Windows 10: RegSetValueExW failed to write value name and value data to registry

RegSetValueExW Unicode version of function failed to write the value name and value data to registry in windows 10.

The value name contains more than 1000 characters,value data contains 16,000 characters. RegSetValueExW function return returns ERROR_SUCCESS but the value name and value data not written to registry.


If the value name contains less than 1000 characters then the value name and value data are written to registry properly.


Facing issue when registry value name has more than 1000 characters. As per Microsoft Unicode version of value name allowed 16,383 characters. But RegSetValueExW failed to write if value has more than 1000 characters.


Thanks in advance.

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

Plugging values into the registry often has no effect until the user logs off, then on again. Furthermore, the keys and values you mention differ from machine to machine. On my installation they look quite different.

I suggest you have a look at nircmd.exe (or nircmdc.exe). It might do what you want without any coding effort. If this fails then I'm prepared to write a script for you according to your precise specs, but only after you have done some manual tests on several
different PCs.

 

missig registry values

Hi Alistor, if it is empty,

Right click an empty space on the right hand side

Choose New - DWORD (32bit) Value

Name it (Default)

Then double click that value

Set Value Data to “%1” %*

Hopefully after a reboot, that will do it for you . . .
