Need current Win11 cleanup batch script and other

This script will irreversibly delete files. Be sure you want to delete these files primarily in the Temporary and Prefetch directories.You must run this script as an administrator to clean system files and directories. Consider backing up important data before running scripts like this, especially if you are unsure about any specific directories.

One of the biggest rookie mistakes is trying to run a script that needs elevated permissions without actually running it as an administrator. Tasks like deleting system files or clearing the Windows Update cache require admin access. 

Solution: Always right-click your batch file and choose "Run as administrator." You can even set it to always run as an admin by going to the file properties and adjusting the settings under the Compatibility tab.

Creating a batch script for cleaning up unnecessary files on Windows 11 can help improve system performance by deleting temporary files, clearing cache, and removing other unwanted data.
