Windows 10: I can not access regedit,; is there a way to sideload it onto a USB and run it from that?

I recently accessed my system registry via regedit attempting to change my main downloading drive. I changed the C:\ drives to D:\ drives and restarted my PC. When I rebooted the PC I was no longer able to access many functions and most programs from the C:\ drive. I thought to change it back but now I can not access regedit nor can I access the system restore options. The error says it can not access those drives. Clearly they can because I can still access other system interfaces. How do I go about getting back into regedit? Is there a way to sideload it onto a USB and run it from that?

Sideloading on Windows phone 10

Hi,

Thank you for being part of Microsoft Community.

In Windows 10, sideloading is different than in earlier versions of Windows:

• 
  You can unlock a device for sideloading using an enterprise policy, or through
  Settings
  
• 
  License keys are not required
  
• 
  Devices do not have to be joined to a domain

Windows Syskey: Any way around it?

Found this..... maybe?

1. Boot from windows install cd.

2. When the Install Windows page appears, click Repair your computer to access system recovery options.

3. Run System Restore to last point before syskey password blocked access. (This will fail, but must be done). Click run system restore again (this will take you back to the options list)

4. Open Command Prompt from the options list.

5. Open Regedit (Type regedit into the command prompt). Regedit will open.

6. Navigate to: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Lsa, and change 'SecureBoot' value to 0.

7. HKEY_LOCAL_MACHINE \SAM\SAM\Domains\Account Change F value to 0000

8. Reboot and Login

 

How can I backup and sideload Windows universal apps?

Hello!

I know almost all Windows Universal apps and games are available at Windows Store, but it is not convenient to download many games one-by-one for each computer. Probably there is a way to extract the apps to APPX or EAPPX files (what is the difference?) and then sideload them from a USB Flash drive using PowerShell, but this is not very convenient. Is there any utility to do that the easy way with a mouse? I am mostly interested in the sideload part. I have seen some sites having available some Windows games in EAPPX or XAP format and I want to sideload them without having to download one-by-one from Windows Store. If I understand correctly XAP format is for Windows Phone apps. Can that be converted to APPX or EAPPX? Can I sideload it directly without conversion? Could you suggest any site to download windows games (free and legit of course)?

Thank you in advance

PS: I have downloaded APP Installer from Windows Store, but I don't see it available in my apps and when I double-click on an EAPPX file still ask me what application to open it with. The "search in store" option doesn't find any suitable application. Am I doing something wrong?
