You can try to run Reinstall: Go to Settings / System / Recovery and click 'Reinstall now'.
That will reinstall your current Windows without deleting your datafiles or apps.

Hi All
On May 3rd this year Windows tech support asked me to download and install an ISO to fix problems caused by the 0x80240067 error- (can't download updates from Microsoft Store).
This worked but in recent months I've been having crashes with my main Recording Program ( Cubase Pro). On investigation their Tech Support flagged up that my ISO installation, being a Beta Insiders Version could not be supported as it was causing the problems.
Not being a Windows expert or Insider I don't know how to proceed....
Can anyone shed light on W11 build 26100.1- 10.0.26100.1 and whether I should look at ways to change it...?
Many thanks for any help, joe read

2025-08-31T13:31:41.95+00:00 Build 26100.4946 is released on August patch Tuesday and you are one optional build behind curent build 26100.5074.
If you are in Release Preview channel and your device meet Windows 11 requirements you should have get 25H2 build 26200.5074. Are you in Release preview channel and is your system trying to get that build? Do you get any error message/number?
MS Insider team will be releasing ISO of 25H2 build 26200.5074 next week. With that you can try to do in-place update.
Windows 11 24H2 is based on build 26100.1 which is shown by crash dump.

Following your steps my build is- 26100, 4946.
Do you know why Crash dumps show my build as 10.0.26100.1...?
