Sandro Villinger from ITworld has hunted down a few new Windows 8 features.
The first is Crash Detection.
Microsoft seems to be fine-tuning its “PCA” (Program Compatibility Assistant) and overall stability of the system. Gathering from the group policies description, the PCA now detects denied access to deleted files as well as to system files (WRP, Windows Resource Protection) which in turn decreases issues that arise from these types of file system operations.
More importantly, Windows 8 tries to reduce crashes overall by isolating print drivers from applications. It’s safe to bet that this includes not only your general printer driver, but also “virtual” 3rd party drivers such as XPS, PDF or OneNote print drivers, which are often used to save files in a different format.
