Vielen Dank! I deleted the whole \WPA section, and it rebooted fine. Windows did recreate \WPA\Key-bla and \WPA\SigningHash-blah, though. It's the US English version.

Hello, Although I wasn't affected by the spread of the WannaCry ransomware, I checked if there was a way to extend support for XP, and added the PosReady key. After reading more about this hack, I'm having second thoughts, and would rather remove it. Problem is, even though my user account is Computer Administrator by default, no matter what I try, XP won't let me delete those keys: [HKEY_LOCAL_MACHINE\SYSTEM\WPA\PosReady] [HKEY_LOCAL_MACHINE\SYSTEM\WPA\WEPOS] [HKEY_LOCAL_MACHINE\SYSTEM\WPA\WES] I did follow the instructions to take ownership of this key and sub-keys, all to no avail. When booting with "ERD Commander 2005 for XP", it says "System Root = (None), Operating System = None - Do not attach to a Windows installation." Finally, the PCRegedit.iso mentionned in the sticky post of this thread can no longer be found here (but remains accessible here). What could I try to get rid of those keys? Thank you.

Thanks for the info. I did try changing the BIOS from AHCI to IDE before asking for help, but it didn't work. But this time, it did. It might have to do with the fact that I booted a Linux USB keydrive to reduce the size of the first partition to something smaller, but I'm not positive. Although XP won't boot if I set the BIOS back to AHCI, I can live with that. Thanks for the help. WSFU is a very useful tool. Edit : Not a good idea, as this is a test host and images I did previously in AHCI mode with Clonezilla won't start (at least Windows7 won' t start. Looks like I'll have to learn how to add the SATA driver in the XP ISO.

Hello I'm having a problem installing XP on an Acer Aspire 3810T laptop. Booting the laptop from a USB keydrive with WinSetupFromUSB works fine, but no matter what I try, it won't see the SATA drive. I tried WSFU's "Autodetect and use F6", or copying Acer's AHCI driver onto a second USB keydrive and hitting the F6 key in XP's installer, to no avail: Hit "S": Also tried changing the SATA drive in the BIOS from AHCI to IDE, nogo. Could I somehow copy the AHCI driver onto the WSFU keydrive? Thank you.
