How to Reconfigure Creators Update Recovery Partition?

Thanks to all for your help.

I just updated another PC to the CU and that just replaced the previous recovery partition at the end of the drive with a larger 900MB+ recovery partition.

I modified the partitions on my laptop as mentioned in post 1. MiniTool Partition Wizard gave an error trying to extend Drive C: whilst in Windows so I booted to KYHI's recovery disk and used Partition Wizard from there which worked. Does Partition Wizard often give errors when you try to reconfigure the C: drive?

I used the commands recommended by lx07 post 2 to reconfigure Win RE on my laptop. I got an error saying that drive T could not be accessed but reagentc /info reports the recovery environment is correctly configured and I checked it works. Go figure.

It should say it can't do it and ask you to reboot. It then makes changes to C before Windows starts as it can't move C while it is in use - same as running it from PE really. I've only used it to do that once (to swap C and the partition I had for OSX) though. Normally I create partitions manually and reinstall as moving partitions is very slow.

Don't know about that. Perhaps the letter wasn't assigned. Still if it works there is nothing to worry about.
