Windows 10: Could not log in after I changed registry permission and restarted device

So I was trying to install NordVPN, at the end of the installation it gave me an error, something about RegSetValueEx and error 5, I did some searching and it requires me to edit registry permission.So i went ahead and did that, I might have done something wrong because after restarting my device, I could not even attempt to login, or the input prompt to login would not even show. It would just sit on second picture attached for like 20~30 seconds, then change back to the first picture as if nothing happened. Thanks!

Any way to edit the registry without loading Windows?

You will need to find a way to grant yourself permissions for full control of that hive/key.
Just as the "Trusted Installer" has.
You may have to log on as admin to do this.

Grant Read Write (Full Control) Permissions on Registry Keys (Fix Cannot Import and Access Denied Error in RegEdit)
How to change Registry Permissions with RegIni.exe (VBScript)

And, a search to start you on your quest.

I did it a long time ago, to get rid of & edit some hives, keys, etc.
Goodluck.*Smile

 

xp ntfs permissions erased - help!

NEVER, ever, remove FULL CONTROL permissions in the Access Control Lists/rights priveleges from:

• Administators Group

• YOUR local Administrator User

• SYSTEM

on NTFS rights on your disks (via Explorer.exe rightclick properties menu, security tab) that use that filesystem, OR in the REGISTRY either, via rightclick on HIVES/KEYS permissions popup menu options...

(Sure way to lock yourself out, period, & I have done it myself early on w/ NTFS filesystems &/or the Registry before... only way to learn sometimes, is making mistakes!)

* Keep this in mind, those of you that start experimenting w/ security @ these 2 levels!

APK

P.S.=> Leaving them @ FULL POWER, in both areas, usually 9/10 times allows you to get back into your rig (logging on as your LOCAL ADMINISTRATOR USER, to fix it), & make alterations to rights/acl's as needed, to "get it right", eventually... especially when you're still learning/experimenting! apk
