how to uninstall new "Windows Backup" bloat app?

Thanks for the testing @garlin
I've updated the script and will attach it here.
However for me, it seems very hit and miss if it works now on my daily use PC! On my test VM it's great and works every time.

Remove Windows Backup App. (Copy in Terminal or Powershell)

$remove_appx = @("Client.CBS"); $provisioned = get-appxprovisionedpackage -online; $appxpackage = get-appxpackage -allusers; $eol = @()
$store = 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Appx\AppxAllUserStore'
$users = @('S-1-5-18'); if (test-path $store) {$users += $((dir $store -ea 0 |where {$_ -like '*S-1-5-21*'}).PSChildName)}
foreach ($choice in $remove_appx) { if ('' -eq $choice.Trim()) {continue}
foreach ($appx in $($provisioned |where {$_.PackageName -like "*$choice*"})) {
$next = !1; foreach ($no in $skip) {if ($appx.PackageName -like "*$no*") {$next = !0}} ; if ($next) {continue}
$PackageName = $appx.PackageName; $PackageFamilyName = ($appxpackage |where {$_.Name -eq $appx.DisplayName}).PackageFamilyName
ni "$store\Deprovisioned\$PackageFamilyName" -force >''; $PackageFamilyName
foreach ($sid in $users) {ni "$store\EndOfLife\$sid\$PackageName" -force >''} ; $eol += $PackageName
dism /online /set-nonremovableapppolicy /packagefamily:$PackageFamilyName /nonremovable:0 >''
remove-appxprovisionedpackage -packagename $PackageName -online -allusers >''
}
foreach ($appx in $($appxpackage |where {$_.PackageFullName -like "*$choice*"})) {
$next = !1; foreach ($no in $skip) {if ($appx.PackageFullName -like "*$no*") {$next = !0}} ; if ($next) {continue}
$PackageFullName = $appx.PackageFullName;
ni "$store\Deprovisioned\$appx.PackageFamilyName" -force >''; $PackageFullName
foreach ($sid in $users) {ni "$store\EndOfLife\$sid\$PackageFullName" -force >''} ; $eol += $PackageFullName
dism /online /set-nonremovableapppolicy /packagefamily:$PackageFamilyName /nonremovable:0 >''
remove-appxpackage -package $PackageFullName -allusers >''
}
}

There are code tags for that.

It's been repeated many times, removing Client.CBS will break your desktop. Some users don't care about the broken features.

AveYo's code snippet is hideously overkill and can be simplified when removing one Appx package:

$PackageFamilyName = $appx.PackageFamilyName
$PackageFullName = $appx.PackageFullName; $PackageFullName

ni "$store\Deprovisioned\$PackageFamilyName" -force >''
dism /online /set-nonremovableapppolicy /packagefamily:$PackageFamilyName /nonremovable:0 >''

$store = 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Appx\AppxAllUserStore'
$users = @('S-1-5-18')
$users += $((dir $store -ea 0 |where {$_ -like '*S-1-5-21*'}).PSChildName)

foreach ($sid in $users) { ni "$store\EndOfLife\$sid\$PackageFullName" -force >'' }
remove-appxpackage -package $PackageFullName -allusers >''

Herein lies the risk of using amateur scripts without extensive testing and a good understanding of what the script does.

A decent script should be properly annotated with comments saying what next step does.

More importantly, it is funny how such script writers never advise users to make full system image backups or test in virtual machines etc.
