I’m new to PowerShell, and I’ve been doing a lot of research. I’m using a Logging_functions library and a template I found on gist. From everything I have read the code looks correct(to my understanding, which isn’t a lot concerning PS), although I get no errors, and a log file does not manifest. The functions that I am calling from the Logging_functions library are all over place as I wasn’t sure where they needed to be and I tried to add the Log-Start and New-item lines in a few places and no matter where I put the lines in the code it wont create the log file. The Script is supposed to search the HKLM and HKCU registries and replace any strings that match a particular key word with a “0”
EDIT: Thank you guys for the input as I have refined the script, and removed a lot of stuff that was not necessary and I also removed the Logging_function altogether, as it did way more than I really needed, I replaced it with an Out-File write-output statement for what I need. What I have now is a script that runs without errors, and tells me that it is searching the two Registry Hives(HKCU and HKLM) for any type of string value named “skysail” and it is to change it to a “0” Well I’m not so sure my Set-ItemProperty statement is correct, as I’m not sure Dword is the right value type and I don’t know how to rephrase it to check for the string types that I need. When I look at on of the keys in a registry I need to “0” out it says it is a Default String.
