REMARKS Get-Help cannot find the Help files for this cmdlet on this computer. It is displaying only partial help. -- To download and install Help files for the module that includes this cmdlet, use Update-Help. -- To view the Help topic for this cmdlet online, type: "Get-Help Get-FileHash -Online" or go to http://go.microsoft.com/fwlink/?LinkId=517145 .

Answer 1

-Force

Overrides the once-per-day limitation, version checking, and the 1 GB per module limit.

Without this parameter, Update-Help runs only once in each 24-hour period, downloads are limited to 1 GB of uncompressed content per module and help files are installed only when they are newer than the files on the computer.

The once-per-day limit protects the servers that host the help files and makes it practical for you to add an Update-Help command to your Windows PowerShell profile without incurring the resource cost of repeated connections or downloads.

To update help for a module in multiple UI cultures without the Force parameter, include all UI cultures in the same command, such as:

Update-Help -Module PSScheduledJobs -UICulture en-US, fr-FR, pt-BR
