How to restore registry values?

Hello,

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.

Registry disclaimer

To do so: Important this section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these
steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article

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.

 

Change registry value in dynamically created registry key

Hello,

I need find a way to disable the onboard microphone on a number of Windows 10 laptops I am imaging via SCCM OSD. After a lot of research it seems the best way to do this is by changing a registry value that controls whether the mic is enabled or disabled.
I've tried using Devcon to disable the microphone, which after running the command will show the mic as disabled in control panel but it will continue to function. I found going to "sound" in control panel and disabling it from there will do the job but I
need to automate this, hence the registry. The problem I have is the registry key the value for the mic is stored under is randomly generated when the laptop is built.

The key I need to modify is stored at this location:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Capture\<randomGUID>

DeviceState = DWORD

To disable the mic, the data for DeviceState should be set to 10000001 in hex or 268435457 in decimal.

I figure the best way to do this is might be to use powershell to search the registry for the key, assign it to variable, and then have it update the value. The criteria to find the key could be by the following value and data:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Capture\<randomGUID>\Properties

Value: a45c254e-df1c-4efd-8020-67d146a850e0},2 = REG_SZ

Data: Microphone Array

Unfortunately I know very little of powershell outside of running basic commands and do not know how to script this to make it work. Can anyone help me figure this out or if anyone has a better idea how to disable the mic, I'd be happy to listen.

Thanks in advance
