Symptoms
Applications which use the bitmap fonts Courier, MS Sans Serif and MS Serif may be effected if the system is set to 120 DPI during Windows 7 setup.
If the DPI is then changed back to the default (96 DPI), the applications using bitmap fonts Courier, MS Sans Serif and MS Serif will still render the text as 120 DPI.
Cause
Windows 7 automatically detects High DPI support during setup and sets the system to use 120 DPI. This consequently changes the bitmap fonts Courier, MS Sans Serif and MS Serif to the ones below to support 120 DPI.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts
COURF.FON
SERIFF.FON
SSERIFF.FON
In Windows 7, DPI is a per user setting. When the user changes the system to 96 DPI, the bitmap font does not get updated to the correct ones which support lower DPI. The fonts that support lower DPI are:
COURE.FON
SERIFE.FON
SSERIFE.FON
Note : This font mapping is for codepage 1252
