Hi people. I have an Acer Aspire 5920 notebook. It has Windows XP Professional + SP3 installed on it. I was hit by Brontok last week. Now, I wish to nuke all existing partitions, re-create new ones, and install Windows Vista Ultimate + SP1 from scratch. I have a copy of the Windows Vista + SP1 DVD (32-bit, MSDN, SHA-1: bcd715a02739809e477c726ae4b5caa914156429). However, creating another copy of the same (with the Acer SLP key and OEM activation certificate integrated) is not an option for me, given the badly infected state my machine is in. I've searched the forums for a solution, and came up with one. This is how I plan to proceed: a. Install Windows Vista Ultimate using a known Acer SLP key (I'll probably use one from this list.) b. Acquire a copy of the Acer OEM Activation Certificate (acer.xrm-ms) for Windows Vista Ultimate (from here.) c. Install it using the command: Code: slmgr.vbs -ilc <path to acer.xrm-ms> Could the forum elders please tell me if there's anything wrong with the above technique? Thank you.
