Manually editing the Windows registry to remove invalid Windows keys is not recommended unless you are PC service professional. Incorrectly editing your registry can stop your PC from functioning and create irreversible damage to your operating system. In fact, one misplaced comma can prevent your PC from booting entirely!

Because of this risk, we recommend using a registry cleaner to assist with this process. Using a registry cleaner automates the process of finding invalid registry entries, missing file references (like the one causing your Windows error), and broken links within the registry. A backup is automatically created before each scan, with the ability to undo any changes in a single click, protecting you against the possibility of PC damage.

As a Microsoft Silver Partner, we provide software that can assist you in removing these issues:

There is a chance that your Windows error could be related to a malware infection on your PC. These malicious intruders can damage, corrupt, or even delete DLL-related files. Furthermore, there's a possibility that the win32.dll error you are experiencing is related to a component of the malicious program itself.

Over time, your computer accumulates junk files from normal web surfing and computer use. If this junk isn't occasionally cleaned out, it can cause Windows to respond slowly or provides an Windows error, possibly due to file conflicts or an overloaded hard drive. Cleaning up these temporary files with Disk Cleanup might not only solve your win32.dll error, but can also dramatically speed up the performance of your PC.

Because of the shortcomings of the Windows Disk Cleanup (cleanmgr) tool, we highly recommend using a specialized hard drive cleanup / privacy protection software to clean up your entire computer.

As a Microsoft Silver Partner, we provide software that can assist you in cleaning up your temporary files:

• WinSweeper Privacy Cleaner [Download]

How to run Disk Cleanup (cleanmgr) (Windows XP, Vista, 7, 8, and 10):

1. Click the Start button.
2. Type "command" in the search box... DO NOT hit ENTER yet!
3. While holding CTRL-Shift on your keyboard, hit ENTER.
4. You will be prompted with a permission dialog box.
5. Click Yes.
6. A black box will open with a blinking cursor.
7. Type "cleanmgr" and hit ENTER.
8. Disk Cleanup will begin calculating how much occupied disk space you can reclaim.
9. The Disk Cleanup dialog box will appear with series of checkboxes you can select. In most cases, the "Temporary Files" category will occupy the most disk space.

Windows errors can be related to corrupt or outdated device drivers. Drivers can work one day, and suddenly stop working the next day, for a variety of reasons. The good news is that you can often update the device driver to fix the Error win32.dll problem.

Finding the exact driver for your Error win32.dll-related hardware device can be extremely difficult, even directly on the Microsoft or related manufacturer's website. Even if you are experienced at finding, downloading, and manually updating drivers, the process can still be very time consuming and extremely irritating. Installing the wrong driver, or simply an incompatible version of the right driver, can make your problems even worse.

Because of the time and complexity involved in updating drivers, we highly recommend using a driver update software. A driver update tool ensures that you have correct driver versions for your hardware, and also creates a backup of your current drivers before making any changes. Maintaining a driver backup provides you with the security of knowing that you can rollback any driver to a previous version (if necessary).

As a Microsoft Silver Partner, we provide software that can assist you in updating these drivers:

Microsoft is constantly updating and improving Windows system files that could be associated with Windows. Sometimes resolving your DLL problems may be as simple as updating Windows with the latest Service Pack or other patch that Microsoft releases on an ongoing basis.

To check for Windows Updates (Windows XP, Vista, 7, 8, and 10):

1. Click the Start button.
2. Type "update" into the search box and hit ENTER.

While most storage-related, win32.dll blue screen errors are caused by problems with your hard disk drivers or storage controllers, in some cases these BSODs can be attributed to hard drive corruption.

Over time, your PC can develop errors on the hard disk drive due to repeated, unintended misuse. Improper shut downs, “hard closing” programs, corrupt or incomplete installation of software (eg. Windows), Microsoft hardware failure, and power outages can corrupt your file system and stored data. As a result, you may experience blue screen errors associated with Windows.

Microsoft has included a convenient utility called “chkdsk” (“Check Disk”) to scan and repair hard disk corruption. If the previous troubleshooting steps did not resolve your win32.dll STOP error, running “chkdsk” may uncover and repair the cause of your BSOD.

How to run “chkdsk” (Windows XP, Vista, 7, 8, and 10):

1. Click the Start button.
2. Type "command" in the search box... DO NOT hit ENTER yet!
3. While holding CTRL-Shift on your keyboard, hit ENTER.
4. You will be prompted with a permission dialog box.
5. Click Yes.
6. A black box will open with a blinking cursor.
7. Type "chkdsk /f" and hit ENTER.
8. "chkdsk" will begin scanning for hard disk corruption that could be causing win32.dll STOP errors.
9. Follow the on-screen commands.

Sometimes hardware-related Windows blue screen errors can be due to memory (RAM) corruption. If you are experiencing random computer reboots, receiving “beep” codes on startup, or other computer crashes (in addition to win32.dll BSOD errors), it is likely that your memory could be corrupt. In fact, nearly 10% of application crashes in Windows are due to memory corruption.

If you have just added new memory to the computer, we recommend temporarily removing it to make sure it is not the cause of your Windows error. If this action resolves your BSOD, this will be the source of your problem, and therefore your new memory is either incompatible or bad. If that is the case, you will then need to replace your new memory modules.

If you haven’t added any new memory, the next step is to perform a diagnostic test on your computer’s existing memory. A memory test will scan for hard memory failures and intermittent errors, either of which could be causing your win32.dll blue screen of death.

Although later versions of Windows include the Windows Memory Diagnostic Tool, I highly recommend using Memtest86 instead. Memtest86 is a BIOS-based memory testing software, unlike other testing programs that must run within Windows. The benefit is that it allows you to test ALL of your memory for Windows errors, while other programs cannot test the section of memory occupied by the software itself, the operating system, and any other running programs.

How to run Memtest86 to scan for memory corruption causing win32.dll STOP errors:

1. Grab an unused USB flash drive and connect it to your PC.
2. Download the Windows MemTest86 USB image.
3. Right click on the image file, and select the "Extract to Here" option. Extract the file folder anywhere you can get to easily (eg. your Desktop).
4. Inside the extracted folder, run the included imageUSB tool, and choose your plugged in USB drive to turn into a bootable drive. CAUTION: this action will erase all data on the USB drive.
5. Memtest86 will now be installed on your USB and you are ready to test for the possible source of Windows errors.
6. Restart your PC with the USB drive installed.
7. Memtest86 will begin testing for memory corruption.
8. Follow the on-screen commands.

If all of the above steps were unsuccessful, and Memtest86 finds memory corruption, it highly likely that your Windows blue screen error is due to bad memory. If this is the case, you will need to replace the bad memory to resolve your win32.dll BSODs.

For additional help, Corsair has a great video tutorial on how to run Memtest86:

This step is your final option in trying to resolve your Windows issue. Reinstalling Windows will erase everything from your hard drive, allowing you to start again with a fresh system. Furthermore, a clean install of Windows will also quickly clean out any and all "junk" that has accumulated over the normal usage of your computer.
