Step 1: Restore the registry entries associated with error 5.

It is not recommended to manually edit the registry to remove invalid Error 5 cleanup keys unless you are a computer technician. Improperly editing the registry can cause your computer to crash and cause irreparable damage to your operating system. A misplaced comma can even prevent your computer from being completely restarted.

Due to this risk, it is advisable to use a registry cleaner to assist the user. Using a registry cleaner automates the process of searching for invalid registry entries, missing file references (such as those that cause the CCleaner 5 error), and other invalid registry references.

Each scan automatically creates a backup so you can undo any changes with a single click, protecting you from potential damage to your computer. mundobytes.com recommends software to help you solve these problems:

Warning: Unless you are an experienced user, we do NOT recommend manually editing the Windows Registry. Improper use of the Registry Editor can cause serious problems that may require reinstalling your operating system.

Microsoft cannot guarantee that problems caused by the incorrect use of Registry Editor will be resolved. Use it at your own risk.

• Hold down the CTRL key on your keyboard and press ENTER.
• The permissions dialog box will appear.
• Click “Yes”.

Step 3: Remove unnecessary files from your system (temporary files and folders) with a disk cleaner (cleanmgr).

Over time , as you connect to and use your computer, unwanted files accumulate. If these unwanted files are not cleaned regularly, CCleaner may run slowly or display a CCleaner error 5 , possibly due to file conflicts or hard drive overload.

Deleting these temporary files with Disk Cleanup not only eliminates error 5, but also improves computer performance.

Tip: While Disk Cleanup is a great built-in tool, it can't completely clean all temporary files from your computer. Other programs you use regularly, such as Microsoft Office , Firefox, Chrome, Live Messenger , and hundreds of others, cannot be cleaned with Disk Cleanup (this includes some programs from Piriform Ltd).

Other details

Due to the disadvantages of the Windows Disk Cleanup utility (Cleanmgr), it is recommended to use special disk cleanup and privacy software to clean up the entire computer. mundobytes.com we recommend a software to help you clean your temporary files:

Step 4: Update your computer's drivers.

Cleanup Error 5 errors can be caused by corrupted or outdated device drivers. It happens that drivers work one day and suddenly stop working the next day due to various reasons.

The good news is that you can update your device driver to fix Error 5. Finding the right driver for your hardware device can be very difficult, even directly on the websites of Piriform Ltd or other manufacturers.

Even if you are used to manually searching, downloading, and updating drivers, this process can be long and tedious. Installing the wrong driver or an incompatible version of the correct driver can make problems worse.

Due to the time and complexity involved in updating drivers, we recommend using driver update software . Driver update tools ensure that you have the correct versions for your hardware and that your current drivers are backed up before making any changes.

• Click the start button.
• Enter “update” in the search box and press ENTER.
• The dialog box will appear. Windows Update.
• If updates are available, Click Install Updates.

Step 9: Check if the hard drive is damaged («chkdsk /f»)

While most Blue Screen of Death 5 memory errors are caused by problems with the hard drive controller or memory, in some cases BSOD errors can be caused by a faulty hard drive.

Over time, hard drive controller errors can occur due to repeated and unintentional misuse of the computer. Improper shutdowns, programs that force the system to shut down, incomplete or incorrect software installation (e.g. CCleaner), hardware errors, and power failures can corrupt the system file and stored data.

As a result, you may encounter blue screen errors related to cleanup error 5. Microsoft has added a helpful utility called "chkdsk" ("Check Disk") to check for and repair hard drive corruption. If the steps above did not resolve Stop Error 5, you can run "chkdsk" to find the cause of the BSOD and fix it.

To run «chkdsk (Windows XP, Vista, 7, 8, and 10):

• Click the start button.
• Enter “command” in the search box. Do not press the ENTER key yet.
• Hold down the CTRL key on your keyboard and press ENTER.
• The permissions dialog box will appear.
• Click “Yes”.
• A black window appears with a blinking cursor.
• Type «chkdsk /f» and press ENTER.
• «chkdsk» starts checking the hard drive for damage, which can lead to STOP5 errors.

Follow the instructions that appear on the screen.

Full list of «chkdsk» commands. (For advanced users only):

1. /F: Check and clear hard drive errors.
2. /V: Displays the name of each file in each directory when searching the disk.

• FAT/FAT32 disk: Displays the full path and name of each file on the disk.
• Disc NTFS: Display messages when data is deleted.

1. /R: This command detects bad sectors and restores read information (assumes /F).
2. /L: Size (NTFS only): This command changes the log file size to kilobytes after the colon. If no size is specified, the current size is displayed.
3. /X: Forces the specified volume to be unmounted first, if applicable. All open operations on this volume are invalid (assume /F).
4. /I (NTFS only): performs a less than complete check of the hard drive index entries.
5. /C (NTFS only): does not check for loops in the directory structure.
6. /B (NTSF only): re-evaluate failed hard disk clusters (assumes /F).

Step 10: Check if the memory (RAM) is damaged.

Sometimes hardware-related cleanup errors can be caused by corrupted RAM. If your computer restarts at irregular intervals, if you hear beeping codes at startup, or if your computer crashes in any other way (other than the BSOD error 5), it's likely that the memory is corrupted . In fact, around 10% of Windows application crashes are caused by memory corruption.

If you recently installed new memory in your computer, we recommend temporarily removing it to ensure it's not causing the Cleanup Error 5. If this clears the BSOD, it means it's the cause of the problem and the new memory is corrupted or incompatible. In this case, replace the memory modules with new ones.

Other details

If no new memory has been added, the next step is to run a diagnostic test of the computer's existing memory. The memory test analyzes for physical memory defects and recurring errors that can cause the Blue Screen of Death error.

Although recent versions of Windows include the Windows Memory Diagnostic tool, it is recommended to use Memtest86 . Memtest86 is a BIOS-based memory testing program, unlike other testing programs that must run under Windows.

Its advantage is that it can search for CCleaner Error 5 errors in the entire memory, while other programs cannot analyze the memory area occupied by the program itself, the operating system, and other running programs.

Tutorial

Here's how to run Memtest86 to check for memory corruption caused by CCleaner Error 5:

• Take a memory USB unused and connect it to your computer.
• Download the USB image from MemTest86 for Windows.
• Right click on the image file and select Extract here. Extract the folder with the files to an easily accessible location (for example, the desktop).
• In the extracted folder, run the imageUSB utility and select the USB memory connected to boot it. WARNING: This will erase all data on the USB flash drive.
• Memtest86 will not install on USB stick and you will be able to search for possible sources of deletion error 5.
• Once the USB flash drive is installed, restart your computer.
• Memtest86 will start checking for memory corruption.

Follow the instructions that appear on the screen.

If the previous steps haven't worked and Memtest86 has detected memory corruption, the CCleaner Blue Screen of Death (BSOD) Error 5 may be due to this corruption. In these cases, replacing the corrupted memory should resolve BSOD 5.

Step 11: Perform a fresh installation of Windows.

Note: Reinstalling Windows is a lengthy and time-consuming task. To avoid data loss, be sure to back up all important documents, pictures, installation programs, and other personal data before starting the process. If you haven't already backed up your data, do so immediately to protect it from irreversible loss.

Last details

This step is your last chance to fix deletion error 5: Reinstalling Windows will erase all the contents of your hard drive and allow you to start working with the new system. Additionally, reinstalling Windows removes any "junk" files that may have accumulated over time.

If the 5 errors persist even after a fresh installation of Windows, the runtime errors problem must be hardware related. In this case, it may be necessary to replace the hardware causing the error 5.
