GUID Generator

GUID Generator is a Windows tool that gives you the possibility to produce as many global unique identifiers (GUIDs) as you need, customize settings before doing so, and save the results to file.

GUIDs (also known as UUIDs, universally unique identifiers) are 128-bit integer number used for identifying resources and other kind of information. There are many GUID standards available, some of which are supported by this utility.

It's not necessary to go through installation because you can simply unpack the downloaded archive and double-click the .exe to bring up the main app window of GUID Generator. It has an intuitive layout, where you can explore the numerous GUID formats available and pick a favorite one.

These include registry, hex, uniform resource name and Delphi interface modes. To make things even simpler, each GUID format is accompanied by an example. Regardless of the selected standard, it's possible to configure GUID settings by adding a prefix and suffix, making all letters lowercase, swapping bytes and by specifying the number of GUIDs to generate at the same time.

Also, you can instruct GUID Generator to copy the first, last or all GUIDs automatically. These can be manually copied from the right-click menu as well as saved to plain text documents. The parameters can be reset to default anytime.

Additional preferences are related to the display mode since it's possible to collapse the settings panel, make the panel stay on top of other windows as well as hide the grid lines, selected row indicator and table footer.

The software application created GUIDs quickly in our tests while remaining light on system resources consumption. There were no compatibility issues with Windows 10 in our evaluation. Help documentation with examples (including for the console version) is included.

We expected a simplistic interface with basic options for a GUID creator but GUID Generator exceeded our expectations in both regards. It's also freeware, has no software dependencies, and includes a command-line version for those who prefer the console interface.
