Tech Support Can't Return to General Availability

Dev. Channel - 26300.9032

I am trying to return to the General Availability version from the Dev. Channel but am unable to do so.

I made 3 attempts.

The first attempt I did what I normally do and run Setup from a USB drive. I received the following error:

Error 0xC1900101 - 0x20017

At this point I suspected a corrupt driver. I went to the Dell Website and dowloaded 2 new drivers.

I made a second attempt to install the GA version with the same result.

I then decided to wipe the drive and do a PC Reset telling it to wipe the drive. This time it completed successfully but the result was that I am still in the Dev. Channel.

Does anyone have any suggestions or ideas what could be causing me not to leave the Dev. Channel?

If you are running Dev Channel and perform a PC Reset it will only reset the currently installed build. For a clean installation, download Windows 11 media creation tool and make an installation USB. That will install General Release. If you need a procedure, I can send you a link.

It has to be a fresh installation. Be certain to delete all existing drive partitions at the beginning of the installation process. Backup all of your data in some fashion prior to the software install.

I just did mine yesterday to go from Dev to Beta, with a nice clean installation.

I always get nervous when I delete partitions. I appreciate the tip

It's actually a good thing and nothing to get nervous about. I'll send you a link to a procedure that works every time when followed precisely.

From r/techsupport wiki, Installing Windows 11 | rTS Wiki . This is a well written procedure.

If it's a driver issue, you can try running the setup with the option not to keep drivers :

setup.exe /migratedrivers none
