mengatasi windows 7 masuk user profile temporary / selalu baru lagi

This remedy is taken from this Microsoft KB article, but ill mention it here for completeness and add my thoughts to each task.

http://support.microsoft.com/kb/947215

Go to Start and run REGEDIT

Go to:

• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

In this key, you should see something similar to this:

The S-1-5-21 keys actually are the configuration of the profiles in windows. one thing to notice is that there are two that are strikingly similar (S-1-5-21-1079119....) but with one difference, the .bak at the end of the key at the bottom.

Lets take a look inside the key:

A healthy profile should look like this:

A cool thing to note is that the ProfileImagePath points to the home directory of the user. An unhealthy profile will display the ProfileImagePath to c:\users\temp, and the RefCount will have a value higher than 0.

 

To solve the problem, login to an administrator account other than the one that has the issue.

Next modify the key name that doesn't have the .bak to .ba.

Now Rename the key that HAS the .bak and remove the .bak.

Finally modify the key name that HAS the .ba to .bak

Once that is done, you will need to modify a few more things in the key without the .bak.

We need to change the RefCount to 0

We need to clear the state in State to 0

 

Now its time to reboot and try to login.

This worked for me. What your more or less doing is manually changing the state of the profile from the backup state to a local state

Cara reset group policy windows 10

 

Here's how I eventually got the hard-core non-updating windows 10 machines back to normal.

• Restart
• Log in as a local administrator
• Stop Windows Update and Background Intelligent Transfer services
• Clear out c:\windows\softwaredistribution\
• Clear out c:\windows\system32\grouppolicy
• gpupdate /force
• Restart

In SOME cases, the Windows 10 Update Assistant would at least bump up the current patch level, in some cases not.

Cara biar firefox prosesnya tidak banyak

 In Firefox 68+ you can only disable multi-process by creating an environment variable named MOZ_FORCE_DISABLE_E10S and set its value to 1. You can either use a .cmd file to start Firefox or set this variable in the Windows Control Panel -> System.

Trik ini hanya berlaku hingga versi 80.0.1 . Versi selanjutnya sudah tidak mendukung. 

Untuk mencegah update, file maintenance dan update exe perlu dihapus.
