As many factors emerge after in-depth digging, only to realize that they have been wrong all along.

2: Clean up old installation files & previous update files

Microsoft cleverly creates additional installation files and system files, which end up causing a menace later down the line. Consumers who have upgraded from build version 1703 to build version 1903 might suffer from system file clash. Administrators bear the responsibility to wipe out the old remnants of the previous installation.

Step 1: We suggest using the free edition of CCleaner to wipe out Cache, Old installation files, Registry keys, and junk files.

Step 2: Take a quick look at the snapshot below, and select every given option. However, keep “Wipe Free Space” out of the cleaning equation because it consumes hours of energy.


Note: Selecting multiple options for cleaning erases personal data such as browsing history, network password, etc.

Step 3: Click on “Run Cleaner” and let the cleaning mechanism continue until the task is finished.

Step 4: You can view the detailed report on what files erased during the process.

System file corruption is not a stranger to previous versions and latest build versions. Millions of Windows machine felt the ease of breath by getting rid of Windows Update Cache or Software Distribution folder. Microsoft servers replace the old files with the corrupted ones, and they tend to get affected by the existing files. As the old saying goes, “one bad fish can ruin an entire pond” and that is what is going on with your copy of Windows machine.

4: Turn off Antivirus Program

Online security programs such as Avast, Bitdefender, Kaspersky, McAfee, others suffer from misrecognizing “false positive” threats. Unfortunately, Microsoft shipping unsigned drivers, system files, and core element files directly from servers, which antivirus solutions strictly interrupts the connection and stands against it.

Again, Microsoft does spread system files that are not signed and they don’t even provide description on what the updates do. I must say that Microsoft should take responsibility for the unknown services and explain what they are about.

I hate to say it, but you have to turn off Antivirus program temporarily.

Remember, any edition of Antivirus solution can interfere in the updating process. Be it a free edition, or premium edition of an online security program.

Brace yourself, and back up the files immediately because it’s going to be a long ride. Windows OS tend to operate slightly differently when compared to other mashed up desktop environments. Millions of machines do not hold up against file system corruption and they disperse into irrecoverable state. The installation of the latest build version of Windows offers fresh copy of system files and improved features.

Step 1: Click on the official Microsoft link. Download media file creator and then follow the MS instructions.
