Is it safe to delete "amd64" files from my Windows folder? My machine is a Dell using an Intel Processor, so why would I need AMD files?

If they are 'protected' how can I delete batches of them?

I am using Windows 7 x64 Ultimate

Your OS is using your Intel processor in AMD64 mode. It might be an Intel CPU, but the current 64 bit extentions come from AMD, hence their name. (Intel had other 64 bit plans, look up Itanium if you are curious about those.) –  Hennes Dec 7 '13 at 18:39

Do not. "AMD64" is the name for the 64-bit instruction set the x64 Windows is runs on. It just happens to be AMD who invented the 64-bit x86 instruction set, which Intel copied later on.

(Similar to how Intel invented the 32-bit instruction set for x86, and AMD copied it later on.) –  grawity Sep 4 '11 at 10:33
    
And amd64 is just "small extension" to "complete" x86 architecture developed (from scratch?) by Intel. –  Kamil Nov 26 at 15:42

Where the directory resides is important. You'll find files with these names in many locations. If they subtend a directory containing some string of fairly meaningless hexidecimal symbols, e.g., 12c8b0aaa7c55472e285280a, the subtending files and directories are probably garbage left over from an installation routine that was sloppily written.

First rename the aforementioned top level directory and run your computer for a couple days. If nothing seems amiss, then you're fairly safe deleting them. If they are locked, then you'll need to do some research on how to unlock them.

Please DO NOT attempt to mess around with the system32 directory. There are two reasons:

  1. This is ILLEGAL!

  2. Messing around with system files is disgusting and messy! Most of these files are undocumented, but they usually waste space for no good reason.

Even though this is the case, messing around with these files CAN RENDER YOUR COMPUTER UNBOOTABLE!

P.S.: Please don't say I told you so!

-1 for the fearmongering and baseless "ILLEGAL" claim. –  ʇsәɹoɈ Jul 5 '13 at 1:10
