About this tag
The usebasicparsing tag on WindowsForum.com covers discussions about the UseBasicParsing parameter in PowerShell, particularly with Invoke-WebRequest and Invoke-RestMethod. Tagged content focuses on a December 2025 security change in PowerShell 5.1 that introduces a confirmation prompt when web content is parsed without explicit parsing mode. Users share guidance on how to suppress this prompt by adding the UseBasicParsing switch, which avoids the IE-based HTML DOM parser and uses a simpler, safer parsing method. The tag is relevant for IT professionals and scripters dealing with web content retrieval in PowerShell, especially in automation scenarios where interactive prompts are undesirable. Recurring themes include security updates, script compatibility, and workarounds for the new default behavior.
