No idea why this started happening (Not really anything has been installed or changed in the last couple of days) but quite a few things are crashing, for example, explorer.exe crashes when opening images (Using the 'Preview' thing) or opening the Games window, Defender simply won't start, start++ won't start, Nvidia control panel crashes, etc. Here is an example of Defender crashing: Problem signature: Problem Event Name: APPCRASH Application Name: MSASCui.exe Application Version: 1.1.1505.0 Application Timestamp: 45ad82d9 Fault Module Name: gdiplus.dll Fault Module Version: 5.2.6000.16386 Fault Module Timestamp: 4549bcaf Exception Code: c0000005 Exception Offset: 00032ad0 OS Version: 6.0.6000.2.0.0.768.3 Locale ID: 3081 Additional Information 1: 8d13 Additional Information 2: cdca9b1d21d12b77d84f02df48e34311 Additional Information 3: 8d13 Additional Information 4: cdca9b1d21d12b77d84f02df48e34311 Read our privacy statement: http://go.microsoft.com/fwlink/?linkid=50163&clcid=0x0409Each one of these error boxes from the various crashes mentions gdiplus.dll so I tried replacing the file with a 'fresh' copy, using regsvr to re-register it and just some other things but I haven't gotten anywhere. I really need to fix this. :/ I don't know what details would be useful, just a rather standard Vista [32Bit/Home Premium] setup.
