To free up disk space, first open the “Add or Remove Program” window from the “Control Panel”, browse through the “Currently installed Programs” list and remove all applications and utilities you no longer require.
After you have eliminated junk files from your system, run Disk Defragmenter from System Tools to defrag the hard drive to make the files on the disk contiguous. These tasks not only help you in fixing many system errors, but also boost the PC’s performance.
Step 2: Detect and remove malware infections
Many system errors are caused by virus and spyware infections. These files usually infiltrate your system through unsolicited email attachments, dubious websites, infected external media, and open network connections.
Malware programs add several malicious files to your hard disk and a large number of erroneous and incorrect entries in the registry. Once they infect your PC, malware programs cause dramatic deterioration in your PC’s performance and also generate several system errors. At times, these programs may also damage your PC beyond repair.
To fix problems related to malware programs you need tools like antivirus and antispyware. Purchase reliable antivirus and antispyware tools, update them regularly with the latest definitions, and run regular full system scans to keep your PC free from errors caused by malware programs.
Step 3: Update your PC with latest service packs, patches and hotfixes
Many errors are generated due to outdated system and program files. To fix and prevent these errors, you must ensure that your Windows operating system, applications installed on it, and device drivers are updated with the latest service packs, patches and hotfixes released by their manufacturers.
When you update your system, you not only prevent several system errors, but also enhance the security of your system because many software updates are released to patch up security vulnerabilities in the software.
Step 4: Scan and repair registry errors
The registry is the heart of your Windows system because it comprises information that is required by all software and hardware installed on your PC. When your PC is operational, a large number of entries are added, removed and modified in the registry. In the process, a large number of unwanted, outdated, and incorrect registry keys get accumulated in the registry. This unwanted information causes the registry to bloat and may eventually corrupt and fragment it. A damaged registry becomes unstable and starts generating errors on your system.
To get rid of this unwanted registry data and to perform registry fixes, you need a registry cleaner tool. These tools are user-friendly and include features to perform registry maintenance by detecting and fixing registry errors, defragging the registry, and making system backups.
