Does running Tor on Windows 10 compromise my security? And further from that, are there any issues I need to be aware of while using Tor on Windows 10?
Windows 10 has a keylogger embedded, thus all the words, codes, psws that user insert using keyboard could be sent to Windows Servers and to authorities per request.
Does it mean we should use "on screen" keyboard or other alternative input (speech) while using Tor? Unfortunately, Windows 10 has camera-logger embedded as well as microphone-logger embedded and a screenshot are pretty simple to make... hence, you almost should have on-screen input keyboard embedded in Tor, otherwise you are transparent.
I am afraid you cannot disable such a keylogging behavior by easy means, thus Windows 10 should compromise Tor as an incognito tool.
All in all, the overall impression using Tor on Windows 10 will compromise any of your activities including Tor usage.
