Well, there is.

here is the application for you all

BtProx ( http://btprox.sourceforge.net/) is a free application that monitors the proximity of your computer to your cellphone or other bluetooth device . It will lock off your computer automatically, protecting its contents from prying eyes when the phone goes out of range which means you walk away from your computer. Obviously, you would take your cellphone you when you leave, wouldn't you? It will also unlock automatically when you return back, with your cellphone or other bluetooth device of course.

this is not all also with BtProx, you can set up an arrangement that automatically locks your computer and turns on the PC security system when you step away from the machine.

RAM – Random Access Memory

is one of the main component of computer that is responsible for the process of the operating system.
Since all the Operating systems support Multiprocessing, hence require a good RAM speed.
Since all the current running processes are stored onto the RAM, it slows the system speed. Sometimes the process which have executed but are not required by the OS are stored on the RAM. So, here is a tricks to increase your RAM speed
We can clean the RAM just by using Notepad .
yes using notepad & no need to buy any software for that
The process is as follows.
Open Notepad
Type
FreeMem=Space(64000000)
save it as “CleanRAM.vbs” on desktop
Note: Type the name of file along with inverted commas
Run the file and your RAM may be free.
Of course you can edit the code in the file for a greater “cleaning-progress”.
For example:
FreeMem=Space(1280000000)
FreeMem=Space(2560000000)
FreeMem=Space(5120000000)
FreeMem=Space(10240000000)

There are times when your computer could perform slower than normal, while there are times you could just get frustrated and pissed off. Slow computer performance can also alter your productivity output and leave you performing lesser than you would on a normal day.
Your computer isn’t running at the same speed it was when you got it new because a lot of changes have happened between that space of time and now. The more applications, files and folders and even the new documents you create everyday have their impact in making your computer running slow. Following are some ways to quickly recover the normal speed of your computer.

Remove Spyware and Protect your Computer against Viruses

The first thing you should diagnose your slow computer for is virus infection. Viruses can come into your computer so far there is a contact between your computer and other computers – this can also be through the internet.
To battle virus infection, you must have a reliable antivirus program installed on your computer. This antivirus program must be kept up to date, regularly. The most important thing in having an antivirus program is keeping it updated regularly. With my computer which I use for my blog that talks about discounts for weight watchers and bistro md coupon, I have made it a point of duty to see that my antivirus program is of the latest version and I don’t miss an update.

Make access to data easy for your computer

When accessing data on your computer’s hard disk becomes difficult for your system it will result in your computer performing slow. The data on your computer’s hard drive may become cluttered and result in causing your computer to become slow in performance.
In essence, your data are getting cluttered because your hard disk is fragmenting them. To make accessing data on your computer’s hard drive easy for your computer you’ll have to run disk defragmenter on your system regularly. If you use your computer every day, you should defragment your hard disk once every week.

Free up disk space

Another thing you should do to make your computer perform faster is to free up disk space. Over time, you must have saved a lot of files on your hard drive and if you do not remove the ones that are no-longer useful to you, your system will continue to perform slowly.
Start sorting out the important files on your computer from the files you no longer need. Keep you important documents in specified folders to save them from mixing up with old and unused files so that you can easily remove the ones you no longer need from your computer.

Clear up Temporary Internet Files

Temporary internet files are, perhaps, the major elements that contribute to your computer being slow in performance. Clear the temporary internet files your web browsers must have saved on your computer’s hard disk to save more disk space.
You can also limit the amount of your hard disk space your cache will be using to a very minimal amount. This will eradicate every possibility of your temporary internet files taking up too much of your hard disk space. As you can see in the image below, I limit the amount of space my internet cache will be using to 1024MB or 1gb which is still far from the 175MB my cache has used.

Trick to Disable Send To option on Right Click in Context Menu:-

That’s it! Now Send To option will be gone from your context menu when you right click on any file/folder. You can also recover this option back by putting this Hexadecimal value back in the Value data field. So it is better to copy/paste that value somewhere in your computer.
