Protect Your Usb Flash Drive

How to Write-Protect Your USB Flash Drive

USB Write ProtectMany a time, it becomes necessary for us to write protect

our USB flash drive so as to protect it from viruses and other malware

programs. Because flash drives are so popular and most widely used to move

data between computers, they are the prime target for attackers as a means

to get infections spread around the computer world. Also, since USB drive

is not a Read-Only Memory (ROM), the data inside it can easily be modified

or deleted by malware programs.
But unfortunately, most of the new flash drives do not come with a

write-protect feature as the manufacturers wish to cut down the cost of

production. Hence, the only way to write-protect your USB flash drives is

to enable this feature on your own computer.
This can be done by adding a small entry to the Windows registry which acts

as a switch that can be enabled to make use of the write protection or

disabled to allow write access. Just follow these steps:
1. Open the Registry Editor (Open the “Run” dialog box, type regedit and

hit “Enter”).
2. Navigate to the following Registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\
 3. Create a New Key named as StorageDevicePolicies. To do this right-click

on Control, and click on New->Key and name it as StorageDevicePolicies.
4. Now right-click on  StorageDevicePolicies and create a New->DWORD

(32-bit) Value and name it as WriteProtect.

5. Double-click on WriteProtect and set the Value data to 1.
Now the right-protection for USB drives is enabled on your computer (no

restart required) and thus it would not be possible for anyone or any

program to add/delete the contents from your USB flash drive. Any attempt

to copy or download the files onto the USB drive will result in the

following error message being displayed.

To revert and remove the write-protection, all you need to do is just

change the Value data for WriteProtect (Step-5) from 1 back to 0. Now write

access to all the USB devices is re-enabled.
Sometimes it may seem difficult to remember and follow the above mentioned

steps each time you want to enable/disable the write protection. Hence as

an alternative way, there are many tools available to automatically

enable/disable the write-protection feature. One of my favorite tool is USB

Write Protect by Naresh Manadhar. Using this tool you can limit write

access to your USB drives with just a click of a button.

How to Use Windows 7 Without Activation

Windows 7Most of you might be aware of the fact that it is possible to use Windows 7 and Vista for 120 days without activation. This is actually possible using the slmgr -rearm command which will extend the grace period from 30 days to 120 days. However in this post I will show you a small trick using which it is possible to use Windows 7 without activation for approximately an year! Here is a way to do that.
1. Goto “Start Menu -> All Programs -> Accessories” . Right click on “Command Prompt” and select “Run as Administrator“. If you are not the administrator then you are prompted to enter the password, or else you can proceed to step-2.
2. Now type the following command and hit enter
slmgr -rearm
3. You will be prompted to restart the computer. Once restarted the trial period will be once again reset to 30 days. You can use the above command for up to 3 times by which you can extend the trial period to 120 days without activation.
4. Now comes the actual trick by which you can extend the trial period for another 240 days. Open Registry Editor (type regedit in “Run” and hit Enter) and navigate to the following location
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform

5. In right-side pane, change value of SkipRearm to 1.
6. Now you will be able to use the slmgr -rearm command for another 8 times so that you can skip activation process for another 240 days. So you will get 120 + 240 = 360 days of free Windows 7 usage.
120 days using “slmgr -rearm” command before registry edit +                                                                                                                                                                 
240 days using “slmgr -rearm” command after registry edit
 =      360 Days
