Windows 10: Registry key for BIOS Mode value in System Summary?

Looking at System Information there is a value "BIOS Mode" under System Summary which will be either UEFI or Legacy. What is the key in the Registry that holds this information?


Thanks in advance for any assistance!

ForcedReboot Registry Key Value

Hi Daniel,

ForcedReboot is one of the subkeys in the registry. Subkeys contain data entries called values. The presence of a value on a key is a form of data that an application requires for it to run. An application opens a key and uses the values associated with
the key to perform specific functions. A key can have any number of values, and the values can be in any form.

You can visit these links for further information about registry values:

• Registry Value Types.
• Registry Element Size Limits.

Note: We do not recommend navigating and editing the values of the keys and subkeys in the registry. Changing the values of the keys and subkeys in the registry might cause serious system issues.

We would like to ask if you are experiencing any issues on your Windows device. Since you are interested on finding what the value of a subkey stands for, we think that you are trying to troubleshoot your computer. If in case you are having any errors or
issues with your Microsoft products, let us know so that we could assist you further.

We are looking forward to your response.

 

How to restore registry values?

Thank you for posting your query on Microsoft Community.

You can perform system restore and check if it helps:

Perform System restore.

I suggest you to perform system restore and select a date prior to the changes which was done with the registry values and check if the issue gets fixed.

To perform System restore:

• Press Windows key + X, select
  System.
• In the left pane, click on System Protection.
• Select the option to system restore
  > next. It will show all restore points already created.
• Select the date prior to the date on which you have made the registry changes.

ForcedReboot Registry Key Value

We appreciate that you provided a clarification on your concern. Upon researching on this, we identified that the number on the Value stands for how the subkey behaves. If the Value is 0, it means that the subkey is disabled. And if the Value is not 0, then
it means that the subkey is enabled. You can visit this link for your reference.
