当你从Windows Vista RTM或Windows Vista SP1下安装Service Pack 2时，如果没有加上参数来安装的话，默认都是会在系统中驻留缓存文件用于回滚。只要无意卸载SP2，我们可以删除这些缓存文件来为磁盘节省出不少空间。

单击“开始”菜单，输入CMD运行命令提示符，在命令提示符下输入：

compcln

如下图所示：

按下Y之后即可自动清理SP2安装缓存文件，删除完成之后大约可以节省300M的系统空间。

Windows 7 RC已经释放了些许天了，随之而来的是Windows XP Mode的公布，什么是Windows XP Mode，Windows XP Mode就是可以让Windows 7能够以Windows XP模式下运行那些本身是为Windows XP设计的应用程序，而恰好这些应用程序不能够在Windows 7下很好的运作，那么Windows XP Mode就是为这种应用程序而设计。下面就是Windows XP Mode的效果图（从sufan那边借过来）：

其实Windows XP Mode就是专为Windows 7特别定制的Windows Virtual PC+Windows XP虚拟机（微软将送一个Windows XP OEM授权），那Windows XP Mode和Microsoft Virtual PC 2007有何区别呢，从下图对比中可以看出来：

可以从上图中看到，Windows XP Mode就是Windows Virtual PC的子产品，可以说就是Windows Virtual PC加送一个合法授权的Windows XP虚拟机。

本文要介绍的另外一个主角是已被Sun公司收购的VirtualBox这款开源免费的虚拟机软件，从上图中我们可以看到Windows Virtual PC支持集成模式，这个模式可以在运行虚拟机时，应用程序窗口和宿机操作系统应用程序窗口混合而看不出来是虚拟机，VirtualBox也支持这个功能，这个功能叫做“无缝模式”，并且VirtualBox还支持运行Linux、FreeBSD等操作系统平台作为虚拟机。Windows Virtual PC支持USB，VirtualBox也支持USB。Windows Virtual PC要求必须是支持CPU硬件级虚拟化技术的平台才可以运行，VirtualBox也支持CPU硬件级虚拟化技术但不强制要求。看似VirtualBox在这些方面都要超过Windows Virtual PC，但Windows Virtual PC强就强在是微软自家推出的，其集成模式会非常稳定，而VirtualBox虽然有“无缝模式”，但运行不是很稳定，比如我在Windows Vista SP1下运行最新版VirtualBox+Ubuntu，使用“无缝模式”无法看到Ubuntu。

VirtualBox对于Windows Virtual PC一个很大的优势应该就是给那些在用Vista的用户一个可以运行“Windows XP Mode”的机会，毕竟微软现在没有明确说明是否会提供给Windows Vista用户使用Windows Virtual PC，而作为Windows 7的一大卖点，应该不会轻易提供给Windows Vista用户。不想升级到Windows 7的Windows Vista用户也有机会体验Windows XP Mode，用VirtualBox吧。

和Windows Vista一样，Windows 7也有升级顾问(Windows 7 Upgrade Advisor),Windows 7升级顾问会检测当前计算机的硬件和已安装的软件是否兼容支持Windows 7的运行。

Windows 7升级顾问可以帮助你了解你的计算机迎接是否适合运行Windows 7，当前的操作系统是否可以升级至Windows 7。当前Windows 7升级顾问还在Beta阶段，结果仅供参考。

一般情况下Windows Vista可以升级至Windows 7（自RC版本以后），而Windows XP则需要格式化全新安装Windows 7了。

Windows 7升级顾问支持在以下系统中运行：
Windows XP SP2 or later,Windows Vista,Windows 7（如果我都运行Windows 7了，还要这个升级顾问干啥……）。

在Windows XP SP2 or later上需要.NET 2.0支持

在Vista的UAC控制下，对于那些没有用到自动提权API的应用程序，如果我们要给这类程序提权就需要右键这个程序的可执行文件或者快捷方式选择“以管理员身份运行”来提权，如果我们需要常常运行那些需要手动提权的应用程序，我们可以给这个程序设置程序兼容性之特权等级：

右键选择需要操作的应用程序，选择“属性”，在“兼容性”标签卡下的“特权等级”可以勾选“请以管理员身份运行该程序”的复选框：

这就可以在日后直接双击这个应用程序便会以管理员身份来运行这个应用程序了的，但是如果将所设置的应用程序的文件移动一下位置就会发现先前的设置无效了，先前设置的“请以管理员身份运行该程序”的复选框也被取消了。这就说明Vista系统对应用程序的程序兼容性设置不是修改了应用程序本身，而是将设置记录存储在某个数据库或配置文件中的。根据观察研究进一步确定了这个设置是存储在注册表某个注册表项中的，这个注册表项位置是：

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers

在这个注册表项下被设置的应用程序会在这里建立一个该应用程序的完整路径的字符串值（REG_SZ），数值内容是“RUNASADMIN”，所以当这个被设置的应用程序移动到别处，这个注册表项里的记录没有被更新，所以移动位置后的应用程序的程序兼容性下的特权等级便是没有被设置的。

关于应用程序的程序兼容性的设置也是存储在上述注册表项的上级注册表项：

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Compatibility Assistant

Vista的UAC虽然在一定程度上带来些许麻烦，但是更多带来的是安全上的增强，请不要关闭UAC来换取那一点点方便却带来更多安全隐患。

[Vista非主流]是我的关于Vista的基本使用方法、技巧、故障解决等文章的专题集合，之所以叫做非主流，和Vista与老产品XP的市占率相比较而得出的结论，Vista还是非主流产品。
