Windows users do not have a lot of options when it comes to text rendering. Basically the only option available for them is to enable ClearType, a technology developed by Microsoft that improves the readability of text on Liquid Crystal Displays (LCDs).

the Gdipp project has been designed as a replacement of the standard Windows text renderer to bring text rendering in Windows closer to how text is rendered in Mac OS and Linux distributions.

Take a look at the two screenshots below to see the difference in text rendering quality.

Gdipp text rendering is offered as a 32-bit and 64-bit version most suitable for installation on computers running Windows 7 or Windows Vista. The developers say that it might also run on Windows 2003 and Windows XP but state that the default installation mode might cause system stability problems.

Gdipp can be installed in three different modes. It can be installed a s service which is the recommended mode combining the best compatibility with system wide rendering. The Registry mode is not as stable but provides the best text rendering while the program mode will only switch the text renderer for programs that are dropped onto the program shortcut.

Users will notice that text flickers after it is loaded into applications like notepad or Word which is something the developer's should work on.

The gdipp project is the relaunch of the suspended gdi++.dll project with the following superior features:

* Seamless support for 32/64-bit Windows. The main reason that gdi++ does support 64-bit Windows is the Detours hooking library, which is free only for its 32-bit version. gdimm instead uses the open-source EasyHook library, and support 64-bit Windows from scratch.
* DirectWrite support.
* Vertical text in programs like PowerPoint are correctly rendered. There is no color glitch in PowerPoint presentation.
* Subtitles in various media players (SPlayer,KMPlayer,PotPlayer ...) are rendered without problem, no matter which video renderer is selected. On the contrary, subtitles are displayed only with the Overlay Mixer in gdi++ case.
* Aero window title can be rendered correctly (by default rendered with ClearTyep).
* No glitch after changing the wallpaper in Windows 7 when Aero is enabled.
* Rotated text are displayed correctly.
* Numerous compatibility enhancement (e.g. the control character in the Date/Time window in Windows 7).
* So on and so forth...

Windows users who want to test the text rendering capabilities of Gdipp can download the 32-bit or 64-bit client from the Google Code project website. The website contains several additional comparison screenshots and detailed documentation of advanced features and configuration options.

    An even quicker way to open Task Manager is by pressing Ctrl+Shift+Esc.

    Win+Pause used to be the goto shortcut for me since… W95… Ms recently hijacked it and you now get Sysinfo. Device manager is still accessible this way: the second to last link at the bottom.
