Hey,
I did as said but don't know why, my favourites are now stuck. How can I bring them back as it was at the beginning?
This is how it looks now, when I click on it nothing is happening

:
Hard to believe it didn't work :sarc:
I also did the change and am finally happy !
Here, open a Command Window, run this command and post the screenshot:
(everything in one line )
reg query HKEY_CLASSES_ROOT\CLSID\{323CA680-C24D-4099-B94D-446DD2D7249E}\ShellFolder
This will display the contents of the key. BTW, here is the output so you can check by yourself:
HKEY_CLASSES_ROOT\CLSID\{323CA680-C24D-4099-B94D-446DD2D7249E}\ShellFolder
Attributes REG_DWORD 0xa9400100
PinToNameSpaceTree REG_SZ No
Perhaps you mis-read the original post from DeathAngel and made a mistake by typing a0940100 instead of 09400100. Note how subtle it is but if you break in two words it becomes evident (remember, the value is a double 32-bit word):
a094 0100 <-- original
a940 0100 <-- modified
Yeah, you can use the command "reg" to check, delete etc registry keys... type "reg /?" to see the options. Just in case you dislike the graphical interface...
To modify that value, use it like this (first it deletes and then re-adds with the new value), so here's the full hack after all:
reg delete HKEY_CLASSES_ROOT\CLSID\{323CA680-C24D-4099-B94D-446DD2D7249E}\ShellFolder /v Attributes /f
reg add HKEY_CLASSES_ROOT\CLSID\{323CA680-C24D-4099-B94D-446DD2D7249E}\ShellFolder /v Attributes /t REG_DWORD /d 0xa9400100 /f
Reboot. Done.
[[ :tip: to revert to original, replace 0xa9400100 by 0xa0900100 and re-run]]
