What is Task Host in Windows? Solved

Question

Hello,
my PC was working fine, I let my nephews play some games, now it’s running slowly, they must have pressed something, when I try to restart, it says "the task host is executing shutdown tasks", the program in question is "task host windows", I force the restart and it works a bit then I feel like everything tends to stop, programs take a long time to launch
how can I disable "task host windows" or how can I return to normal functioning?
I tried a restore but it’s the same
a big thank you to everyone who will help me resolve this issue

Configuration: Windows 7 / Internet Explorer 8.0

You can simply disable task host:

go to Control Panel, Administrative Tools, and open "Task Scheduler" or press Windows+R and type
```
taskschd.msc
```
In Task Scheduler:
- On the left, expand Task Scheduler Library > Microsoft > Windows and click on RAC
- In the central part, right-click on "Rac Task", select "Disable"
- If Rac Task does not appear, click in the View menu and choose Show hidden tasks.

If you are on Windows 10, the problem is rarer, but you can still try this:

Check that Windows 10 is up to date: Windows 10 Settings / Update and Security.
Temporarily disable your antivirus to see if it improves.

Try this:  Click on Start\Run, type msconfig.  Open the Startup tab, uncheck all programs,  Apply \ Ok  Restart and observe, be careful, avoid going online during this test  because the antivirus will likely be disabled, you will need to check them again.  Now it is possible that there is a not very reputable add-on  that has been inserted into the browser.  You will have to disable all of them, then reactivate them one by one while relaunching  it.

Hello,
I did a complete scan with Kaspersky Internet Security 2011 and it found the virus HEUR: trojan, it put it in quarantine and everything is back to normal
Malwarebytes didn't find anything, so for me, Kaspersky is the best antivirus on the market
thank you both again

have a nice day

Hello,  It's true that Kaspersky offers a good product and if I had to pay, that's the one I would choose. But what matters most is what we do on the PC, because I've seen completely infected machines even with Kaspersky.  If you're still around, I'd appreciate it if you could give me the name of the file and the folder where the HEUR:trojan was located, to better understand, thanks.  Best of luck  “Reason and logic can do nothing against stubbornness and foolishness.”

In fact, it belongs to EasyBits Software Corp., it is not digitally signed and sometimes it makes some antivirus software uneasy. The fact that it is alone reinforces my feeling (an active infection is generally composed of several elements).  It's strange because the file detected by Kaspersky has nothing to do with your problems, it's a known false positive by many antivirus vendors (Norton, BitDefender, etc... for example). The main thing is that everything is working again :)  Detections starting with Heur are files that have characteristics similar to malware after being analyzed by the heuristic engine, but not by the database. Generic means that it has not been completely confirmed as malicious because it is not listed in their database, so there is a higher chance that the file is mistakenly flagged and is not actually malicious.  source: https://bepick.net?p=13  I think that 100% security is hard to find, Kaspersky is among the best, I like it so I'm keeping it That was the gist of my thoughts.  Good evening

Hi,
I’m going to tell you exactly what I did
I first tried Start/Run then msconfig
under the "Startup" tab I unchecked all the programs as advised by morganch
I noticed it seemed to be working, so I enabled Kaspersky and ran the scan
since it detected something, I thought it was a virus
then I checked all the programs in "Startup" again and since 2 PM my PC has been working fine
what solved the problem, I don't know exactly given your "observations"
the important thing now is that it works, maybe I’ll think about formatting soon (since my PC is like an experiment, I do a lot of things on it to learn of course and improve, when I have a good level I won't make the same mistakes anymore)

thank you again for your availability

I restored to an earlier date when Windows Update had failed to update. So I restored from that date and now there are no more problems.

Hello, the Windows task host is an open door to your computer, regularly used by hackers but especially by authorities and the media to snoop into your private life. When someone intrudes into your private life, you will hear your computer working; this usually happens after you have made a comment on public sites. This open door is above any antivirus, as I myself have the very latest version of Kaspersky 2014, and they still managed to penetrate my pc... There is no way to stop them. When you hear your computer working and losing speed, and you try to restart it to stop this activity, you will be told that the Windows Task Host is in operation, and you will have to force it to stop. This application is part of the great scam of cyber intrusion into your private life, and there is nothing we can do about it.

Hello, so I’m making my modest contribution (if it can help...): having had the same issue, the problem (or rather the problems) doesn’t come from the antivirus, backdoors or anything of the sort, but from the different programs that are launched at startup, which have trouble closing naturally... when restarting or shutting down the machine. It’s a silly annoyance, but at M$ it seems like it has been working this way for ages...
For example, this problem occurred on a machine running WIN 7 SP1 64bit, and I solved the issue with CCleaner: go to the Tools menu, then Startup, and there disable the unnecessary programs at Windows startup, then restart to check (we can do this operation several times if necessary...)
In this case, it was Adobe Acrobat Reader that was the culprit; but depending on everyone's configurations, it could be other programs?

de passage provided the solution, stop overthinking, stop downloading so-called miracle software that, assuming they are good, bring their own Trojans and other crap, especially if they are free. A Windows problem? The solution is in 90% of cases within Windows itself. As in the case mentioned in this topic, I had the same slowdown problem, the impression that my computer was working on things I hadn't really asked it to, having to wait or force it to shut down... I followed what "de passage" advised and the problem was solved with a single click on "delete" or "disable" RAC TAC. Now if you haven't declared yourself the administrator of your computer, if you can't open system files, if you haven't given yourself full control access to your computer (a very simple procedure), you will have a hard time fixing the malfunctions of your OS which, apart from viruses coming from the outside, come from the system and therefore are in the vast majority of cases, repairable by the user after, most often, searching the internet. I am 73 years old, I am not a computer scientist, I got my first "computer" in 1980. PS. One of the multiple reasons that prevented my computer from running and shutting down normally was that it was waiting for the logoff sound from the explorer, too busy filling insignificant "tasks" otherwise.
