If you are trying to update or upgrade your Windows 10 computer using the Windows Update and suddenly an “Error 0x800f0900” appears, then you’ve come to the right place as this post will help you resolve this Windows Update issue. When you encounter this error, you will see the following error message on your screen:
“There were problems installing some updates, but we’ll try again later. If you keep seeing this and you want to search the web or contact support for information, this may help:
2018-03 Cumulative Update for Windows 10 Version 1709 for x64-based Systems (KB4088776) – Error 0X800F0900”
This kind of Windows Update error is most likely caused by some corrupted files in the system. It is also possible that the Windows Database might have become corrupted as well. So if you are currently experiencing this problem, refer to the options given below and see which one of them works best for you.
Running the DISM Tool helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.
After you run this tool, a log file is created at C:WindowsLogsCBSCBS.log. On the other hand, if the Windows Update client is already broken, you will be prompted to use a running Windows installation as the repair source or use a Windows side-by-side folder from a network share, as the source of the files. Although the chances of this happening are less, if it turns out to be the case, you need to run an advanced command in the DISM tool to repair a broken Windows Update. Just repeat the process above but use the following command instead:
DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess
The SFC scan or System File Checker is a built-in command utility in Windows that helps in restoring corrupted files as well as missing files that cause several issues in the computer like the Windows Update Error 0x800f0900. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.
The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:
Running the built-in Windows Update troubleshooter could also help you resolve the Windows Update error 0x80073712. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.
You can also try to perform a System Restore as it can also help you fix the Windows Update Error 0x800f0900. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.
You have to stop a couple of services such as BITS, Cryptographic, MSI Installer, and Windows Update Services. And to do that, you need to flush the contents in the SoftwareDistribution folder. The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. Aside from that, it also contains all the Windows Update History files and once you delete them, you will most likely lose the Update history. As a result, the next time you run the Windows Update, it may result in a longer detection time.
net stop wuauserv
net start cryptSvc
net start bits
net start msiserver
After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:
net start wuauserv
net start cryptSvc
net start bits
net start msiserver

Razer is a well-known brand among PC gamers and users, it started as a peripheral manufacturer focused on keyboards and mouse but after years passed Razer expanded its inventory offerings. It soon started offering headphones and lately has branched into wider product lines like gaming chairs and protection masks.
It is not a big surprise that Razer is expanding into other branches of the PC industry. This time, however, it has revealed not one but three new hardware for your PC. Case fans, all in one liquid cooler and power supply.

It is a modular power supply ranging from 750W to 1200W with the additional option of Titanium rated one with an impressive 1600W of power. Power supply will start shipping in early 2022 and at the time of writing this article no price range has been released.
Hanbo liquid cooler will feature an optimized intake design so it can ensure greater heat transfer and fluid dynamic for improved reliability and silent operation. Radiator comes in 240mm size with two fans and a larger one of 360mm with three fans. The pump will be able to rotate in any direction of full 360 degrees so it can fit in any case. Hanbo will be released in November this year but no pricing has been released so far.
Kunai fans will boast high static pressure performance with lowered noise. They will go as far as 2200rpm for the 120mm version where the 140mm version will go up to 1600rpm. They will come with addressable LEDs and up to eight fans will be able to be connected to Razer’s PWM fan controller that will come with a magnet at the back for easy attachment to any steel part of PC casing.
PWM will use Razer’s Synapse software to customize pulse width modulation in order to improve airflow and noise. PWM will be priced at $49.99 in the Razer Store and it is available for preorder. Fans are priced at $44.99 for one 120mm or $129.99 for a three-pack of 120mm. One 140mm will go for $49.99 and a three-pack will be $129.99.
