laptop is recovered.

Verdict: 3.5/5

2. FrontDoorSoftware

A more blatant approach to security

Price: Free (or $30 for a 3-year licence with unlimited location tracking)
Inf www.frontdoorsoftware.com 
Specs: Stolen alert display, remote lockdown, start-up audible prevention alert, send custom text message, geolocation tracking

FrontDoorSoftware is a laptop protection and tracking tool that although free to download, comes with some of the features that we've also seen in paid-for software. While this is a test on how well it protects a laptop, not on aesthetics, there is a noticeable lack of userfriendliness to the program, which could put people off or make relatively simple actions more complicated than they need to be.

A case in point: the installation process includes a slightly bewildering SetLicence window with a number of buttons and text boxes with little to no description of what each one does. Spelling mistakes in the online instructions don't inspire confidence either.

Once installed our laptop had to be rebooted and afterwards sported a FrontDoorSoftware window with a warning that the device was protected, alongside the usual Windows login screen. You can also send a custom message to the screen. However, it also means that thieves know they need to act fast to remove the software.

Your contact information is also displayed in case the laptop is simply lost, so a good Samaritan can contact you to return it.

FrontDoorSoftware uses Wi-Fi positioning technology courtesy of Skyhook (www.skyhookwireless.com) and the results are very similar to GadgetTrak's (p54), with the approximate location just 60 yards out. However, the software runs as a second-user account, so it has an impact on the system's performance.

You can remotely lock the device and mark it as stolen through a web interface, which can only be unlocked with a code.

Verdict: 2.5/5

3. GadgetTrak

Tracks your laptop with half-hour reports and takes sly web shots

Price: $20 (£13) a year 
Inf www.gadgettrak.com 
Specs: Wi-Fi positioning, webcam support, integrated police reports, online dashboard

For a Windows-based laptop the protection involves downloading and installing the software onto the machine and registering it with your GadgetTrak user account. You can then log on to www.trak.me and use the control panel to enable tracking. You'll get email reports every half an hour, with various bits of information helping you locate your laptop.

Arguably the most useful part of the report is the Wi-Fi based location section, which provides you with the latitude and longitude of your device's location based on its Wi-Fi connection, and the networks surrounding it. There's also a handy link to Google Maps with an icon indicating the rough location of your device.

In our tests it offered the approximate location as a couple of buildings down from its actual location. While it's not pin-point accurate enough to go and retrieve your laptop there and then - not that you should attempt to if it's been stolen - it at least gives you an idea of where it is. Occasionally the location would jump around a bit, pointing in roughly the same area but giving the impression the device was being moved about when it wasn't.

The report also includes a snapshot taken with the laptop's webcam, and will hopefully catch the thief using the laptop at that moment. However, you can't choose when to take snapshots and there's no option to change the frequency of the reports.

When turned off, the laptop can't send tracking info, but as soon as it's turned on you'll get a report. While GadgetTrak does not appear in the Windows Start menu or in the system tray, it can be seen in the Uninstall Programs window - though you need an admin password to remove it.

Verdict: 3/5

4. LoJack

Good all-rounder, but unlike Jack - it's almost the master of tracking

Price: £40 for a year 
Inf www.absolute.com/lojackforlaptops 
Specs: Geolocation, remote lock, customised lock-out message, remote delete, Theft Recovery Team

LoJack is definitely focused on home users. This is evident not only in the easy and simple installation, but also by the pop-ups that appear on screen, similar to those found in antivirus suites. Designed to be reassuring - as it tells you your laptop is protected - it's no less annoying as any pop-ups.

Once installed, you need to create an account on the LoJack website, enable geolocation tracking and create a PIN. A map view shows your device's location and there are four tabs that split the planned recovery of your device int locate, lock, delete and recover.

While many services rely on Google Maps, LoJack opts for a map powered by Esri. It looks good but there's no easy way to zoom in to get a more specific idea of where your device is, just a large red dot that for us covered quite a large part of Bath. Those in larger cities may find this service more useful.

Above the map, there's a Device Status that should update itself every 24 hours, so you know that LoJack is still installed. The Lock part of the process requires you to input your PIN, enter a message, then click 'Lock Device'. The locking process isn't instant - it took about 20 minutes for us. When it did we were notified by email. A lock screen appeared - with our message - and the laptop became unusable.

While good, the locking software isn't entirely secure, but there's also support for Intel hardware locking (if your device supports it). Remote deletion of your important data can also be run in the Delete step, while in the Recover section, the laptop can be marked as stolen and a Recovery Team is notified and will begin collecting evidence to hand over to the police.

java code to extract text from pdf files

Today in this article I am going to demonstrate you how to read or extract text from pdf files using java code.

Why do I even need to read the pdf files ?

Okay, suppose you are programming a E-commerce website using java and you need to analyze Invoices of the customers, obviously the Invoices will be saved in the pdf format you need to get a token number of the customer, In that case you can use this program to find the string token.

I am going to demonstrate using the two methods

1) Using the iText Package

2) Using the apache Package

package com.codingsec;
 
import java.io.IOException;
 
//iText imports
import com.itextpdf.text.pdf.PdfReader;
import com.itextpdf.text.pdf.parser.PdfTextExtractor;
 
public class iTextReadDemo {
 
 
    public static void main(String[] args) {
        try {
             
            PdfReader reader = new PdfReader("c:/temp/test.pdf");
            System.out.println("This PDF has "+reader.getNumberOfPages()+" pages.");
            String page = PdfTextExtractor.getTextFromPage(reader, 2);
            System.out.println("Page Content:\n\n"+page+"\n\n");
            System.out.println("Is this document tampered: "+reader.isTampered());
            System.out.println("Is this document encrypted: "+reader.isEncrypted());
 
        } catch (IOException e) {
            e.printStackTrace();
        }
 
    }
 
}

AND THE SECOND CODE USING APACHE

import java.io.*;
import org.apache.pdfbox.pdmodel.*;
import org.apache.pdfbox.util.*;

public class PDFTest {

 public static void main(String[] args){
 PDDocument pd;
 BufferedWriter wr;
 try {
         File input = new File("C:\\Invoice.pdf");  // The PDF file from where you would like to extract
         File output = new File("C:\\SampleText.txt"); // The text file where you are going to store the extracted data
         pd = PDDocument.load(input);
         System.out.println(pd.getNumberOfPages());
         System.out.println(pd.isEncrypted());
         pd.save("CopyOfInvoice.pdf"); // Creates a copy called "CopyOfInvoice.pdf"
         PDFTextStripper stripper = new PDFTextStripper();
         wr = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(output)));
         stripper.writeText(pd, wr);
         if (pd != null) {
             pd.close();
         }
        // I use close() to flush the stream.
        wr.close();
 } catch (Exception e){
         e.printStackTrace();
        } 
     }
}
