“重命名项目”使用新名称进行复制

Question

Trying to make a script to backup specific folders and then rename the GUID key for the target user under HKLM...\\ProfileLists but the rename-item command makes a copy of the key and creates a new key with the appended name though having full access

Tried with -force, tried with move-item instead of rename but it gives the exact same results, a new identical key as original but with an appended name

if ((Test-Path $FULLPATH)) { 
    Rename-Item $FULLPATH -NewName "$SSID.bak" -Force 
    if ($?) { 
         Write-Host "$USERNAME was SUCCESSFULLY renamed in the registry" 
    } 
} 

Expected result is to only rename the GUID-key in the registry. Actual result is a duplicate key with the new duplicate to have the correct appended name.

Rename-Item : The registry key at the specified path does not exist. At line:9 char:5 + Rename-Item $FULLPATH -NewName "$SSID.bak" -Force + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : InvalidArgument: (HKEY_LOCAL_MACH...\\folderredirect:String) [Rename-Item], ArgumentException + FullyQualifiedErrorId : System.ArgumentException,Microsoft.PowerShell.Commands.RenameItemCommand

Rename-Item : Object reference not set to an instance of an object. At line:9 char:5 + Rename-Item $FULLPATH -NewName "$SSID.bak" -Force + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (:) [Rename-Item], NullReferenceException + FullyQualifiedErrorId : System.NullReferenceException,Microsoft.PowerShell.Commands.RenameItemCommand

The key does exist and I can run the same command again as proof (due to the test-path).

Verbose output do confirm its copying

VERBOSE: Performing the operation "Copy Key" on target "the key in question"

Answer 1

It works for me. Are your variables set in this way?

$SSID = 'S-1-5-21-1212123708-1212126490-1212120831-1001'
$FULLPATH = 'HKLM:\Software\Microsoft\Windows NT\CurrentVersion\ProfileList\S-1-5-21-1212123708-1212126490-1212120831-1001'
rename-item $fullpath -newname "$SSID.bak"

I was unable to rename the keys with rename-item with full paths and not using variables either. However resolved it by replacing rename-item to

# Rename the Registry profile if ((Test-Path $FULLPATH)) { reg copy "HKLM\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\ProfileList\\$SSID" "HKLM\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\ProfileList\\$SSID-$(Get-Date -f yyy-MM-DD)" /s /f if (( $? -eq 'True' )) { reg delete "HKLM\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\ProfileList\\$SSID" /f } if (( $? -eq 'True' )) { Write-Host "$USERNAME was SUCCESSFULLY renamed in the registry" }

had to use half the full path in the reg copy/delete commands as the syntax is different (no colon). This worked
