Restore Windows With Restore Points

In Windows there is a tool called "System Restore" and it can be a very valuable asset when having a problem such as driver or registry problems. Even sound and other system settings/options are fixed.

How does it work

Windows automatically creates restore points (before each installed program or driver) which can be later used to restore your system files and settings to that point in time. Your personal files (photos, documents, emails) will not be affected. Restore points can also be created manually.

You can also undo the changes done by system restore. Useful if it didn't fix the problem.

How To Use Multiple Monitors

How does it work

You can display the same picture in all the monitors, but usually multiple monitors are used as extended displays, making the desktop larger.

All the programs and windows act the same way as normally, you can drag them from one display to another or extend the size of your window over by multiple displays at the same time.

It can save a lot of time in long-term. If you have a lot of code to cover and change it often, testing it is very recommended.

How To Google Effectively

Do you know how to use google search to get the best out of it?

Most people just type in words related to what they're looking for, but that might not give the result they were hoping for.

How to save RAM from unwanted software

RAM ( random access memory ) is used by all of the programs that you run on your computer. Everything that a program loads up is stored in random access memory ( pictures, text, programming language data ). Nowadays, 4 GB or RAM is a very recommended minimum when buying a new computer, but older ones still have 1 or 2 gigabytes of it ( mostly win xp or vista ). Windows 7 eats more ram than vista and xp. I personally have 7 professional ( 64-bit )  and it takes about 1,3 GB-s.

Because the operating system already eats a lot of RAM, we dont want other unnecessary programs to waste it, do we?
