Problem with Internet Explorer 8 Debugger on Windows 7

I continue to evaluate Windows 7 after upgrading from Windows Vista and share some experience (mostly bad of course, so people would not step on the same problem again). As I mentioned before, overall upgrade was smooth and mostly everything works OK. However time to time I stumble upon some really annoying problems that did not exist on Windows Vista and therefore need to be solved for Windows 7 from scratch.

One of the recent problems was Daemon Tools not working on Windows 7 and it was solved by installing Magic Disc. Now there is one more thing: after upgrading to Windows 7 I am not able to use IE8 Debugger. When I pressed F12 the Debugger icon appeared on the task bar but I can not switch to its window: it's not visible.

So obviously I searched over the Internet and luckily there was one post on Stack Overflow (apart from those guessing about a window being outside of the screen) that suggested that there may be some wrong setting in Windows registry. And there are some registry keys related to IE8 debugger! So the solution was to remove WindowsPos, Pinned and UseDevToolsDebugger keys from the [HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\IEDevTools] section. That completely solved the problem.

Unfortunately I can not tell whether those keys existed in Windows Vista and were incompatible with Windows 7 or their values have been incorrectly modified during the upgrade. But after removing them and starting IE8 debugger they haven't appeared again. So probably they are not needed anymore.

How to map .ISO file to a drive in Windows 7

So, recently I have upgraded my laptop from Windows Vista to Windows 7. The upgrade process was straight forward and flawless and everything so far was OK except one thing: the Daemon Tools that I've been using for mapping .ISO image files since 2004 on various Windows systems refuses to work on Windows 7. Even Windows 7 compatibility mode does not help: Daemon Tools manages to recognize Windows 7 anyways. Luckily there is another tool that provides with absolutely the same functionality and also free: Magic Disc. It works under Windows 7 flawlessly and really makes my life easier: no need to burn ISO files on CD/DVD anymore.
