Batch delete temporary Windows files (system, browsers, cache, etc) for all users

manpreet Best Answer 2 years ago

Is anyone in this community using a particular technique to achieve batch deletion of temporary data (such as Windows temp folders, browsers cache, etc) for all users?

The tricky part seems to be:

• Use a technique/tool that will be updated over time to meet changes in each product folder structure
• Allow access to other users folders (run as administrator/maximum privileges)

Scripts/batch files could be a solution, but it would require constant monitoring for each product update, to avoid deletion of older files/folder structures...

Your thoughts?

I had the same question, but motivated by the desire to aid my efforts to finish off malware cleanup operations. Here's the command script I wrote with an eye toward modularization so it could be extended easily for future OSes and temp file locations (I wrote this before learning PowerShell and haven't bothered to update it). Because it accesses every users profile folder on the machine as well as Windows system folders, the script must be run with elevated privileges.
