... I accidently deleted my config.sys file for windows 7 ...
Accidentally deleted it from where? Windows 7 uses a Config.nt file for configuration of its
command prompt (e.g. cmd) console window. There is a Config.sys file used for the
NTVDM (e.g. NT Virtual Dos Machine) but that is generally so hidden to the casual user you have to expend no small amount of effort just to find it.
In any event you can recreate either file with Notepad. Click Start or tap the
Windows key and type notepad then hit <enter>. To recreate the default 10 byte
Config.sys file paste this into the new Notepad document,
FILES=40
... then hit <enter> so the cursor is on a new line and Save As a new
Config.sys file in the folder of your choice.
If you need to recreate a new 132 byte Config.nt file, start with
Notepad again and paste this into the new text document,
dos=HIGH,UMB
device=%SystemRoot%\system32\himem.sys
files=250
buffers=50
REM device=%SystemRoot%\system32\drivers\hpscan16.sys
... then hit <enter> so the cursor is on a new line and Save As a new Config.nt file in the %SYSTEMROOT%\System32 (e.g.
c:\Windows\System32) folder. Note that a Config.save is also in the
System32 folder if you need another reference.
