How to fix error 0xc19001e1 in Windows 10?

The main cause of error code 0xc19001e1 in Windows 10 is a problematic Microsoft update. However, it may also turn out that there is not enough space on the system logical drive. It is very important to check before each system upgrade if there is free space on the disk where the operating system is installed. If it is not enough (only a couple of gigabytes), a message with error 0xc19001e1 will appear. Almost always, the size of the update in the spec sheet is smaller than it actually is. All due to the fact that when downloading the files are compressed, and then unpacked and grow in size.

Cleaning up disk space

There are many effective ways to clean up your drive, and right now we suggest using Windows Native Disk Cleanup. The method itself may not work, it is also worth removing unnecessary programs and restarting the update services. Many users wrote that it helped them.

What to do:

1. Right-click on the C drive (or another one where Windows is installed) and go to “Properties”.
2. On the main page, click on the “Disk Cleanup” button.
3. After a short time of collecting data, we check that the boxes next to “Clean up Windows Update”, “Temporary Internet files” and “Temporary files” are checked. Then click on the “Ok” button.
4. Once the cleaning is complete, right-click on “This Computer” and select “Manage”.
5. We select the item “Services and Applications”, and then in the right pane – “Services”.
6. Disable the Windows Installer service through its properties and restart it.
7. We carry out the same action with the Windows Update service.
8. We reboot the computer and update the operating system.

Resetting Windows Update settings

The essence of the method is to reset the Windows Update settings, because the tool itself can freeze, get damaged, etc. Due to its failure, very often an error with the code 0xc19001e1 appears, and many others too.

Step by step guide:

1. We open the command line (be sure to give it administrator rights).
2. Run the following commands one by one, be sure to in the same order:
   1. SC config wuauserv start = auto
   2. SC config bits start = auto
   3. SC config cryptsvc start = auto
   4. SC config trustedinstaller start = auto
3. We reboot the computer and check the result.

Most often this is enough, but if there is still no improvement, we suggest the next cycle of console commands (entered one by one, after each press Enter). We use them to clean temporary files, stop services and start them again.

• net stop wuauserv
• net stop cryptSvc
• net stop bits
• net stop msiserver
• Ren C: \ Windows \ SoftwareDistribution SoftwareDistribution.old
• Ren C: \ Windows \ System32 \ catroot2 Catroot2.old
• net start wuauserv
• net start cryptSvc
• net start bits
• net start msiserver

After restarting the system, there should be an improvement, and the error 0xc19001e1 during the update should recede.
