Before you contact support.
Why does the installer request administrator approval?
OpenWithGuard installs protection components that must be available to Windows processes.
Can I pause protection?
Yes. Individual rules can be paused or removed, and global protection can be turned off.
Does OpenWithGuard upload my files?
No. File contents are not uploaded to provide association protection.
Where can I find my version?
The installed version appears at the bottom of the application sidebar.
