Windows 11 Cumulative Update not downloading and installing.

Hi SamMaverick.

I'm David, and I'm happy to help you.

Run the Windows Update Troubleshooter.

https://support.microsoft.com/en-us/windows/win...

If it persists, rename the software distribution folders as instructed below:

1. Open Start and type cmd, right-click on "Command Prompt", and select "Run as administrator".
2. Run the following commands at the Command Prompt one at a time:

net stop bits

net stop wuauserv

net stop cryptsvc

ren %systemroot%\softwaredistribution softwaredistribution.bak

ren %systemroot%\system32\catroot2 catroot2.bak

net start bits

net start wuauserv

net start cryptsvc

3. After all these commands are completed, close the Command Prompt window, restart your computer, and then try to update Windows.

If it persists, use the system file checker to repair possible corrupted or missing system files.

1. Open Start and type cmd, right-click on "Command Prompt", and select "Run as administrator".
2. Run the following commands at the Command Prompt one at a time:

dism.exe /online /cleanup-image /scanhealth

dism.exe /online /cleanup-image /restorehealth

dism.exe /online /cleanup-image /startcomponentcleanup

sfc /scannow

3. Then restart your PC and see if you can update.

If it persists, download and install the update that is having problems manually.

I'm having the same problem. Nothing has come close to resolve it and WINDOWS 11 team ... NOT A WORD! WE NEED HELP!!

My laptop has gove VERY SLOW!! and crashing programs. Anyone???

LizBOCE, I am sorry you are experiencing problems like I am. After several failed attempts to solving this WINDOWS problem (I say Windows because the problem originated with a Microsoft CUMULATIVE UPDATE download); Microsoft recommended I download a new Windows 11 from their site onto a disc, USB or other drive and do a "mount" install. After 3 attempts to do so, I called Microsoft who then informed me they were having problems with their site and to "try back sometime later". When I asked if they could call me back, text or email me when their site was up, they simply said "we don't do that". Can make a person feel like they don't care that the problem was caused by them and their solution does not work.

My most recent successful "Cumulative" Update was on April 12th is = 2022-04 Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 11 for x64 (KB5012121).

There have been other kinds of successful updates sine that time (including yesterday).

It is only the two most recent Cumulative Updates that will not download and install. They are:

1. 2022-04 Cumulative Update for Windows 11 for x64-based Systems (KB5012643) (42)
2. 2022-04 Cumulative Update for Windows 11 for x64-based Systems (KB5012592)
