Why is my computer taking a lot of time to shut down?

It might be downloading updates.

Also your computer will slow down if you have more than one anti-virus software running at the same time.

It could be the ram that your computer currently has installed.

Mine is the same way, and it’s annoying.

One thing to keep in mind is that any program that saves your place – like Firefox’s restart feature – has to store all that crap before it shuts down.

“Latest antivirus”.... Some AV programs are resource hogs.

Also, there is a bit of housekeeping that needs to be done before a system shuts down, and even more housekeeping if there have been recent updates. Having little enough RAM to make heavy use of Virtual Memory and it’s swap-file on the hard drive takes added time too. That is why I run Windows from an SSD instead of a hard drive; it’s absurdly faster.

Thanks All for your suggestions… I’ll check more on these lines.

If updates then schedule a time frame that is better for you in order that it will not interfere with your use on the computer.
Check on computer control panel to scedule these appropriate times.

Turn off Windows Auto Updates and also look at how many programs you have running before shutting off. The computer trying (and sometimes failing) to shut them down one-by-one on it’s own can slow things.

Do you have lots of apps or programs installed in your PC? If you do, you will have to wait for ages when you shutdown the PC.
