Try this:
Paste the following code in Notepad and save it as anyname.reg file (not .txt) and run it to add the information into the registry:
Code:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes]
"MS Shell Dlg 2"="Tahoma"
"MS Shell Dlg"="Tahoma"
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]
"NoSaveSettings"=dword:00000000
---OR---
You can also do it manually with Registry Editor. I think your default XP font is set to
"System". Just make it
"Tahoma" at the given location in the code written above.
After doing these changes restart your PC...
