I've just checked the link, it was this one here: https://github.com/Nummer/Destroy-Windows-10-Spying/releases/tag/1.6.722 I downloaded and ran the DWS_Lite.exe To get the best optimum use Disable Windows Update from the Utilities tab first, then press Disable Windows 10 Spying on the main tab. Otherwise the Windows update will automatically run when it's restarted. Interestingly, I didn't do this, and when I restarted rFactor after the PC had restarted I got absolutely terrible stuttering. Then I checked my windows update and noticed it was updating, which suggests to me that Windows Updates are at least a partial contributer to the stuttering issue. Today I didn't experience any stuttering in any online race, although I haven't spent too much time on it. It may not completely fix the issue, but it should help. Also make sure you check the uninstall Metro apps checkbox, which is greyed out by default as the changes are irreversible.
