Do not use Intel XTU on your laptop

There are several reasons that throttlestop is highly recommended over Intel xtu

XTU impacts performance. "Based on those results it is obvious that leaving Intel XTU running on your computer is not a good idea. Even when it is minimized to the system tray and not doing anything, it is still significantly reducing the performance of your laptop."

TS is more stable than XTU. Because TS works only on the software, it is more stable. There are many reports of XTU not working after waking the laptop from sleep, while TS does not have this issue because the program starts back up after waking.
Because TS is software based only, it does not make changes to the bios unlike xtu. this means that there is almost zero risk of any permanent bricking or changes. In addition, because it's software based only, simply delete the .ini file that contains all the settings and then all of your throttlestop configurations are removed.
XTU is fucky, and by that I mean it seems to be almost impossible to complete uninstall, at least in my experience. I've ever been able to delete all traces of XTU from a system before at least without doing a full windows reinstall.
There's just less customizations you can do with XTU like changing the EPP settings
