You might have broken links on the Desktop.

[mohamedibrahim54]

how can I fix links?

[lkishalmi]

If you have broken links, you can remove them. I'm not a Windows user.

Here a few JDK bugs which are related to delays before the file chooser shows up:
JDK-8265446 "JFileChooser slow with network shortcut on desktop"
JDK-8268731 "Slow opening of the JFileChooser when desktop contains broken lnk file"
JDK-8213583 "Error while opening the JFileChooser when desktop contains shortcuts pointing tto deleted files"

and when the file chooser doesn't show up at all:
JDK-8305072 "Win32ShellFolder2.compareTo and equals are inconsistent with each other" also see #6361 for workaround

The comments on the first three issues seem to indicate that this should already work on up2date JDKs if the security manager is not use? Maybe I am reading this wrong. The fourth issue is a different problem, connected to the windows specific quick selection panel on the left side of the file chooser.

JDK-8265446 does have a reproducer so it should be easy to check if it happens to someone.

If it is indeed SM related, would be curious if #3386 (or #7928) would fix it as side effect.

Was sent to this post from here #4673 (comment)
I don't have any of the above items that should cause the slowness.
I installed Netbeans 20 and executed as follows, but opening projects is still slow.
C:\devenv\apache\netbeans\netbeans-20\bin\netbeans64.exe --jdkhome C:\devenv\apache\jdk\jdk-21.0.2 --userdir C:\devenv\apache\netbeans\nbuser\20 --cachedir C:\devenv\apache\netbeans\nbcache\20

about the previous comment "The last time I heard something like this was probably in the late 90s." Thank You :)
That's right, I've been in the industry since 1981 and I've used netbeans from the beginning and over the years have seen become slower and slower and imho over-engineered.
Netbeans rocks!, I Love the IDE.

@coffeebeantraining you could still try the reproducer in JDK-8265446 I think. It would be good to clarify if the security manager is the only issue in play here.

Yes, it couldn't possibly be Windows that's got slower and slower and over-engineered! 😄 NetBeans has certainly not got slower here. Whatever this issue is, we know it's OS specific.
