In VS 2015 and earlier, settings were stored in the registry, e.g. HKEY_CURRENT_USER\SOFTWARE\Microsoft\VisualStudio\14.0_Config. In VS 2017, to support multiple instances of VS, the settings were moved out of the registry, according to this post.

I have previously been editing the registry to force Dark Theme when Windows is in High Contrast mode, according to this SO answer. Now I want to do the same in VS 2017 but cannot find where the settings are stored, to make this change.

Where are these settings stored for Visual Studio 2017?

I found the answer in this blog post:

See how empty is the regular HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\15.0 key on my machine and notice that there is no 15.0_Config key:

Regedit

Instead, the VS 2017 private registry is stored in your AppData folder:

AppData

Fortunately, you can use regedit.exe to load a private hive. You need to select the HKEY_USERS node, and click the File > Load Hive… menu. You select the privateregistry.bin file, give a name to the hive (I entered “VS2017PrivateRegistry”) and now you can see the 15.0_Config key populated as usual (note: use File > Unload Hive when done):

Private registry

Using this guide, I was able to load the private registry, do the changes from the SO answer mentioned earlier, unload the hive and start VS 2017 with the Dark Theme!

EDIT: I had to slightly modify the PowerShell script I used to edit the registry, here is the updated version if anyone is interested:

EDIT2: Now modified to include the loading of the private registry automatically as well, including a garbace collection to allow unloading the hive:

NOTE: You have to find your own correct path for the user name (C:\Users\Geir) and VS version (15.0_8165452c).

New-PSDrive HKU Registry HKEY_USERS

reg load 'HKU\VS2017PrivateRegistry\' "C:\Users\Geir\AppData\Local\Microsoft\VisualStudio\15.0_8165452c\privateregistry.bin"

$HighConstrastTheme = "HKU:\VS2017PrivateRegistry\Software\Microsoft\VisualStudio\15.0_8165452c_Config\Themes\{a5c004b4-2d4b-494e-bf01-45fc492522c7}"
$DarkTheme = "HKU:\VS2017PrivateRegistry\Software\Microsoft\VisualStudio\15.0_8165452c_Config\Themes\{1ded0138-47ce-435e-84ef-9ec1f439b749}"

Remove-Item -Path $HighConstrastTheme -Recurse
Copy-Item -Path $DarkTheme -Destination $HighConstrastTheme -Recurse

[gc]::collect()

reg unload 'HKU\VS2017PrivateRegistry'

  • Hi there. Thank you for your powershell script. Only the file paths and registry path do not seem to work in all cases. I use the release version of Visual Studio 2017 and the path of the private registry and the path of theme settings in the registry. In order to make this work I had to change the script like this: – Jacob de Boer Mar 15 '17 at 09:00

    @jacobdeboer Yes, the paths might be slightly different for your case. I will add a note about this. – Geir Sagberg Mar 15 '17 at 09:02
  • Is loading these hives and editing them programmatically possible? The C# Win32 registry class does not appear to support this unless I am mistaken? – Shiv May 05 '17 at 05:06
  • Remember to unload the hive otherwise VS won't start – ccalboni Sep 22 '17 at 08:12
  • A bit of a hassle,. wondering why they can't just add "search result format" to the regular settings.? anyhow - https://blogs.msdn.microsoft.com/zainnab/2010/01/03/customize-how-find-in-files-results-are-displayed-in-the-find-results-window/ : explains what each setting does for the search results format. – T.S Nov 22 '17 at 10:25

I've implemented a batch-file-based approach that does everything automatically and also backs up the high contrast theme in case you need to restore it for any reason.

You can find it at https://randomshaper.blogspot.com.es/2017/06/visual-studio-2017-high-contrast-hack.html

The following VS2017PrivateRegistry.cmd batch file loads registry keys for all Visual Studio 2017 instances as HKLM_TMPVS_[id], starts Registry Editor for you to make changes in Visual Studio settings and unloads keys when you close Registry Editor:

for /d %%f in (%LOCALAPPDATA%\Microsoft\VisualStudio\15.0_*) do reg load HKLM\_TMPVS_%%~nxf "%%f\privateregistry.bin"
regedit
for /d %%f in (%LOCALAPPDATA%\Microsoft\VisualStudio\15.0_*) do reg unload HKLM\_TMPVS_%%~nxf

Note: first close running Visual Studio 2017 instances with background processes and then run this file with administrator rights.

See Changing Visual Studio 2017 private registry settings for more details.

By checking the log from Process Monitor you can see it check the same registry key.

VS registry key access

It's just not created. You need to create it. The part of the name (e3d5273c) might be different on your machine.

  • Interesting, not sure why it's looking there as well as in its private registries (see my answer). I won't be pursuing this further as I have found a solution though. – Geir Sagberg Dec 13 '16 at 13:47

The real fix for this would be for the Visual Studio team to allow developers to set the theme. If you are interested in getting this fixed go to this VS issue report and follow it and make a comment supporting it. It is currently under consideration.

Visual Studio forces the user to use its High Contrast theme when Windows is in High Contrast mode
