Microsoft keeps more and more under C:\Users\All Users\Microsoft\ClickToRun\ProductReleases (also accessible via C:\ProgramData\Microsoft\ClickToRun\ProductReleases or more precisely %AllUsersProfile%\Microsoft\ClickToRun\ProductReleases).
This can be huge, running into 10s of gigabytes, which – for todays cloud, VM and light-weight device based world – is huge.
Compressing seems to fail for me consistently, as I get “access denied” while compressing when elevating from Windows Explorer.
So this is a reminder to sort this out eventually.
These did not help yet:
- compress “C:\ProgramData\Microsoft\ClickToRun” – Google Search
- [WayBack] Office 2016 Desktop Preview: how to remove Click-To-Run update – Microsoft Community
- compress” Microsoft\ClickToRun\ProductReleases” – Google Search
- compress “C:\Users\All Users\Microsoft\ClickToRun\ProductReleases” – Google Search
I don’t dare deleting it:
- [WayBack] Office Click to Run tidy up – get back wasted disk space – Office Watch
- [WayBack] Free up disk space after installing Office 2016 Click To Run
Hopefully it is something explainable like the a virus scanner.

Yup: it was the Avira Virus Scanner.
Somehow it has the Windows Explorer UI cause an “Access Denied” message to appear when elevating, but you can still compress files fine in a subdirectory with these steps:
Given a subdirectory named
C:\SomeDir\Ado this:
pushd C:\SomeDir\Acompact /c /s *.*cd ..compact /c Apopd
It is not the first time I bump into Avira stuff (but I only blogged about it once, dumb me: VirusTotal: Avira marks a Delphi built executable als false positive), but the decision of using it was outside my control.
