(1)??假設texmf目錄在D:盤根目錄下，刪除pgf相關的所有目錄，執行如下DOS命令

rd /s? D:\texmf\tex\plain\pgf

rd /s? D:\texmf\tex\latex\pgf

rd /s? D:\texmf\tex\generic\pgf

rd /s? D:\texmf\tex\doc\generic\pgf

rd /s? D:\texmf\tex\context\pgf

(2)重建TeX文件名數據庫，執行DOS命令：

texhash

(3)上網下載最新宏包壓縮包

(4)解壓壓縮包，把該包下的tex子目錄拷貝至D:\texmf\ 下，全部覆蓋即可。

在Windows XP?和 ChinaTeX20060918測試通過，如下例
