Cleaning your system’s registry

If you want to keep your computer working great, you need to clean the temporary files, uninstall unused programs, keep it up-to-date, keep it virus and malware free and clean the registry.

Typically cleaning the registry should be left to a computer savvy person.  Why?  Registry programs find programs that have been uninstalled and have in essence left parts of it behind.  There are tons of programs out there that will find missing pieces of programs left behind.   Three excellent programs are CCleaner,  MVRegClean and TweakNow RegCleaner.  Here’s the results of each of these programs after a run on an older computer.   It appears MVRegClean is the winner….but reading through the results shows that CCleaner and TweakNow picked up some items MVRegClean may have missed.   While MVRegCleaner is more thorough than the others, much like anti-malware products, you may have to run more than one registry cleaner.   Remember, running a registry cleaner and not verifying the entries could lead to programs not working.  Double check the entries that are being removed and always backup the registry.

Why Virtualization?

Virtualization is gaining momentum with information technology professionals because of the ability to install more than one operating system on an individual host computer.  With hardware becoming less expensive, this type of computing is gaining momentum because of the economy, space and consolidation of resources.  With tighter budgets, this is an ideal way to consolidate servers, save on cost with both hardware and making green computing become a reality.

The global economy is making companies leaner.   Information technology professionals need to be both versatile and have a well rounded accelerated education.  With technology growing faster than any individual can learn,  individual IT personnel will need to learn ‘on-the-fly’ and network with other professionals in order to grow in this industry.

Students and professionals in information technology classes will find that virtualization allows them to learn at an unprecedented pace.  It allows multiple operating systems to be used.  With diverse…

Many laptops and usb wireless devices have the 943xx chipset and drivers are often not written well or are not very good.  Here’s an excellent link to these drivers.   These drivers may say a vendor’s name in the description but this may work.  Always have a backup of your computer.   There is never a guarantee that alternate drivers will work.

Note:   The setup may say no compatible hardware is found.  Manually install the drivers.
