Working with providers

1. In the Registry, go to HKEY_CURRENT_USER\software\microsoft\Windows-currentversion\explorer. Locate the Advanced key, and set its DontPrettyPath property to 1.

Set-Location HKCU:

Set-Location .\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer

Set-ItemProperty -Path .\Advanced -PSProperty DontPrettyPath -Value 1

---

2. Create a new directory called C:\Labs.

Set-Location C:\

New-Item -Name Labs -ItemType directory

---

3. Create a zero-length file named C:\Labs\Test.txt (use New-Item).

Set-Location C:\Labs

New-Item -Name Test.txt -ItemType file

---

4. Is it possible to use Set-Item to change the contents of C:\Labs\Test.txt to TESTING? Or do you get an error? If you get an error, why?

Set-Item .\Test.txt -Value TESTING

output:

    Set-Item : Provider operation stopped because the provider does not support this operation.
    At line:1 char:1
    + Set-Item .\Test.txt -Value TESTING
    + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        + CategoryInfo          : NotImplemented: (:) [Set-Item], PSNotSupportedException
        + FullyQualifiedErrorId : NotSupported,Microsoft.PowerShell.Commands.SetItemCommand

---

5. Using the Environment provider, display the value of the system environment variable %TEMP%.

Set-Location Env:

get-ChildItem *TEMP*

output:

    Name                           Value
    ----                           -----
    TEMP                           C:\Users\debressa\AppData\Local\Temp

---

6. What are the differences between the -Filter, -Include, and -Exclude parameters of Get-ChildItem?

Include and Exclude both work after the cmdlet has retrived its objects, Filter works while the cmdlet is retriving objects

Include and Exclude both require Recurse to work, Filter doesn't require Recurse

Filter will not work in the Registry since Registry uses differing PSProvider structure
