I'm trying to make a minimal XP installation for low-end machines, and I want to remove anything that could slow the system down.

I've heard many fonts installed slow down the boot process, so I'd like to keep the number of them to a minimum, and I'm seeing a lot of .fon files everywhere.

Is it safe to delete all/some (which?) of the .fon font files? They don't look like they're of much use, but maybe one of them is the terminal font?

They're indeed just bitmap fonts. I'd keep the default cmd window font at least, although I don't know what that is. Deleting the rest should be safe for the most part. – John Chadwick Jan 19 '12 at 23:04
    
@JohnChadwick Problem is, I don't know what that font is. Indeed the only place where I see a bitmap font is in the cmd.exe terminal emulator window. – Camilo Martin Jan 19 '12 at 23:11

here is my minimalist list for XP This was to clean the registry itself, before I put my font stack back in, so I am not totally sure about it. It is english only, and was for limited use of the computer , like I did not use servers and terminals. the ariel narrow is not part of the originals.

Windows Registry Editor Version 5.00

[-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts]
"Fixedsys (Set #6)"="vgafix.fon"
"Roman (All res)"="ROMAN.FON"
"Script (All res)"="SCRIPT.FON"
"Modern (All res)"="MODERN.FON"
"Small Fonts (VGA res)"="SMALLE.FON"
"WST_Engl (All res)"="wst_engl.FON"
"Courier 10,12,15 (VGA res)"="COURE.FON"
"Terminal"="cga40woa.fon"
"Arial (TrueType)"="ARIAL.TTF"
"Arial Bold (TrueType)"="ARIALBD.TTF"
"Arial Narrow (TrueType)"="ARIALN.TTF"
"Courier New (TrueType)"="COUR.TTF"
"Courier New Bold (TrueType)"="COURBD.TTF"
"Times New Roman (TrueType)"="TIMES.TTF"
"Verdana (TrueType)"="verdana.TTF"
"Verdana Bold (TrueType)"="verdanab.TTF"
"Franklin Gothic Medium (TrueType)"="Framd.TTF"
"Tahoma Bold (TrueType)"="tahomabd.TTF"
"MS Sans Serif 8,10,12,14,18,24 (VGA res)"="SSERIFE.FON"
"MS Serif 8,10,12,14,18,24 (VGA res)"="SERIFE.FON"
"Tahoma (TrueType)"="TAHOMA.TTF"
"Microsoft Sans Serif (TrueType)"="MICROSS.TTF"
"MS-DOS CP 437"="dosapp.fon"
"Terminal (US) (Set #6)"="vgaoem.fon"
"System (Set #6)"="vgasys.fon"
"WST_Engl"="wst_engl.fon"

I see all the other .Fon stuff in there that your talking about now. And i cannot be positive that I was seeing them all at that time, being hidden.

Thanks, I'll use this as a reference. – Camilo Martin Jan 19 '12 at 23:41
    
I'm curious, there's a few missing, such as italics, I think you don't miss them, do you? – Camilo Martin Jan 19 '12 at 23:46
    
In XP anything could be bent :-) into italics, or Bolded, so I tossed them and let the programs bend & bold them. Hard to remember, this was done soo long ago. – Psycogeek Jan 19 '12 at 23:50
    
Well, I guess people really don't notice that kind of thing (I think I'd do, since I'm a little pedant with fonts), and this is not for my use anyway. Given a choice, probably normal people prefer a PC that runs fast and looks good from a distance. – Camilo Martin Jan 20 '12 at 0:00

In the end, this is how it looks: i.imgur.com/Gl77i.png (I kept some such as Impact so as not to break the look and feel of naive websites that use that crapfront). – Camilo Martin Jan 20 '12 at 0:08

".fon" files contain bitmap fonts. These fonts were used by earlier DOS-based Windows (Windows 3.1 era). They are included in recent Windows releases for backwards compatibility purposes.

If you aren't using any super-old applications that rely on these fonts, you don't need them. The Windows GUI has not relied on them for many, many years.

With that said, I don't know if it's worth the trouble. TrueType and OpenType fonts take far more RAM to load than bitmap fonts. I'd focus on removing as many .ttf's and .otf's as possible - and those only if your systems are really tight on RAM. – Gabriel Bauman Jan 19 '12 at 23:09
    
Gabe: well, I'm trying to make a setup that works for PCs on the range of 512-768 MB of RAM. Since I'll only have to do this one time, I wanted to know if it can be done safely. – Camilo Martin Jan 19 '12 at 23:17
    
Do you know if the CMD console emulator doesn't need them too? – Camilo Martin Jan 19 '12 at 23:19
    
If you are planning to run console applications in DOS emulation mode, I'd leave them in place. However, cmd.exe does use TTF fonts if bitmap fonts aren't available. – Gabriel Bauman Jan 19 '12 at 23:28
    
The more I think about it, a system with 512MB of RAM can handle a few TTFs in RAM. I think you might be over-optimizing here. – Gabriel Bauman Jan 19 '12 at 23:30

Many of them seem to be useless, but accortding to the last post here post, Windows XP expect these .fon files to be there:

  • SERIFE.FON
  • SSERIFE.FON
  • MODERN.FON
  • COURE.FON
  • ROMAN.FON
  • SCRIPT.FON
  • SMALLE.FON
  • SYMBOLE.FON
