A repair install; isn't really an option as it is a preinstalled HP installation without disks and I am not 100% sure the license key on the box will work! I don't want to try a repair install from another DVD only to find the license won't work or activation fails!
A few weeks back I installed Win 7 pro on an HP using Dell media. The Win 7 home
key didn't work, but our companies MSDN/Retail key activated just fine (yes it was only for internal testing and therefore "legal" to do
). Point being their flexable. If you have any OEM media (for the correct edition), and a valid legible COA it should activate just fine. Some of the things that did activate (in tests I've run) were actually rather shocking.
I can't add folders to Winsxs even with admin permissions - I just get access denied.
If there is trouble in there, just use the .NET cleanup utility, and reinstall the .NET versions you need.
How can I reapply TrustedInstaller ownership if I take ownership?
I answered that a few posts above.
Better does anyone know how to reapply the standard security template to the Windows folder tree if I bugger about - I used to be able to do this to WinXP but I have never done it to Win7 x64 and Microsoft's Support site is now worse than useless - almost all the KB results you get take you to irrelevant community posts.
It's done using the secedit utility, but thinking after posting I do recall reading that that method doesn't "fix" folder perms in anything past XP. ...Sorry.
