Windows 10: Using Windows Update to repair some system32 files

Hello,I accidentally emptied the "0409" and "Advancedinstallers" and probably some other folders in System32 via command promptLuckily, most of it gets blocked, but some files are slipped through.I immediately fired up the system restore tool..I know the other options already.But, can i still repair accidentally broken parts of System32 using the updates from Windows Update?Ruben

Repairing Windows

Every time I boot up Windows, I get an error that says I need to repair (it says it's missing a file). I've been reading that in order for me to repair my Windows installation without loss of data, I need to delete a file called undo_guimode.txt in the system32 folder. I open up the recovery console and type in del /a /f C:\Windows\system32\undo_guimode.txt and it says "The parameter is not valid." Now, I'm not sure if this means that the file doesn't exist (which is good news for me, meaning I can just go ahead and install) or if it's hidden, or I'm not doing it right, or something. If anyone could help, I'd really appreciate it.

Thanks in advance.

Repairing Windows XP can Break Windows Update

Microsoft/Windows Update Program Manager Nate Clinton has revealed that repairing a Windows XP installation using the Windows XP CD can potentially lead to users being unable to install updates when using the latest version of Windows Update. The problem, which does not appear to be widespread, occurs because the Windows XP CD replaces all system files, including those of Windows Update. Because the latest version of Windows Update uses a file which is not present on the Windows XP CD this causes a registry mismatch which can result in Windows Updates failing. So if you have recently run a repair install on Windows XP it is recommended that you either take a look at KB article 943144, check here for a workaround or contact Microsoft.
