MikTex 2.8 Downloading/Missing "ifxetex.sty" On Every Run

I debugged this problem after seeing my LyX on my Windows 7 machine taking so long to finish. I saw "latex" process was taking too long to finish. The I ran "latex" manually and the problem was obvious - "ifxetex" is being downloaded in every run.

This seems to be a bug in MikTex 2.8. The bug report can be found here: http://sourceforge.net/tracker/?func=detail&aid=3067362&group_id=10783&atid=110783

The solution is:
  1. Copy ...
                from: C:\Program Files (x86)\MikTeX 2.8\tex\generic\ifxetex\ifxetex.sy
                to: C:\Program Files (x86)\MikTeX 2.8\tex\latex\ifxetex\ifxetex.sty
  2. From Start-Menu > MikTex 2.8 > Maintenance (Admin), run "Update (Admin)" and update all pending update-able packages.
  3. Start-Menu > MikTex 2.8 > Maintenance (Admin), run "Settings (Admin)". and Then from "General" tab, click "Refresh FNDB" and "Update Formats"
MikTex should not download "ifxetex.sty" in every run now ;-).

Fantastic. I'm using Texniccenter and had the same issue. For me Hyperref was hanging during the compile. Thank you.

Another thanks from another happy customer -- had never met with the bug, but using Beamer today I was getting the nagging error message every time. Updated MikTeX to 2.9 and did as you said, fixed.
