Caution: Unless you an advanced PC user, we DO NOT recommend editing the Windows registry manually.
Using Registry Editor incorrectly can cause serious problems that may require you to reinstall Windows.
Furthermore, there's a possibility that the 4000 error you are experiencing is related to a component of the malicious program itself.
Tip: If you do not already have a malware protection program installed, we highly recommend using Emsisoft Anti-Malware (download here).
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!
Cleaning up these temporary files with Disk Cleanup might not only solve your 4000 error, but can also dramatically speed up the performance of your PC.
These 4000 error messages can appear during program installation, while a Apple Inc.-related software program (eg.
i Tunes) is running, during Windows startup or shutdown, or even during the installation of the Windows operating system.
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 4000 problem.
Running Win Sweeper once per day (using automatic scanning) will ensure that your computer is always clean, running fast, and free of 4000 errors related to temporary files.
