Fix blurry fonts in Delphi 5 IDE on Windows 8

The post can save you a quite amount of time. Following steps helped me (although there are could be other solutions).

1. Open command prompt and run regedit.exe
2. Open folder HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts
3. Find all entries for MS Sans Serif and set them to tahoma.ttf
4. Open folder HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes
5. Find entries MS Shell Dlg and MS Shell Dlg 2 and set them to Tahoma
6. Reboot system
7. Open display settings (Right click on desktop - Personalize - Display). Check that there 100% scaling is set (slider is on Smaller value)
8. Turn ClearType ON and adjust it to your taste
9. Use your monitor settings (if available) and adjust sharpness
10. Reboot system one more time
