About this service

Office or home computers slowly fill up with temporary files, old logs and forgotten downloads until a disk runs out of space. This PowerShell script, which runs on Windows 10 and 11 with nothing to install, does the routine for you: it clears the temp folders and any folders you name of files older than the days you set, shows how much space it freed, warns when a disk has less free space than your limit and, from Standard, checks that named services such as a backup or print service are running and restarts them if you allow it. Nothing is deleted outside the folders and ages you give, and a check run lists files without touching them. Try it first on a test computer. No registry tweaks, speed-up tricks or turning off security.

What is included

• What you getA ZIP archive with the PowerShell script, a README with step-by-step instructions and, from Standard, a settings file with folders, ages and services; the code is also shown on the order page.
• Built into WindowsPowerShell comes with Windows 10 and 11
• Only by your rulesThe folders and file ages you set, nothing else
• Check runFrom Standard, a list of what would be removed, with nothing removed
• Disk space warningWhen free space drops below your limit
• Readable codeWith comments, easy to add a folder later

How it works

1. 1
   RulesYou list the folders, ages and services to look after
2. 2
   CodeWe write the script and the guide to running it
3. 3
   Try itYou run it on a test computer, first as a check run
4. 4
   ChangesYou ask for changes within your package and send any error message

What we need from you

The Windows version (10 or 11, Home or Pro) and whether the script may run as administrator, the folders to clean and how old files must be to go (for example temp folders after 7 days, a scans folder after 90), anything that must never be touched, the free space limit for warnings and, from Standard, the services to check by their names. How many computers it is for and whether they are in a domain.

We will ask you:

• Which computers is it for?
• What should it clean, and after how long?
• What should it check?
• Anything it must never do
