Back Up Your Files!	This is something that everybody should do but people frequently don't. Possibly the main reason is that either they don't want to spend the money on a commercial backup solution, or they don't know how to use the one they have. Backing up by hand is just too time consuming. It is fairly easy to create a batch file that will copy the contents of one folder to another and then use Windows 98/ME scheduling to run that batch file on a regular basis. Fairly easy to do and very inexpensive.
If a program crashes restart your computer.	Most of us have received an error message something like, "The program has performed an illegal operation and will close", or have a program freeze and were able to shut the program down from the "Close Program" Window (Ctrl + Alt + Del). It is a good idea to restart your computer when this happens. One of the most frequent causes of problems is when a program tries to use a section of memory that it shouldn't. This can cause other programs (or the operating system) to crash without warning. Restarting your computer will clear any bad data from the memory.
Close many open windows with a single click.	If you like to have each folder you open appear in a new window, you will find times when you have tons of windows to close at one time. Instead of clicking on the close window button for each one (button with an X in it, upper right hand corner of the window), hold down the shift key when you do. This will close all of the open windows that were opened from within the window you are clicking on.
Windows ME users, make use of "System Restore" before loading software!	One of the nice features about Windows ME is something called "System Restore" (Start menu-Programs-Accessories-System Tools). If you are going to add a new software product (especially if it is one you download), go to System Restore and create a restore point before you install. That way if anything goes wrong (short of a complete corruption of Windows) you can easily go back to the way you were before.
