Apply to existing installation

[Donovoi]

This pull request introduces a new script, Invoke-Tiny11Cleanup.ps1, which enables users to apply tiny11 optimizations directly to an existing Windows installation without the need for a WIM image or reinstallation. The README has been updated with instructions for using this new live cleanup method, making it easier for users to reduce bloat and apply tweaks to already-installed systems.

New Script Addition and Documentation:

• Added Invoke-Tiny11Cleanup.ps1, a PowerShell script that removes bloatware, disables telemetry, and applies registry tweaks and optimizations to a running Windows installation. The script includes safety checks, user prompts, and logs actions for transparency.
• Updated README.md to document the new script, including a description, usage instructions, and warnings about modifying a live system. [1] [2]

User Experience Improvements:

• The script checks for administrator privileges and prompts to change execution policy if needed, ensuring smooth operation for users with restricted environments.
• Added clear prompts and warnings throughout the script and documentation to guide users and recommend system backups and restarts. [1] [2]

I applied this script to an existing 24H2 installation. Here's the log including a number of errors. Is 24H2 supported?

That simply looks like a lot of buggy code, should support 24H2 (& therefore 25H2) though

Hi ! I took a quick look, so I'll not speak about your code. But I'm not sure about this PR.

The main purpose of Tiny11 is to work with ISOs, and there are already many tools or scripts available for reducing running system sizes. Don't think it is good to mix both. 🤔
