A Hotfix is a product update package with one or more updated product files that fix a specific product problem.


Please be aware this Hotfix has not gone through full Microsoft product regression testing nor has it been tested in combination with other Hotfixes.

Issue Description

VS2008 SP1: In Visual Studio 2008 SP1, having windows in non-default locations, for example after docking and undocking windows, when switching between debugging and designing or switching to/from full screen, can result in a crash of the Visual Studio IDE.

This Hotfix was updated on May 11, 2009 to address a shortcoming with the original Hotfix (published Mar 12, 2009) whereby XAML Intellisense may cease functioning after applying the Hotfix. If you have applied the original Hotfix, it is not necessary to uninstall it to apply the updated (V2) Hotfix.

Additional Information about the issue resolved by this Hotfix can be found in its Knowledge Base article at

This hotfix breaks intellisense for XAML files, and it causes XAML files to fail to display the + and - outlining buttons to the left of XML elements. Both symptoms are corrected by uninstalling the hotfix, and they both return when the hotfix is reinstalled.

I experienced the same issues listed by RoySprowl on Vista X64.

I experienced the same issue described by RoySprowl above. Instead of uninstalling the hotfix, I ran the repair utility on VS. Once VS finshed repairing XAML intellsence and the epxand collapse region came back...
Seems like all the crashing issue started after I installed the Windows 2008 and .Net 3.5 SDK.

I followed Ryszard's advice - installed the hot fix, then ran repair on VS - the crash issue is resolved and I've retained intellisense on XAML files.

This hotfix breaks the "Team Settings" feature entirely. Selecting a team settings file will result in an environment reset and the team settings file selection will not persist.

Running Window->Reset All Windows fixed this for me and I didn't have to do the hotfix.

I used the Window -> Reset All Windows as suggested by LoneCoder, and that fixed the problem for me, without using the hotfix.

llichty's solution worked for me without installing the hotfix. Thanks!!

OK, so I got the error, and after applying the hotfix it completely corrupted my SmartClient Software Factory Project!

I used "Window->Reset Window Layout" and it fixed my crashes.

I tried the "Windows | Reset Window Layout" method mentioned above and it did not fix the issue I was having. I was unable to set up VS2008 with the tool windows undocked; every time I exited the application or switched modes (code/debug) the application would crash.

Running this hotfix was the only way that I could find that would enable me maintain my undocked tool windows.

Is the llichty fix about "Windows > Reset All Windows" meant to simply avoid the crash? Or does it allow you to drag your panels wherever you want to? I've tried it and no matter what, if I move my Solution Explorer panel to my 2nd monitor I get a VS crash on exit. So annoying!

Glad i found this, it finally fixed my endless crashes. I was wondering whether my program was causing those crashes!!! and the layout for my debugging windows is finally persisted!

Seems fine to me. Win2008 x64/VS2008/Using two monitors - one for VS2008 main and one for most other windows (undocked). Was crashing regularly but now seems to have stopped (albeit early days, YMMV!). Tried using XAML and it still seems ok - no need for repairs or otherwise. [Reset Windows Layout didn't cure mine either - I think it just avoids the issue, but I may be wrong].

What is the "repair utility" that Ryszard is referring to? Is that the repair tool that's in "Add/Remove Programs" in the Control Panel?

This will work for the intellisense problem.

I was able to perform "Window --> Reset Window Layout" and it fixed VS.

Since I didn't want to apply the hotfix and the given workarounds did not work for me I played around a bit. After deleting the .suo (and .ncb) file, opening the solution, repositioning the windows, File->Close Solution, closing VS, it was working again. :-) I'm using the main window on 2nd monitor and tool windows on 1st monitor.

try deleting CurrentSettings.vssettings from C:\Users\<insert-your-username>\Documents\Visual Studio 2008\Settings it fixed it for me... I'm guessing that this is the same as the Reset All Windows suggested above, but i'm not sure...

Thank you to those who suggested Window --> Reset Window Layout. It fixed my problem perfectly and I didn't need the hotfix.

Reset Window Layout did the trick for me too. Perhaps you guys at MS should consider adding this as a first choice solution to KB960075 before suggesting the hotfix?

VS is occasionally crashing on me when trying to debug. Windows error reporting is pointing me to this KB.
It happens when I dock the Properties pane to below the Solution Explorer pane on the right.
Then when you debug VS moves the Properties pane back to a tab in the main Solution Explorer pane and it crashes.

The 960075 hotfix did NOT work for me. Nor did the Window > Reset Window Layout trick.

Win 7 Pro / 64 bit / Visual Studio 2008 SP 1

I can reproduce the issue every time: open any aspx page in source view, switch to design view and it locks up the interface. Nice... And yes, I tried a new project with a basic aspx page.

This hotfix worked for me. My issue was if I ran my debug exe's and then moved the windows around, once I stopped execution VS would crash. The reset window layout did nothing for this type of problem.
