How To Fix 0x8007045d i/o ? >> Download The Fix Here <<

For some reason I've had quite afew emails from readers over the last two weeks about their problems with 0x8007045d i/o, so if you've arrived here because you're getting the same error, then not to worry - you're not alone.

It is strange however, that so many people are having the same issue all of a sudden, so my best guess is that the Windows automatic updateKB 979683 or KB 978601 is to blame. (It could also be due to other factors, but the fix remains the same.)

After speaking to afew of you that have successfully fixed this fault, it seems that there's more than one way to go about the repair and that one way works for some of you whilst another method is needed for the rest, so I've combined them both here. You won't know which group you're in until the end, but not to worry - it won't take long.

So What's The Solution?

As my more loyal readers may know, I'm good friends with Mike at TechGuy.org and we were having a chat about this issue recently. Anyway, we came up with the following 3 step approach that should work for most of you;

Step 1:

First, we'll start with the big gun; PC Cleaner Pro. This program specializes in Windows repair. It fixes, Internet Explorer errors, ActiveX errors, Javascript and scripting errors, C++ errors, EXE/ DLL/ OCX/ INF/ VXD errors, slow sluggish behavior and tons more errors. Not to mention, fine tune your PC for maximum performance.

Here's how to use it.

Click here to download PC_Cleaner_Pro.exe

  • Save PC_Cleaner_Pro.exe to your desktop.
  • Double click on the PC_Cleaner_Pro.exe icon on your desktop.
  • By default it will install to C:\Program Files\PC Cleaners\
  • Click on Install and follow the on screen instructions.
  • It will create a PC Cleaners icon on the desktop.
  • Once installed, launch PC Cleaner; it will automatically start a scan.
  • When it's finished, click on Fix All. (Register if required.)

Step 2:

For some reason still unknown to us (like I said, this appears to be a new problem) over two-thirds that successfully repaired this error said they needed toReimage their machine. Not doing this seems to make the error come back again after a restart.

The Reimage program specializes in Windows repair. It scans and diagnoses, then repairs, your damaged PC and not only fixes your Windows operating system, but also reverses the damage already done with its full database of replacement files.

Step 3:

Now we can finally run Windows Update.

We need to make sure that Windows is up to date and has all the latest patches and updates installed. To do this we start by opening Windows Update. You can either search for 'Windows Update' in the search box at the bottom of the Start Menu or you can visithttp://windowsupdate.microsoft.com and it will automatically load it for you.

That's it, the problem should be fixed.

A Note About Your Machine

Now, as to what's causing the error on your machine, there's no way for me to know. However, using the tools above you should be able to quickly see if it can fix the problem and take appropriate action.
