How To Block Failed Login Attempts In Windows 7


Even if you put a password on your computer, that doesn’t stop someone from breaking in by using a brute force password guessing technique.  Although more of a problem for Laptops than your home desktop, I’m going to show you a trick used by almost all corporations who run Windows.  Essentially what were going to do is run a command that will lock your login account for a specified amount of time after a specified number of bad login attempts (wrong password).  By doing this an attacker won’t be able to use an application to try a few million passwords per minute against your computer to break in since every 10, 20, 30 etc. attempts will lock the account for a few minutes thus killing any attempt to break in.  Here, let me show ya.



Step 1 – Launch CMD as an administrator
Click the Start Menu Orb and Type cmd into the search box.  Under the programs list that appearsRight-Click cmd.exe and Select Run as administrator from the context menu.

Step 2

In the command line, Type in the following command:
net accounts /lockoutthreshold:10
You can replace the number 10 with any number you like, this will determine how many incorrect password attempts can occur before a lockout is initiated.  Personally, 20 or even 30 should be fine but 10 is a good number for most people even if you commonly fat finger your password….



Step 3 – Set the account lockout duration

By default, when your account is locked due to the X failed attempts you set above, your account will be locked out for 30 minutes.   I personally think that’s a bit excessive.  My recommendation is you change it to something like 3 or 5 minutes so even if you fat finger your password, you only need to wait a few minutes to try your password again.  You can change this using the following command:
net accounts /lockoutduration:30
The lockout duration can be set to any value between 1 and 99,999 minutes.*  If you set it to 0, the account will be locked until an Admin unlocks it… Don’t do that.
*This range varies depending upon which version of Windows 7 you are running.




Done!

Now whenever someone attempts to break into your computer by guessing your password Windows will lock them out!

How to block access to certain drives in Windows 7 ultimate/premium


I usually store all my important files and documents in one separate drive on my laptop and I always wish that no one else could touch them without my permission. And when I give my laptop to other people I always fear that the person using my lappy might access my personal files. If your computer is accessed by many people then you may want to restrict access to certain drives on your computer for other users.
To block access to drive go to Computer and right click on the drive and select properties. In the properties window click on ‘Security’ tab. Select the user account you want to restrict and click on edit.

Change the permissions according to your need for user groups or a particular user and click Apply and then OK.  It will not work for users with admin account as even they have the same rights as you so they can revert all permissions. You will need an admin account to perform this task.This trick is for Windows 7 ultimate and premium edition users.

Slide helper as the name suggests is an application which lets you modify the functions associated with the slider. With this application you can do more with the slider than just answering calls or writing messages. This application is supported by symbian OS phones specially the symbian S60 third edition phones which are j2me enabled.
clip_image001The key features of slide helper include:

Moreover there is very little support available for this slide helper and getting the valid certificate is not an easy task as far as slide helper is concerned but the easiest way that I can recommend is to crack your phone, by doing so you bypass the certificate check and the applicationworks correctly.
