file is not detected as an infection by almost all antivirus softwares. BUT by purging the file from many systems helps me terminate many issues like slow systems. also i noticed that many systems infected by a spyware are containing the htpatch.exe file. One of the system i fixed was fixed by renaming a copy of any txt file by htpatch.exe right after deleting the real .exe file. the spyware just stop regenarating after that manipulation of the htpatch.exe file.

I agree with Mirek's assessment of nuisance factor. Search your mainboard's AGP driver installer folders for "HTpatch*" There may be a "HTuninst.exe" file in the same folder. Run the HTuninst.exe to cleanly uninstall HTpatch.exe references from the windows registry. C:\windows\htpatch.exe file will not be deleted but that is harmless to leave around.

if you dont have hyperthreading, it does nothing. it just sits there and takes up ram. it might slow down your comptuer a tad if you dont have a lot of ram. thats about it.
it is a agp driver for a sis motherboard but if you dont have a pentium then it can cause problems with internet explorer and windows media player.

Best practices for resolving htpatch issues

A clean and tidy computer is the key requirement for avoiding problems with htpatch. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the htpatch.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
