Ive just carried out a fresh install of Win 11. Ive tried every option I can find on the net but the Ultimate performance plan just will not appear. Also, my previews partition drives were deleted during the install and they were labeled D and E. The new install does not show these letters at all ie they do not appear in the available letters list. Is there anything further I can do to fix these two issue? It is a brand new install after all. Cheers.

Sorry, but I need some context. What do you mean by āpreviews partition drivesā?
I have a 2 tb drive on my Surface Pro 9 and I partitioned it into three partitions two of which had Windows installs and one was for data.
Internal drive? Did you, by any chance, delete all partitions during reinstall? Then youāve effectively wiped the whole drive and you have lost all that data. There are recovery tools for this, but most of these are payed and without any guarantee. 
Ughā¦ Iām getting ready to do the Windows 11 āupgradeā this weekend and I have Lenovo Thinkpad.
Does the upgrade reset the power plan to āBalancedā and it is not possible to change it to āHighā or āUltimateā performance without executing Frankās Powershell script under Admin privileges?
If so, Iāll add this to my post upgrade steps. It sounds like the ultimate plan will be retained after applying it?
All this is great, but quite confusing to me. Is there a way to condense it a set of simple instructions?
@bigalminal did a reinstall. Thatās rather different than a Windows 10 to Windows 11 upgrade (from within the os). I have done 10 to 11 upgrades several times and didnāt loose any fil es or settings.
But donāt forget to deactivate licenses before upgrading. For example GP, Plugin Alliance, etc. (But that already has your attention, I saw.)
With regards to powerplans: these are rather tied up to the system, so I wouldnāt expect that these will survive. With powercfg.exe you can however export the current powerplan which you can import and activate after the upgrade.
My Surface Pro 9 had Win 11 when I bought it. I upgraded the SSD to 2 Tb, then divided the space into 3 partitions - two with Windows (one for editing and one for gigging). The third partition was for data where I store all the rack spaces and gig files. This is backed up on to an external SSD. The only reason I reinstalled Windows was because the usb connection between iPad and PC stopped working. I use Ethernet for the connection. I spent a whole day trying to get the usb connection working to no avail. So I thought a reinstall was the best solution. Others wonāt agree.
But during this reinstall, did you remove partitions? Because that would explain why D: and E: have disappeared.
btw: in diskmanager you can see which partitions are actually present. It could be the case that the partitions and volumes are still there, just without a drive letter assigned (which you can correct by right clicking a volume and choosing āchange drive letterā)
Iāve heard some troubling reports that new Windows 11 installs enable Secure Boot and Bit Locker by default and the later wiping out partitions without warning to encrypt the entire drive.
Iāve not done a clean Windows 11 install but have upgraded about 5 Windows 10 machines (bypassing the CPU and TPM 2.0 restrictions) without any problems.
I was not able to opt for the Ultimate Power Scheme in my Lenovo Thinkpad P16 (Gen 2). I believe it was not listed as an available option.
I think I was able to insert a short bit of Code using Powershell to opt for the Ultimate Power Plan.
But it reverted back when I restarted the laptop.
The bit of code Frank1119 supplied fixed the issue in one of my Lenovo Thinkpad P16 laptops.
I later had a similar problem in a near duplicate laptop (even with the Ultimate Power Plan selected). Frank1119 was able to help me fix that issue with Throttlestop.
Correct, and I understand. But I have already set up three new partitions to replace those that were blitzed. But my question remains - Why are D and E drive letters not available to be used on the new partitions? Why doesnāt Windows know that these partitions are new and therefore eligible to be used on the new partitions? As it stands, D and E are just not in the list any more. Because the data partition holds all my rs and vsts, and was originally E (now it is G), I am having to go through all my songs and change the paths from E to G. I can do it, but there 500 + songs and it takes time.
Also please:
1 Where do I find the script to reinstate the Ultimate plan?
2 What app do I use to apply it?
It has been years since I used windows but I vaguely remember that you could right click on a partition and change the drive letter.
Does that not work anymore?
No, the two drivers letters I had before (D and E) are np longer in the alphabetical list. They are physically not there.
Please, could you post a screenshot of diskmanager. It lists all disks, volumes and partitions. Make the window large enough to show all entries (especially the lower half of the window).
I uploaded a script to do that along with some guidance in the topic @jeffn1 is referring to. The āappā isnāt an app. Just a powershell window. You can start that by using cmd and then powershellor directly starting powershell. Make sure to start it as administrator. From that window you can run the script (whatever.ps1).
The script creates the āultimateā powerplan and then activates it. If you run it multiple times, it makes sure that Windows is not piling up dozens of powerplans (because deactivated powerplans do not show up in the control panel).
Done. As you can see, D and E are missing.
I heard something about Windows Network Shares. Not sure what that means.
Iāve been in touch with Jeremy at Bitsum because I use their Park Control app. He showed me a way to invoke the āBitsum Highest Performaceā mode. It worked and I now have that option in Windows 11. I have asked and I presume that it is the equivalent of the missing Ultimate one. But you have to buy their Park Control app which isnāt very dear.
