The Microsoft Surface Pro 6 and previous iterations try to combine the best of tablets and full Windows 10 PCs. While the idea mostly works, the consensus is that Surface is not as good at being a tablet like an Apple iPad. Some of that is due to hardware, some of it is about the software.
One area that can be improved is touch responsiveness. This function is thought to be achieved through a simple registry change on the Surface Pro (any generation) or any Windows 10 PC with touch support, like the new Samsung Galaxy Book2.
What this touch trick does to your PC
In the Windows 10 registry, there are settings to change latency and sample time, both of which will increase the responsiveness of the touch display when decreased. The potential downside, as mentioned above, is decreased battery life. However, many users who make this change say any shift in battery life is imperceptible to detection, or at least not apparent.
Article dispute: Brandon Paddock from Microsoft notes this trick does not quite do what some think it does:
"This value does NOT change the polling frequency or sample rate of the touchscreen. All it does is lie to the prediction engine about what those values are, breaking its ability to correctly do its job... All it does is lie to the prediction engine about what those values are, breaking its ability to correctly do its job. At best you are giving invalid values that it ignores."
As always, we'll leave it to the user to determine if the experience is worse or better for themselves. Just know that Microsoft evidently does not support or endorse this modification or our article.
If you do notice a massive downgrade in battery or other anomalies, you can quickly revert the registry change and return to normal.
It is important to note that if you're using Windows 10 in S mode, like how the Surface Go or Galaxy Book 2 ship, you cannot access the registry in that configuration and would need to switch out of S mode for this to work.
Finally, the difficulty and risk factor for this "hack" is as "easy" and "low."
How to change touch sensitivity in Windows 10
Since Microsoft does not offer a way to alter touch sensitivity through the Windows 10 OS, the most direct way to do it is through the registry.
Warning: Modifying the system registry can have dire repercussions if not followed precisely, including driver failures, system instability, or not being able to boot into Windows. Users are always encouraged to run a system backup before making any changes to the registry.
To increase or decrease touch responsiveness on your PC, follow these steps:
- Type in registry editor into the search box.
- Click yes on the User Account Control window.
- Navigate to
- Double-click on Latency and change value from default 8 to 2 (or less) in the Value Data box.
- Hit OK when done.
- Double-click on SampleTime and change value from default 8 to 2 (or less) in the Value Data box. Hit OK when done.
- Close the Registry Editor.
- Restart PC to make sure changes take effect.
The exact value to set Latency and SampleTime to is arguable. Most users configure it to "2," but others have set it to "1" or even "0", which presumably makes it even more responsive. Due to the likely hit on battery life setting it to "2" seems like the best choice, as it delivers a substantial improvement without any noticeable side effects.
Does this really improve touch responsiveness?
If you frequently use the touchscreen on your PC, then yes, this does make the PC feel much more natural, fluid, and responsive. As to how much value you get out of it – and whether it substantially affects battery life – is up for debate, but there does not appear to be any dramatic negative consequences hence why we are suggesting it.
The more interesting question is why Microsoft does not set a lower default value. The immediate explanation would appear to be to maximize battery life. One solution for Microsoft could be just to put this under Windows Settings and let users have access to a slider with a small warning that increasing sensitivity could impact battery life.

In the light of the just announced bad*ss iPad Pro, that in combination of the Adobe announcement totally wrecks Microsoft, publishing this article about how to correct the touch responsiveness of ancient Windows OS WITH A REGISTRY TRICK is just laughable, not to say - pathetic. It's funny how after every Apple event, Apple makes Microsoft looks like a dinosaur, irrelevant and ancient as it gets. I wonder who would get first to the dream - Microsoft making the ancient Windows a modern OS, or Apple adding a mouse support to iOS? If I were Nadella, I would be worried about the answer to this tick-tock tick-tock. Rubino, why did you delete my post when I first added it and your own tweet pointing to this article? Looks like my comment is on point and telling the bitter truth?

Like bleached, but not depressed.
I have to admit that was pretty funny.
iPad Pro hasn't changed much. Still doesn't run full Mac OS.... very unfortunate that a PRO device is still not pro, just ios on a big screen. I personally like the Surface Pro versions much better. At least I can have steam on it and play real games and do everything else you would do with a tablet. It doesn't make sense reomw to hate on a site for info about windows. We didn't come to this site to read your comments about boring apple products.
You don't think iOS polls the screen for touch input? Not understand technology is fine, but that should make you want to learn more, not... Do whatever it is you were trying to do, lol.
I'm not sure "polling" is the best word for it, but yes all touch sensors have a refresh or sampling rate, as do mice and pen digitizers, for example. This is measured in Hz, or number of times per second that it refreshes. This number is tied to the touch controller hardware and firmware, and is not controlled by this registry key or any other.
@Reomw, there is no need to "correct" touch responsiveness on Surface devices. This "trick" does literally nothing for 99% of touch input, and actively breaks it for certain multi-touch gesture scenarios. The registry keys being modified do NOT affect the touch sensor in any way. They only mess with values used by the multi-touch gesture recognizer's prediction engine (e.g. for pinch-zoom). Do not make these changes.
Would this affect pen input? And if not, is there another setting that would?
It seems to for me. I have a Spectre X2 and the Wacom stylus is unusable but after I did this it seems to be running smoothly! Sample time and latency on 1.
Should be zero effect on pen. Re: another setting, unlikely, at least not user-facing via registry AFAIK, but will look around. That is likely drive-level changes.
These values have no effect on pen. They have virtually no effect on anything, and do NOT alter the behavior of the touch sensor or the code that processes general touch input. The only possible effect is to mess up multi-touch gestures like pinch-zoom in UWP apps. Also, Daniel... Registry keys are not "user facing".
It did not do anything for me Daniel. I have a surface pro i5 2017.
It does nothing. The only possible outcome is making multi-touch gestures worse.
Umm ... so, dude from MS says don't make these changes. Emphatically.
Thanks definitely improve the accuracy of my little HP Tablet.
