Kernel_task keeps using more and more memory, threads. How do I fix this?

In Activity Monitor, kernel_task (PID 0, User root) doesn't take up much CPU, but has a huge number of threads open. It also has nearly 400 MB of real Memory, and over 4 and a half GB of virtual memory! This is slowing my computer down immensly. I tried restarting the computer, but it didn't help. Any tips on how to fix this?

But not necessarily the same problem. Would you go to your doctor and say "You examined a friend of mine and I have the same symptom, so what's wrong with me?"
Large amounts of virtual memory are not abnormal. All that means is that the system has pushed a bunch of recently used data off onto disk to free up ram for other processes. If the processes you're running collectively need more active memory than you have installed in the machine or if you're boot volume is almost full things can slow down dramatically, but otherwise the size of virtual memory is not all that relevant.
pid 0 on my machine has 95 threads open, 700 Mb real memory, but only 49 Mb virtual memory. 4.5 Gb of virtual memory sounds excessive and my guess at a cause would be some third-party app or plugin or some such with a memory leak. As a diagnostic, try restarting in Safe Mode and see if the problem is still there. If it goes away in safe mode, then you'll to have to tell what 3P processes you normally run.

Hi lepyykko,
If I understand your question, you are trying to update your iPhone, but you are seeing an error message that iTunes for Windows is not installed, is that right? The first step is to get iTunes successfully installed on your computer. Then backup the iPhone before updating the iOS software.
Are you seeing any error messages when you try to install iTunes for Windows?

my iphone 5 wont let me update apps keeps popping up with old apple id how do i fix this??

All apps downloaded/purchased are tied to the apple ID used to download/purchase them.
If you change your Apple ID and do not wish to use the old apple ID and password to update them, you have to delete them and redownload or buy them under the new apple ID.

As I said in the other thread that you posted in the other forum, your friend clearly has not restored the iPad correctly. I suggest that you undertake another restore and start again.

"Sounds like you guys are using the same apple id for imessage. You will need to create a separate id for you wife. OR go to settings - message - receive&send and make sure your phone number is the default for both you and yoru wife.

my daughter and i logged onto same icloud and now i can see her messages and vice versa.. how can i fix this?

This isn't being caused by your iCloud account. It's caused by using use the same Apple ID for iMessage. To fix this you have two choices:
On one of the phones go to Settings>Messages>Send & Receive, tap the ID, sign out, then sign back in with a different ID (so both phones are using a different ID for iMessage). Note: you can still share the same ID for purchasing in Settings>iTunes & App Stores; or
On both phones go to Settings>Messages>Send & Receive and uncheck the email address(es) shown under "You can be reached by iMessage at". Also uncheck anyone else's phone number, if present.

You can search the entire internet by putting that error message into google, see what other discussions appear.
With only the little information you've provided, I'd trash Compressor and download it again from the App Store.
You could share the timeline out to MPEG2 and then import that into iDVD, if you have it, or Toast.
Given an hour or three, someone with better suggestions will soon chime in.

I have had about 9 iOS devices at work do this.
The fix and it will wipe out anything on your iphone is to connect it to your computer and have the latest version on iTunes open. Hold the Power/Sleep and Home button till it blanks out. Keep holding the home button untill it says recovery mode on the screen of the computer and do a restore.

Double tap home button quickly in new row of icons at bottom, tap and hold your Message Icon until the Red Minus Sign appears, tap it to delete from background memory. Then slide all the icons to the right, all the way, see if the Lock Icon is present, if locked, unlock it. See if Message is better, if not, Reset iPhone, hold both home and Power buttons until the iPhone restarts itself, ignore the "slide to power off" let the iPhone restart itself, usually takes about 10 seconds of holding both buttons.
