| exitOnRebootDetected | Stop running install, upgrade, or uninstall when a reboot request is detected. Requires 'usePackageExitCodes' feature to be turned on. Will exit with either 350 or 1604.

| stopOnFirstPackageFailure | Stop running install, upgrade or uninstall on first package failure instead of continuing with others. As this will affect upgrade all, it is normally recommended to leave this off. | 0.10.4+ | |
| useEnhancedExitCodes | Chocolatey is able to provide enhanced exit codes surrounding list, search, info, outdated and other commands that don't deal directly with package operations. To see enhanced exit codes and their meanings, please run choco [cmdname] -?. With this feature off, choco will exit with 0, 1, or -1 (matching previous behavior). | 0.10.12+ | |
| useFipsCompliantChecksums | Ensure checksumming done by choco uses FIPS compliant algorithms. Not recommended unless required by FIPS Mode. Enabling on an existing installation could have unintended consequences related to upgrades/uninstalls. | 0.9.10+ | |
| usePackageExitCodes | Package scripts can provide exit codes. With this on, package exit codes will be what choco uses for exit when non-zero (this value can come from a dependency package). Chocolatey defines valid exit codes as 0, 1605, 1614, 1641, 3010. With this feature off, choco will exit with 0, 1, or -1 (matching previous behavior). | 0.9.10+ | ✓ |
| usePackageRepositoryOptimizations | Turn on optimizations for reducing bandwidth with repository queries during package install/upgrade/outdated operations.

| useRememberedArgumentsForUpgrades | When running upgrades, use the same (i. e. the remembered) arguments that were also used when a package was installed. This is helpful when running upgrade for all packages. This feature will be set on by default in future releases | 0.10.4+ | |
