WindowsClearCache

Simple scripts to clear temp files, browser cache/history, caches for applications like Microsoft Teams, Slack, Discord, Opera, and OneDrive, and remove Windows Defender scan and definition update backups (including the NisBackup folder), Windows dump files, and Windows Error Reporting (WER) temp files

How To Run

To run this with parameters, do the following:

1. Download the .zip file on the main page of the GitHub and extract the .zip file to your desired location, e.g. - c:\WindowsClearCache
2. Once extracted, open PowerShell (or PowerShell ISE) as an Administrator
3. Enable PowerShell execution: Set-ExecutionPolicy Unrestricted -Force (to allow executing unsigned code)
4. Run the Disk Cleanup utility (cleanmgr.exe) with the /sageset:1 option, which allows users to configure cleanup settings before executing the actual cleanup process e.g. - cleanmgr.exe /sageset:1
5. On the prompt, change to the directory where you extracted the files: e.g. - cd c:\Program Files\WindowsClearCache
6. Next, to run the script, enter in the following: e.g. - .\DriveClean.ps1

Optional flags:

• Use -DryRun to preview the files that would be deleted without removing them.
• Use -Verbose to display each file as it is deleted (or would be deleted in dry run).
