Learn to execute a PowerShell script by configuring execution policy and by specifying a script path or using period backslash for the current directory.

Launch PowerShell scripts from desktop shortcuts by configuring a shortcut to call PowerShell.exe with bypassed execution policy and the target script. Double-click to run and quickly execute.

PowerShell variables store data as underlying .NET objects, declared with the dollar sign or the new-variable command, and use explicit types to prevent unintended changes.

Create constants in Power Shell by converting variables to read only or constant using set variable, preventing overwrites; remove variable to redefine as a true constant with a new name.

Master PowerShell comparison operators, including -eq, -lt, -gt, -ge, -le, and -ne, learn string comparisons with case sensitivity (-ceq) and default case-insensitive behavior, and combine conditions with -not, -and, -or.

Explore the if statement in PowerShell to branch scripts with conditions, use else if and else for multiple options, and apply comparisons like day equals 12 in practical examples.

Explore looping constructs in PowerShell: for each, for, while, do while, and do until, and learn how each handles condition checks and iterations with arrays and strings.

Explore PowerShell looping constructs with do while and do until, including hands-on coding tips, execution order, and how to run and modify sample scripts in your working files folder.

Explore regular expressions in PowerShell, covering literal and pattern matches, case sensitivity, quantifiers, escapes, and shortcuts like \d, \w, and \s.

Explore part two of regular expressions in PowerShell, using dot net framework patterns to validate IP addresses and Social Security numbers with practical examples.

Learn to use the escape character and comments in PowerShell, including the grave accent for new lines, tabs, line continuation, and embedding quotes in output.

Learn how to pass input parameters to PowerShell scripts using the parameter block, including mandatory parameters, data types, and practical examples to tailor scripts to objects and conditions.

Explore how PowerShell providers expose drives, with the file system provider as the default, and use commands like get-location, set-location, and new-item to work with PS drives.

Learn the Windows PowerShell file system provider, the default for managing files and folders, and use Get-ChildItem with Set-Location and -Force to inspect the mode column and reveal hidden files.

Learn how the PowerShell alias provider lets you map short names to commands like get-child-item and set-location, speeding workflow. Create, manage, and persist aliases across sessions using profiles.

Explore the variable and function providers in PowerShell, using the variable drive to view and create dollar-sign variables and the function drive to define and call reusable code.

Explore the certificate provider in PowerShell to view certificate stores, export details to CSV, and open data in Excel, with tips for current user and local machine scopes.

Explore how Windows PowerShell simplifies managing files and folders, using Get-ChildItem with -Force and -Recurse, filtering by last write time, and parameterizing scripts for flexible file discovery.
