There is nothing as frustrating as a sluggish computer, especially when you’re trying to work against the clock to complete your projects or assignments in time. Normally, the first place users check when a PC starts acting up is Task Manager. And, if it so happens that the spike in disk usage is caused by the HxTsr.exe file, then you’ve come to the right page. Here, we will describe what HxTsr.exe is and how to decrease CPU usage by hxtsr.exe to prevent your PC from persistent freezing.

What is HxTsr.exe?

Usually, when dealing with .exe files, one has to remain skeptical until you’ve proven that the file is genuine. Most hackers disguise malware programs as .exe files to fool the targeted users into thinking that it’s safe. The genuine HxTsr.exe file is a component of Microsoft Office associated with Microsoft Outlook Communications. HxTsr.exe stands for Hidden Executable to Sync Remote Servers and comes already installed on your PC at the time of buying it.

HxTsr.exe is not a Windows system file and it appears to be a compressed file located in a hidden WindowsApps subfolder of C:\Program Files. While HxTsr.exe is not an essential Windows file, it’s required for Microsoft Office programs to function correctly. Removing the file from your PC might cause Microsoft Office Programs to malfunction.

Why is HxTsr.exe consuming so much memory?

There are concerns that the file might be a virus disguised as a legitimate Windows executable file. The sure way to know if it’s malicious software is to check its location. If the file is in a different location other than C:\Program Files\WindowsApps, then it should be considered as a Trojan or virus.

Attackers are capable of infecting, replacing or copying any executable file, so be wary and use a tool like Auslogics Anti-Malware, which is specifically designed to detect any kind of malware. It’s also advisable to perform regular PC scans to prevent falling into the trap of hackers. If you verify that the file is legitimate, you can whitelist it so that your antivirus software skips it during future scans.

Another complaint is the high disk usage caused by HxTsr.exe. This could be due to Outlook or Microsoft Office services running in the background. According to some users, the disk usage was at a constant 100% leading to sluggish performance.

How to fix the problem of high CPU usage by HxTsr.exe

Before you get into any complicated processes, we recommend optimizing your computer to check if it resolves the problem. Sometimes, lack of sufficient disk space, unnecessary programs running in the background, web browser cache, browser extensions, and huge chunks of PC junk can slow down your computer.

The best approach is to run a tool like Auslogics BoostSpeed to fully optimize your operating system so that it can perform at its optimal level. This tool is highly effective and comes with other useful utilities that your computer needs to run without lag or the constant freezing and crashing.

After running the various modules that Auslogics BoostSpeed has to offer, restart your computer and open Task Manager to check if disk usage is still registering a high percentage. If it does, then try one of the solutions provided below.

Fix 1: Update Windows

  2. Select “Apps”.
