If you have a Windows 7 installation disk you can insert that in your drive and run SFCfix.exe It will find the missing files (if they're on the disk) and replace them. Although I can't find any documentation, if you place the missing files on the desktop (pertains to winsxs folder files), it will find them and replace them. Using SURT or SFCfix is advantageous, as apposed to replacing the files manually, in that it automatically takes ownership, installs the files, and then return ownership to TrustedInstaller. Manually taking ownership and restoring ownership is a pain in the A** and most times still allows you to access and delete or alter the files. This is exactly what viruses do, or try to, is alter system files and registry entries, as well as add it's files, folder, and rename files, folders, etc. It's very important that TrustedInstaller have full control of system files for that reason.

If you don't have a win7x64 Ultimate disc and would like one, you can download the ISO from Microsoft Download Center. You need to have your 25 character product key to do so. If you don't have that available, it is stored in the registry (binary form ones & zeros) I've attached a Visual Basic script that will convert the binary key to alphanumeric All you have to do is download & run it, either double left-click, or right-click choose>run. If your curious as to what the code is, right-click choose open.

You can't use windows copy and paste, which is for files, folder, etc., the ISO (image) has to be burned to disk. I use ImgBurn (free, I like free) a simple intuitive interface. The program has advanced features as well. Pretty much you choose the iso, right-click on the name area and a popup appears. I change the first and third entry, (I believe the first is ONLY_CAPS and includes underscore "_". It's always a good idea to have win7 installation disk, just in case you need to do repair install, which preserves all your files, folder, installed programs, video, music, etc.

The win7 ISO have all versions included, there is a file called, ei.cfg, you can remove it using a program, or manually, which requires converting the ISO to a folder on your computer, WinRAR again, finding the file and rename or delete it and recompiling the ISO, (I use free ISO creator) to convert the folder back to ISO. The automatic tool to do that is much faster/simpler ei.cfg tool.

You can create a batch file or Visual Basic file in Notepad, if you just save it, it saves as .txt, of you change the file type to all, you can add the suffix .bat or .vbs. You will notice the icon change accordingly.
