Windows XP Home Edition (also known as Windows Server 2021) comes with the Microsoft Application Service that includes the Microsoft Caffeine. Caffeine is a utility for the Windows operating system. Caffeine is a sidekick of Microsoft Works. Caffeine is not a program per se; rather, it is a tool for analyzing work performance and saving the results in a file.
Caffeine can be downloaded for free from Microsoft Works or you can also obtain a free trial version of the software. With a free trial, you are able to test the application to see if it will work for your purposes before purchasing the full version. On average, Caffeine downloads just under two megabytes of data. In most cases, this is not enough space to install other programs. All in all, Caffeine is a very useful application which is able to save time when performing multiple tasks.
Once you download Caffeine, you should launch it by clicking on Start, then Run. Then type "caffeine" into the field given on the Control Panel window to open the software file. When Caffeine is running on your Windows XP computer, you can monitor how much time it is using up your computer's resources - how many times it starts or stops in the foreground, processes that are taking up system memory, total memory taken up by your operating system, and so forth. You can also see the current rate of CPU use by the operating system.
