HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* |
Where-Object {$_.DisplayName -like "*$var*"}

Answer 1

Depending on your PowerShell version you either have to use the $using: prefix on your variable or you have to pass the variable using the -ArgumentList parameter. Here an example:

Invoke-command -ComputerName $cpu {
Get-ItemProperty HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\* ,
HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* |
Where-Object {$_.DisplayName -like "*$using:var*"}
