All you need to copy Microsoft Works to a flash drive is a legal copy of Works and a USB flash drive with around 500 MB (depending on your version of Works) free.
You will also need a PC or laptop with a working DVD/CD ROM drive, and 500 MB of hard disk space. The first thing you must do is copy the contents of your Microsoft Works disc to your hard disk.
Begin by creating a folder on your PC into which you will make your copy of the Microsoft Works installation files. You might call this MSWorksTemp.
To proceed, place your Microsoft Works disk into your CD ROM drive. If the autorun installation screen appears, click Cancel, Exit and then Finish. Instead, open My Computer (either on the desktop or via the Start menu.)
Right-click your DVD/CD ROM drive and select Explore. Next, right-click and copy the MSWORKS directory, then browse to MSWorksTemp and go to Edit > Paste. The contents of the disc will copy to your hard disk drive.
