UxTheme Signature Bypass

UxTheme service hook - Visual Theme Signature Bypass

Something to know?
Yes! There is one very important thing if you use Aero Glass for Win8.1! Due to certain DbgHelp.dll restriction, Aero Glass for Win8.1 won't able to load PDB symbols after you install UxThemeSignatureBypass.dll into your system. There is a simple workaround - just copy symsrv.dll from Aero Glass directory into your system directory (probably C:\Windows\System32). I will try to bring a fix for this in future version of Aero Glass for Win8.1, but I cannot promise that, because its a bit complicated.

Hi Big Muscle, does the UxThemeSignatureBypass DLL set and the 1.3.1 or beta 1.3.2 Aero Glass combo still have the above listed limitation? And if so, can symsrv.dll be in another place in the path or is it required to be in System32?

Thanks.

I would like to use UxThemeSignatureBypass to run custom themes but I do not want to use Aeroglass.

Can someone give me some help in the installation of UxThemeSignatureBypass without having Aeroglass involved?

Thanks in advance, Undine.

**bigmuscle** · November 17, 2015

This is separate library and you don't need Aero Glass for it.

Maybe it should be good to read the first post of this topic ;-)

I have read the whole thread several times but unsure about some things. Some people show changing several things in the registry. Some talk about a boot setting change.

How to install?
The only possible way to install it is using old injection method via AppInit_DLLs registry key.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows -> set AppInit_DLLs value to specific DLL for your OS (so select either xxx32.dll or xxx64.dll only!)

If I put UxThemeSignatureBypass64.dll into a folder at C:\UxThemeSignatureBypass64 and then change

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows -> set AppInit_DLLs value to.....C:\UxThemeSignatureBypass64

is this all that needs to be done?

Thanks for your help. undine

you contradict yourself - if you put it in a folder in C; then you would have to add the folder name into the string - if you put it on the face of C: then your string should work - however if you are running the new release of 10 there is little point as 3rd party themes dont seem to work

**undine** · November 18, 2015

OK, I see where I did not add the dll in the C: address. Thanks again. undine

UxTheme Signature Bypass doesn't seem to work on Windows 10 x64 Th2 10586.14. I use this setting

"LoadAppInit_DLLs"=dword:00000001
"RequireSignedAppInit_DLLs"=dword:00000000

"AppInit_DLLs"="C:\\AeroGlass\\ModernFrame.dll,C:\\AeroGlass\\UxThemeSignatureBypass32.dll"

I have the 2 UXThemeSignatureBypass dll files in C:\AeroGlass folder. When I apply any themes nothing happens.

It sort of works, it does still bypass the theme signature but it wont let you apply custom themes in the personalization menu, it will still let you test themes using Windows Style Builder, the only current method that's working is to use patched theme files from 10240 but only themes made for TH2 10586 will work, if you try using an old theme you will end up with a flashing black and grey screen.

If BM can find out why it doesn't let you apply them in the personalization menu now it would be great as I hate having to use patched theme files from 10240.

I think MS might have made this intentional, not as a FU or anything, but I think they knew that people were using custom themes and Windows 8 themes and that if they didn't somehow disable the use of custom themes then there would be many people with bricked systems after the TH2 update, that's still not a great reason for it though because the changes in the msstyles that broke backwards compatibility seem so minor and I think they could have been much better implemented.

Tbh the msstyles is becoming a complete joke, there are so many left over parts in it dating all the way back to Vista, there are still parts from the Vista start menu and taskbar as well as random parts from the Windows 7 start menu and many random left overs from Windows 8, there is also now 3 different right click context menus.

Yes, as a FU to their customers. They need to change the culture in order to take fleecing to the next level. This involves ruining every current expectation, so that people are happy to pay for excrement.

**CKyHC** · May 17, 2016

I don't understand - how to apply custom theme with UxThemeSignatureBypass in Windows 10586.318.

In 8.1. all works fine. In W10 all registry values the same. Try to apply theme for W10 10586 from http://sagorpirbd.deviantart.com/art/Aero-7-Themes-for-Win10-Final-523979941

Nothing happens from Personalisation. Please help. I don't want to use UxStyle, i like UxThemeSignatureBypass.

**MTDirector** · May 17, 2016

In Windows 10 TH2 MS have "blocked" customs theme normal installation. To use them, go into %systemroot%\Resources\Themes\Aero and rename aerolite.msstyles into aerolite.mssstyles.bak
Then, create a folder named aerolite.msstyles at the same place and put all your customs theme into it.
Go back to the Themes folder and change in your .theme file the line %windir%\Resources\Themes\MyTheme\MyTheme.msstyles by %windir%\Resources\Themes\Aero\aerolite.msstyles\MyTheme\MyTheme.msstyles where MyTheme is the name of the custom theme.

That's all, normally the custom theme should apply
