Hi for BYOL Workspaces Pools, is there an AWS version of the Citrix Optimizer tool?

No

No. But speaking strictly with the goal of optimizing a Windows image for non-persistent use in mind, I typically point people towards the VMware OS Optimization Tool because it's very robust and it's not specific to Horizon. Great for making your own repeatable recipe, and it has rollback options. You could still use the Citrix tool also. Use a test WorkSpaces to experiment--as with any of these tools that mess with image optimization, there's always a risk of breaking something. I usually choose to spend some time going through the list of optimizations and pick them one by one.

Thanks both. We'll do some testing.

You really can't go wrong with the usual optimizations, but to be frank - most customers don't do any of that
