How to Run Windows XP for Free in Windows 8

Microsoft gave Windows 7 users a way to run older applications via Windows XP Mode. With Windows 8, however, that mode is no longer officially supported, and if you want to run Windows XP in a virtual machine, you need the license for it. Lifehacker reader Miloš, however, has found a workaround.

He discovered that within the free WindowsXPMode_en-us.exe file, there's a VirtualXPVHD file containing the Windows XP virtual machine, which you can open in VirtualBox. Here are the steps to get this working:

1. Download WindowsXPMode_en-us.exe from Microsoft. You'll need to run the validation tool to prove your copy of Windows is valid.

1. Then use 7-Zip or another archive tool to open the EXE file as an archive.
2. Within that archive, find the "sources/xpm" file within it, and extract that folder to your hard drive.
3. Finally, in the extracted xpm file, you'll find a file called VirtualXPVHD. Rename it with a VHD extension.

In VirtualBox, open the VirtualXPVHD virtual machine, and voila! You've got Windows XP Mode (running Windows XP Professional) in Windows 8, no need for the XP license.

This might also be possible with Windows 8's built-in virtual machine manager, Hyper-V, but that's only available in Windows 8 Pro.

VMware ESXi 5 Update 更新 ( Command Line )

【安裝前的準備】
使用「esxcli software profile get」指令，查詢記錄更新前的版本及更新狀態，以便更新後驗證對照。

~ # esxcli software profile get    ESXi-5.0.0-469512-standard         Name: ESXi-5.0.0-469512-standard         Vendor: VMware, Inc.         ......

【開始系統更新】
開始更新 VMware ESXi 5.0 時，使用的「esxcli」指令是：

esxcli software vib install --depot 《更新檔路徑》

或是：

esxcli software vib install -d 《更新檔路徑》

順便加上進入「維護模式」的參數，一長串指令就像這樣：
esxcli software vib install --maintenance-mode -d /vmfs/volumes/datastore/update-from-esxi5.0-5.0_update01.zip 

【驗證更新結果】
再次使用「esxcli」指令查詢更新版本：

~ # esxcli software profile get
