# OpenGlass
A replica of the dead software glass8, also known as the upstream project of [DWMBlurGlass](https://github.com/Maplespe/DWMBlurGlass).

This software is designed for Windows 10 2004 to Windows 11 23H2, which is currently in its early stages and may have various efficiency issues and bugs. OpenGlass works with Windows 10 1809 at a minimum, but I highly recommend you to use Windows 10 22H2.

Some simple tests show that at lower blur radius OpenGlass performs slightly worse than glass8, but at higher blur radius the performance will be a bit better. For some applications where `DwmEnableBlurBehind` and `DwmExtendFrameIntoClientArea` are used in combination, OpenGlass performs almost twice as well as glass8.
This branch does not rely on `dcomp` and `Windows.UI.Composition`, so it is very limited in functionality and it is not unusual to encounter all kinds of bugs, but its performance is much better than the master branch. Currently this branch ONLY supports Windows 10 22H2.
> [!IMPORTANT]
> This software is intended for advanced users only. If you are a beginner and you do not have deeper knowledge of Windows (such as registry editing etc.) you should not install this software.
> For the average users, you should consider using [DWMBlurGlass](https://github.com/Maplespe/DWMBlurGlass).

4. When you use it for the first time or just after updating your system, OpenGlass will try to download the symbol files and you will see its download progress bar in the taskbar, but please don't close it and be patient for about 15s. When the symbol files are ready, enjoy!
5. When you want to stop using OpenGlass or update the version of OpenGlass, running `shutdown.bat` will remove the effects of OpenGlass for you and exit the helper process. At this time, you can either replace the OpenGlass files or continue to run `uninstall.bat` and manually delete the remaining files to complete the uninstallation.

## Documentation (Migrate from glass8 to OpenGlass)
The following table demonstrates the similarities and differences between these two software.
> [!NOTE]
> 1. Most of the OpenGlass settings are stored in the `HKCU\SOFTWARE\Microsoft\Windows\DWM` and `HKLM\SOFTWARE\Microsoft\Windows\DWM`, but some registry items are stored only in HKLM and will remain constant at runtime.
> 2. All external resources referenced by OpenGlass must ensure that it can be accessed by DWM, so paths like `C:\Users\*` are invalid.
> 3. Normally, OpenGlass uses the udwm internal API to get the calculated color instead of reading the registry directly to get the color.
## Documentation
The legacy branch can use most of the features of the master branch. The following table lists the difference with master branch. The legacy branch uses the colors stored by `CTopLevelWindow`, so you can change the color settings using AWM without problems.

- `Not implemented` means that this feature has not yet been implemented but is possible in the future.
- `Not supported` means that this feature is impossible to be implemented in current structure.
