continual known folder error 0x8007002

Well Ethel this just about rules out the hard drive in it's physical properties at least.

Now if you Google "UAC File Virtualization event 2007" there are stack of hits but most are account based which to me doesn't make sense your account shouldn't be causing this grief.

I am beginning to think that a clean install may be the answer but lets just chase down some other thoughts first.
Look sorry for the double post but my mobile broadband has been dropping in and out all day and I am just about to go offline for a while soon so don't think I have gone anywhere ok?

Just a thought Ethel before I go offline try doing some of the tweaks in this tutorial - I use this on all my machines - it does mean you have to make do without transparency but I think it is a pointless thing anyway

Optimize Windows 7

I have a few ideas going on but try these first just take your time to run through the tweaks.

Hello Ethel yes am thinking of NBN myself now but back to the problem look if you want to try different accounts see this User Account - Create if you get into strife post in that tutorial Brink can sort anything out but I would make sure that I kept myself as the only user with Admin account rights

Ok Ethel and it didn't hit me until this morning your issue actually happens on this my main desktop - how I missed this is well probably old age.

Now I also have that lag between power on the Asus splash and the the Windows starting up.

Now it might be coincidence but the machine had been running very erratically for some time and the worst problem was the BIOS losing it's settings for example the boot order amongst other little annoying things. I had a thread going right up to just recently and was reseating cards and sticks and heave knows what and then Indianatone suggested renewing the CMOS BIOS battery.
Now this seemed a little too simple for me at the time but I did it and found the battery had run down to 1.02v when it should be at least 3v or very close. Flipped the new battery in and bongo the BIOS settled down and the machine although it still has the lag issue is working as good as it used to - it has a i5K CPU and 2400Mhz RAM and I had been overclocing the CPU and RAM and so irt was something as simple as that battery.
The battery was about four years old if my memory is correct and although one should expect a life of around 5- 6 years (or I have sen them much olde with a decent charge) for the CMOS battery maybe it was a poorly made one or had been in the board for some time before I bought it.

If you ant to try that approach it is quite simple to as long as you remember it will return the BIOS settings to default. The battery is a CR 30232 and costs around $3 but if you do want to try that please make sure you get a really well known brand of battery and not some el cheapo one from those cheap dollar shops - Eveready or Duracell or Energizer (which might EverReady) be would be good bets and get one that states it is long life one - a lithium based one would be the very best.

Sorry but did I say your machine was a laptop ? if I did I don't know what OI was thinking about.

Changing the battery is easy - you just unplug the mains power supply and hold down the power on button for about a minute - make sure you touch the case to ground any static electricity on you - expose the board by lying the case on it's side and remove the side panel almost always the left hand side as you view the machine from the front - have yet to see one that isn't - there should be screws at the back on the side you just remove them and the side panel will come away/ slide backwards off it's mountings and you may have to take out the GPU but I think you are using the onboard (the chip) graphics.
Now you will see a silver coin sized battery on the board I will send a pic and all you need to do is prise the side tag away and the battery should flip up and you remove it. Leave the machine for about 5 minutes and then just push in the new battery it feels like it is clicking into place MAKING SURE THE POSITIVE SIDE IS UPPERMOST that side is marked with a small plus mark . But like I said you will have to set the BIOS again - for ease set it to default settings until we can work out what you can set
