This should (in theory) change the start button, but here goes anyways. I did (or didn't, whatever you want to call it) do this on Windows 7 Ultimate 64-bit. Step 1: Get artsy Make a sweet picture of a nuclear trefoil from the Duke Nukem website. Step 2: Rambo, I choose you! Grab ResEdit x64, attempt to assume control of C:\Windows, and Explorer.exe - I apparently had trouble doing this right. Plan B: Copy Explorer.exe elsewhere. Step 3: Take the safety off Open new Explorer.exe with ResEdit, delete pictures 6801, 6805, and 6809, add the sweet trefoil 3 times (interesting...), rename one picture to 6801, the next to 6805, the last to 6809 (making sure that each of them are "English (United States)"). Save. Don't attempt to run the new Explorer.exe to see if it works. Step 4: Pop a few shots Attempt to write over the original Explorer.exe. Step 5: Miss Windows says I have to get permission to do that. Step 6: Grab a bigger gun Pop into Linux, teach Windows a thing or two. Step 7: Complain about the giant hole in your forehead Start Windows, around this time you should be greeted by a black screen and a message that says that Explorer.exe has crashed; if not, you are unlucky Step 8: Grab a band-aid Curse like a sailor. Pop back into Linux, notice that there are Explorer.exe.1 and Explorer.exe.2 in the Windows folder. Delete FUBARed Explorer.exe, rename Explorer.exe.2 to Explorer.exe. All in all, nothing was lost. If anybody knows how to do it correctly, do tell.
