Note from the shelf row: run it in the quiet hour

Before you install

  • Runs on: Windows, Linux, macOS. the application must be 4.0.7 to 4.1.6.
  • Space: about 210 KB for the download, plus [WORKING SPACE] while it runs.
  • Rights: an ordinary user account; no elevation needed
  • Know first: [PREREQUISITE] — what has to be true before this tool will run at all.

Download and verify

Take the build for your platform from the [SHARE] and check it against the digest on the shelf row before you unpack anything.

certutil -hashfile regshadow-3.1-win64.zip
md5sum regshadow-3.1-linux-x64.tar.gz
md5 regshadow-3.1-macos.tar.gz

Expected: f498d3343781. The shelf row carries the same digest.

Install

Copy it into place and put it on the path. Nothing here installs a service or a scheduled task.

Windows

Unpack the zip, then: 

xcopy regshadow-3.1-win64 C:\Tools\regshadow /E /I
setx PATH "%PATH%;C:\Tools\regshadow"
regshadow --version

Linux

Unpack it and link it onto the path: 

sudo tar -xzf regshadow-3.1-linux-x64.tar.gz -C /opt
sudo ln -sf /opt/regshadow/regshadow /usr/local/bin/regshadow
regshadow --version

macOS

Unpack it and link it onto the path: 

sudo tar -xzf regshadow-3.1-macos.tar.gz -C /opt
sudo ln -sf /opt/regshadow/regshadow /usr/local/bin/regshadow
regshadow --version

Check it worked

Check the version first, then run the one command the tool exists for:

regshadow --version
regshadow compact --reclaim
reclaimed 2.4 GB in 3 min 12 s

Expected output is the line shown above; anything else means [TO DO: write the failure list].

Removing it

Delete the folder and drop the path entry. The tool keeps no state of its own.

rmdir /s /q C:\Tools\regshadow
sudo rm -rf /opt/regshadow /usr/local/bin/regshadow
sudo rm -rf /opt/regshadow /usr/local/bin/regshadow

If it goes wrong

  • [KNOWN FAILURE 1] — the usual fixes for this tool have not been written down yet. Add them the second time somebody hits one.
  • Wrong error number or a fault you cannot name: run the tool's own diagnostic first (shelf row).
  • Before any repair that writes to a store, take the export — backoff is the tool for it.
