Getting the BIOS version for a Windows XP PC is easy using the Registry Editor. You will need to start up the Registry Editor and then drill down into the Registry to locate your BIOS version.
- Start Windows Registry:Click the Windows Start button followed by Run. Type in “regedit” and click the OK button. This will launch the Windows Registry Editor.
- Drill Down to System: Now use the tree menu to expand the following items – HKEY_LOCAL_MACHINE >> HARDWARE >> System. Highlight System which will provide system hardware information.
**Windows 7 NOTE** On a Windows 7 64-Bit computer the regedit tree should be expanded to HKEY_LOCAL_MACHINE >> HARDWARE >> DESCRIPTION >> System. I assume this is the same for all versions of Windows 7.
- Read System Variable:There will be variables/settings in the right window once you have highlighted System in the tree menu. One of these items is SystemBiosVersion which will provide the details of your BIOS. Currently my BIOS reads as shown below in the image.
As you can see in the image above my current BIOS version is 1.10 A07 on a Dell computer. You should always check to see if a BIOS upgrade has been released by your PC manufacturer such as Dell or HP. Upgrading the BIOS can resolve issues with your computer.
