FiveChecks

FiveChecks measures compliance items (such as free disk space, pending reboot, system uptime, missing updates) at an hourly rate and writes the result to disk.

The result is checked on login and unlock of workstation and toast notifications are shown to the user when measurements are not within compliance range.

Notifications

The following notifications are implemented.

Check	Description	Notification
Pending Reboot	Notify the user if the machine has a pending reboot. Four reboot sources are checked for pending reboot. Any of the reboot sources can be excluded from the check through configuration. The notification can all together be disabled. The pending file rename operations source can be fine tuned with three different filters to exclude specific operations.
Missing MS Updates	Notify the user if there are MS updates waiting to be installed by the SCCM client and the configured wait hours have elapsed. Default wait hours are 48 hours. The notification can be disabled.
System Uptime	Notify the user if the computer uptime exceeds the maximum configured uptime hours. The notification can be disabled.
Disk space	Notify the user if free disk space is below the configured required free disk space value. This notification can be disabled.
Desktop Data	Notify the user if files other than shortcuts are found on the Desktop. Encourage user to store documents and data in My Documents or OneDrive. The notification can be disabled.
Password Expiry	Notify the user when password is soon to expire. The password expiry warning days are configurable. The notification can be disabled.

Developement

Code of conduct.

Do your best to be able to answer yes to the following questions when contributing code.

• Can this method or function easily be tested? (https://markheath.net/post/testable-code-with-pure-functions)
• Is illegal states unrepresentable? (https://enterprisecraftsmanship.com/posts/c-and-f-approaches-to-illegal-state/)

Any bugs have harsher living conditions and are more easily squashed when these two conditions are met.

Translation of resource files.

Resource files are translated using Visual Studio Extension ResX Resource Manager (https://github.com/dotnet/ResXResourceManager/releases)
