2010 year-end link clearance

Raymond Chen

Another round of the semi-annual link clearance.

And, as always, the obligatory plug for my column in TechNet Magazine:

  • Beware the Balloon.
  • Hiding in Plain Sight.
  • History—the Long Way Through. In their zeal to make this article meet length, the editors cut what I consider to be the most important part of the article! Here’s the penultimate paragraph in its full unedited version, with the important part underlined.

    But wait, there’s still more. What if you want to access the real 64-bit system directory from a 32-bit process? File system redirection will take your attempt to access the C:\Windows\System32 directory and redirect it to the C:\Windows\SysWOW64 directory. Programmatically, you can use functions with unwieldy names like Wow64­Disable­Wow64­Fs­Redirection, but those disable redirection for all operations until re-enabled, which causes trouble if you’re doing anything more complicated than opening a single file, because a complex operation may result in multiple files being accessed and possibly even worker threads being created. Instead of using a gross switch like disabling file system redirection, you can use the special C:\Windows\SysNative virtual directory. When a 32-bit process tries to access the C:\Windows\SysNative directory, the operations are redirected to the real C:\Windows\System32 directory. A local solution to a local problem.

  • Leftovers from Windows 3.0.
  • The Story of Restore.
  • The Tumultuous History of ‘Up One Level’. The editors messed up the diagram in this article. The “1” is supposed to be an “open folder” icon, but due to the same error that results in that mysterious J, the Wingdings glyph turned into a plain “1”. Here’s what the diagram was supposed to look like. (Of course, if your browser is one who believes that Wingdings doesn’t have a “1” glyph, then you’ll just see a “1”.)

    So for those of you looking for your Up One Level button, it’s right there on the Address Bar. I’ve drawn a box around it so it’s easier to see.
