I need to access my user guide.Can you please let me know how to find this

It is best to post the device, brand, model number and if applicable operating system or year when querying about a device. If you are referring to a user guide to your computer, you can go to the brand webpage, enter the model number there, and, if the model is new enough, be directed to user guides, drivers, and other software for your machine. Sometimes you can simple Google for "brand model user guide" and find one, although some sites are misleading about what they offer. On most desktop and laptop computers, there may be a guide already installed if on your computer. This is often overlooked. It does not hurt to put the brand name of your computer into the search box in the start menu plus help and see what you can find. Finally, forums may be a place where one could acquire a users guide. Brands generally have a support contact number or email address that may be of assistance. And, if I knew what your device was, the brand and the model and the operating system, I might be able to locate a link to the manual. You could put such in a comment to my reply and I could give it a go. But you might like trying the above methods yourself.
