Yo can desactivate completly all telemetries, if you want. But it isn't very usefull. Privacy is often misunderstood, a privacy problem can be when personal data is leaked, your activities on- and offline, but not so much technical details of your PC in case an error report is sent for a driver or other issue, if they send a report about the version of Windows, searches for security updates and patches, things like that that do not compromise privacy at all, because it is data that is identical to millions of other users who use a similar system. Alll other you can block, desactivate or desinstall, apart simply avoiding to use EDGE or Bing por searches, using instead you prefered browser and search engine, which you surely do. I use the Portmaster app, with which I controll all the outgoing and incomming traffic, even blocking it if needed, because of this I know that there isn't any strange thing that compromises privacy.

Yes, no much problem with the cleartext software part, but the other where you see only numbers are not so easy, just easy to turn your PC into a Paperweight. This really isn't very intuitive

Easier the Services, although you can also screw up there

Use Winternals sysmon to suss out problem registry keys and file permissions and their minds will be blown.

I mean, hes not wrong if hes talking about Windows 7.

if hes talking about 10 or 11, then the dudes clearly on LSD.

Read also the rest what is necessary to make Windows private and stable. Nothing new that Windows by default is a privacy nightmare, but you can change it, but how to do this is not in the Windows Helpfile.

I know all this, I already mentioned elsewhere that I laugh when some users say they don't use Linux, because it is an OS for advanced users. No, it is precisely Windows that requires a more advanced user than Linux, when you really need to modify something, which naturally cannot be done with the GUI and requires using the console (cmd). On Linux this is the rule for everything (although less and less), on Windows you can do most of it with GUI, but not all of it, if you don't want to use a third party app. In General Windows is only easier and more intuitive to use superficially, but in depth it is a minefield, much more complicated and less intuitive than Linux.

Yes, there are some tools which can help, eg https://github.com/hellzerg/optimizer, also Windows itself has the GodMode, but it need somewhat more than this and only remove Skype, MS Store and Cortana.
