I need to modify an existing parameter on Win 10 registry, so I executed:

reg update [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced] "Hidden"="1"

It did not work, so I did reg /? and I notice the update parameter is not even there.

I checked the other parameter, and it seems like there is none for update. Any suggestion?

You can use the ADD command to overwrite an existing value; if you also add the /f option, the value will be overwritten without asking for confirmation.

Also, your syntax is wrong: you must use /v and /d to specify the value and the data, and you must also use /t to specify the value type.

reg add HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced /v Hidden /t REG_DWORD /d 1 /f

  • Hello, Thanks for your response, it works very well and turns the parameter on the registry to 1, but it does not do what I was thinking it will do. What I wanted to be done was if the checkbox on explorer had been turned on to display the hidden files/Folders it to be turned off by an script at the time of Logon... but I noticed it does not do anything to do with that... Have any idea how that can be done? Regards, Jeff P. – user3076278 May 22 '16 at 22:32

  • That's a completely different question, and should be asked as such. – Massimo May 22 '16 at 23:02
