2. Scan For Viruses

The virus in the system also plays a major role in throwing this error. These viruses tend to infect the core program files that Windows requires to run. Also, this causes the files to become unreadable. As a result, Windows will be unable to process the commands we need, leading to it showing the error.

So we suggest using any virus scanner to clean the Virus.

3. Clean Out The Registry

The registry is a central database that stores settings and information for the system. But this registry also can get corrupted. As a result, the system might slow down.

To fix this, we use 'registry cleaner' to scan through the registry and repair any of the damaged parts of it.
