The default operating system for this machine is Windows 7 Home Premium and we are happy to report that Dell installs the 64-bit variant as standard. We get a performance rating score of 5.1 with the default configuration and shown above is the software installed by Dell at their factory. Some of the software is useful, such as Flash and Adobe Reader but there are some useless items such as Live! Cam Avatar Creator. McAfee is also installed but our first recommendation would be to remove this intrusive resource hog and replace it with something like Avast! or Microsofts own antivirus.
Dell also installs their own tweaks on the OS such as a dock which is no doubt designed to appeal to Mac OS fans. There are no lock status LEDs on the Inspiron 15R, Dell software provides onscreen notifications of items such as CAPS LOCK.
Inspiron 15R BIOS
For the Inspiron 15R BIOS Dell use Phoenix based code and like many mainstream machines there are no performance options to tweak. What we can do is enable and disable various devices. For those who want to disable Turbo Mode this can be done via the SpeedStep option.
