Issue: How to fix high CPU usage by HxTsr.exe?
I have no idea what the hxtsr.exe file is, but it keeps using too much CPU power (up to 40 percent), and my PC gets sluggish. Can I remove this file? Thanks for any help.
HxTsr.exe is a legitimate file developed and digitally signed by Microsoft Corporation. It's one of Microsoft's executables, which is known as Microsoft Outlook Communications. It comes by default along with Microsoft Version 2016, so it's not a core system's file.
Although HxTsr.exe does not compose the pack of essential Windows files, it an important integral part of Windows without which Microsoft Office programs may start malfunctioning.
However, this file is exceptionally prone to virus infections. In other words, legitimate files like HxTsr.exe are a good target for hackers to conceal malware. Due to vulnerability, this executable file has been marked as 42 percent dangerous, which is quite a lot. The original file's location is C:\\Program Files folder, so the first sign that its a malware, not a Microsoft Office file is alternative location, for instance, C:/Programs/System32.
Apart from virus infection, people reported high CPU by HxTsr.exe causing continuous mail app crashes. The others receive the “Microsoft outlook communications does not have a valid digit address” error, which indicates the HxTsr.exe as a culprit.
To fix high CPU usage by HxTsr.exe, you may need to reinstall Microsoft Office or fully optimize your PC with the help of a professional optimization utility, such as Reimage. That's because the HxTsr.exe error may stem from software incompatibility, the crash of some system's files or even driver-related problems.

In this case, you should try to install the latest Windows updates.
