Met all kinds of issues while using Windows 10. Resolved them usually by googling online. List some of typical ones here:
- Fix High CPU Usage by Windows Software Protect Service (Sppsvc.exe)
- Microsoft Office can’t find your license for this application or Windows is not activated
- Windows 10 Defaultuser0 password Issue
- Can’t open gpedit.msc
- Account restrictions are preventing this user from signing in
Fix High CPU Usage
This case is caused by Windows Software Protect Service (Sppsvc.exe)
Microsoft Office can’t find your license for this application or Windows is not activated
Issue is relating to disabled Windows Software Protect Service (Sppsvc.exe).
If value is 4 and sppsvc.exe Software Protection service is disabled. You will need to change value to 2 or 3 to enable it to get your Microsoft software license activated automatically.
Windows 10 Defaultuser0 password Issue
Step One:Boot up your computer.
Step Two:When booted up hold down your “shift” key and click on the restart button on the bottom right of your screen.
Step Three:This will bring you into the Advanced Option menu. From there click on “Troubleshooting” and then “System image restore”.
*What this will do is bring you to your system restore screen and prompt you with restore points*
Step Four:Select your most recent restore point and start the restore process.
*When prompt to select an account you will see administrator. Simply click is and DO NOT PUT IN A PASSWORD leave it blank*
*Will only be one restore point if a clean install of windows 10*
Step Five:When your computer finishes this (time will vary) simply restart when prompt and it will start loading up the Windows 10 Setup screen.
Create your Account.
What the restore did was bring your computer back to the point where windows 10 just finished installing but hasn’t setup a profile yet. This will just bring you through the step by step instructions to create a user account you can actually use.
If you did not save a restore point, you had better to reset it to wipe every personal stuff. Click “Troubleshoot”, then “Reset This PC”, and finally “Remove Everything”. You’ll drop to a black screen with the word “Preparing” in the large, friendly letters characteristic of Windows 10. Eventually, you will return to a blue screen asking if you want to clean the drives as well. Click “Just remove my files” and then the “Reset” button on the next page. The screen will go black again and display the Windows 10 progress indicator while it chugs through the reset process.
Can’t open gpedit.msc
Tried to use gpedit.msc and got following messages:
Failed to open the Group Policy Object on this computer. You might not have the appropriate rights — unspecified error.
Rename machine folder name to something else at C:\Windows\System32\GroupPolicy,
You also can choose to delete all the files inside the Machine folder instead of renaming it. Windows will automatically recreate the required files when you relaunch the policy editor.
Account restrictions are preventing this user from signing in
Account restrictions are preventing this user from signing in. For example: blank passwords aren’t allowed, sign in times are limited, or a policy restriction has been enforced.
I am sure there is no blank password and limited sign in time. It must be restricted by group policy.
