Reduce the size of a wav file

.wav files are usually big in size, and it comes in to problem when you wanted it to use in some interactive systems, like the voice interaction software or IVRs.

today i found a very handy way to reduce the size of the wave file with out using any third party software. windows has a tool called sound recorder ( Programs>accessories>entertainment>Sound Recorder ) or sndrec32.exe ( type it in Run window )

To reduce the file size or change the attribute of your .WAV file, you can go to file>properties> and click to the convert now button. this will open up a new window

from there you can select the target format, there are a variety of target formats which allows you to convert your WAV files in to 1/10th of the actual size.

Choose your desired format by looking the KBs/second( which is displayed at the right side of each entry).

NetGear wireless issue - windows cannot find wireless network

One of my laptops are pretty old and having no built in wireless Lan, so i bought one USB NetGear wireless lan adaptor, and when installed it in my laptop.

then i experienced a problem like the netgear utility is not smart enough to enumerate all the wireless networks nearby. and it sounds not good for me. and it denies the windows to enumerate wireless networks. ( windows network finder is easy and hassle free, so i prefer that)

How can we enable windows to enable the wireless networks ?

Enable the windows service named Wireless Zero Configuration, go to control panel>Administrative Tools>Services and find Wireless Zero configuration service, and start it.

or Run services.msc to reach in to services in an easier way!
