How to install and enable telnet in windows 7
Telnet Client is a useful utility that helps us determine whether remote or local network services are running and reachable from the client side. For example, to test for a service running on port 8080 on a remote host you would type telnet remote host IP 8080 from the command line. Then you act according to the command’s reply. Remember that telnet does not provide you with enough information to diagnose all network/service problems; however, it is a very handy tool! Operating systems before Windows Vista had this utility installed by default but now you have to do some extra steps as detailed below:

Filename extensions – Can’t open .exe files?
Every filename has a name and a three-character filename extension with the exception of the latest versions of Microsoft Office products that have four characters. This extension typically defines the type of file. For example, files ending in .doc are Word documents while files ending in .xls are Excel sheets. When you double-click a file that ends with an .exe extension, the system will attempt to execute the file. If you change the extension of an executable file, the file will still contain executable instructions; however, the system will not attempt to execute the file because it does not recognize the filename as an executable file type. To change the associate program of a file you right-click the filename from windows explorer and click the properties menu. The file properties window opens:

Gigabyte X58A-UD3R RAM problems
One of the most tricky hardware problems is the RAM! Problems with RAM vary from speed, capacity, chips, and brand mismatch to seating problems. A newly installed Gigabyte motherboard (X58A-UD3R) running Windows 7 Enterprise edition installed with 6GB of RAM was reporting just 4GB of usable memory. Three modules of 2GB each were installed in the correct channels that is, in the DDR3_1, DDR3_3 and DDR3_5 sockets while all modules were identical. Upon every reseating attempt, the system temporarily reported the correct amount of memory. (Reseating the RAM means with the computer switched off, you uninstall and install back the RAM modules as to verify that they are correctly assembled in their respective sockets)
The Windows Experience Index for your system could not be computed
The Windows Experience Index measures the capability of your computer’s hardware and software configuration and expresses this as a base score. A higher base score generally means that your computer will perform better and faster. I find this utility useful when performing certain tasks that require certain resources. For example, I expect to be disappointed when running graphics-intensive games while my current Gaming graphics sub-score is less than 3.5!
Each component (Processor, RAM, Graphics, Gaming graphics, and Primary hard disk) gets an individual sub-score and the base score is determined by the lowest score. Therefore, the base score is the lowest value amongst the sub-scores! When you upgrade the hardware, you may need to re-run the test as to find whether your new hardware performs better!
