I changed the key to from "2" to "4" to disable it to time difference between start up speed booting to desktop as well as CPU load on start up.
when I try changing back I ended up using 0 instead of hex value of 2 now it just stuck on window boot/blackscreen. is there a way to recover from this? I can access the partition from another boot (dual boot windows).
Hi, when I had a problem like this, having used reg keys from the tutorial to set some services to default, I booted to Advanced Startup options and ran System Restore.
Problem was solved.

You could try researching offline registry editing.
Code:Edit Registry (if you can not boot into Windows) Boot Windows USB - Repair - Troubleshoot - CMD - type/enter c: cd windows cmd regedit Select HKLM (or required key) File - Load Hive - %WinDir%\System32\Config (select required Hive, like System/HKLM) SAVE - Unload Hive (when you finish editing)
yea couldn't boot into window. I boot from USB and use the repair option from install screen. CMD defaults to x:\sources (assuming thats the USB path for installation)
I get up to the part where navigating to the broken partition's regedit, but what do you mean by File load hive/save unload hive? cause when I type regedit it just open up the registry window normally, do I not just change the value and it should auto save? or does it not save on its own normally like under OS environment and needs manual saving due to repair environment?
also if its just saving, whats the need for load hive? sorry for so many questions
Hi, I did suggest you research offline registry editing e.g.

I'd regard this as technically advanced- far better to take due precautions... in future. Good luck!
I have found 2 of the 3 links you provided, the latter 2 are just general steps and I can't really understand it unless I have an example. the first link is great but im still a bit confused.
let me break it down to make sure I have the right understanding here.
1. boot up to the partition using repair, once CMD comes out type regedit
2. locate the boot partition with corrupted registry
3. load hive SYSTEM file from %windir%\system32\config\SYSTEM
4. just randomly name a key?
in the 1st link example, he adds a key named "my key" but the registry path is totally different from the one what he is trying to fix is what I don't get, what is the purpose for this. cause it seems to me he ended up just simply go into the path he wanted to edit, edit them and unload. so whats the need for mykey he created when loaded hive?
also in my case, when I went into HKLM -> system -> currentcontrolset -> services -> sppsvc, the sppsvc folder/key is missing, how do I edit the start value if the entire key is missing.
Hmmmm
interesting that used to be the W7 system activation, you gone non-genuine???
check your registry entries here, from this thread

the sppsvc key suppose to be there. theres a dword key or qword key whichever it is, had a start value of 2 and I changed that to 4, then when I change it back I thought it was originally at 0 rather than 2 which caused this issue in the first place. but when using the recovery method the entire sppsvc is not there.
Boot the dual boot computer from the good partition, start regedit, highlight "HKEY_LOCAL_MACHINE", click "File", "Load hive", click "This PC" in the left window, double-click the problem drive in the right window, then type or paste "Windows\system32\config\system" into the "File name" box, click "Open", enter "temp" as a key name and click "OK". Then expand and highlight "HKEY_LOCAL_MACHINE\temp\ControlSet001\Services\sppsvc" in the left window and inspect the "Start" entry in the right window. If it is "0", change it back to "2", scroll back up in the left window, highlight "HKEY_LOCAL_MACHINE\temp", click "File", "Unload hive", confirm the unload, then try to start the disabled system.

yea that seem to be the issue. it seems I didn't need to load hive from USB boot because the other partition works as well. only thing is I need to load the SYSTEM file from the corrupted window partition and then edit them.
also once loaded, it is ControlSet001 not CurrentControlSet, not sure why but I guess current means current while not in use its just 001 which is primary? editing 001 fixed it for me
