Could you send me a debug log for this?

• On the DisplayFusion Settings > Troubleshooting tab, change the Logging drop-down to "L1: Log Minimal"
• Reproduce the issue and note the time so we'll know where to check in the log file
• Click the "Export Info to File" button on the Settings > Troubleshooting tab
• Reply with the file attached
• Disable debug logging after sending the log

I've repeatedly killed/restarted explorer.exe and also restarted DF, neither of which make a difference. The only thing that makes a difference is the titlebar buttons. ]]> https://www.displayfusion.com/Discussions/View/df-1111-killing-performance-of-winfile-explorer-on-win-10-22h2/?ID=0195ac6d-12a5-77f9-9100-af2ec8a190dd#2 Wed, 19 Mar 2025 20:25:07 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/df-1111-killing-performance-of-winfile-explorer-on-win-10-22h2/?ID=0195ac6d-12a5-77f9-9100-af2ec8a190dd#2 DisplayFusion Thanks for the kind words, that's great to hear!

Does this issue happen immediately after launching DisplayFusion, or only after it's been running for a while? If it does happen immediately, does it also happen immediately after a fresh reboot of the machine? ]]> https://www.displayfusion.com/Discussions/View/df-1111-killing-performance-of-winfile-explorer-on-win-10-22h2/?ID=0195ac6d-12a5-77f9-9100-af2ec8a190dd Wed, 19 Mar 2025 03:23:04 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/df-1111-killing-performance-of-winfile-explorer-on-win-10-22h2/?ID=0195ac6d-12a5-77f9-9100-af2ec8a190dd DisplayFusion Hi,

My issue seems to be a recurrent problem. I've already set the DF Compatibility Settings for explorer.exe to disable application hooks. It seems that the titlebar buttons are killing things, and I *USE* the titlebar buttons all the time. With them active, Windows File Explorer crawls.

Has there been any progress for this issue?

Despite my occasional complaints, I truly love the product and appreciate all who work on DisplayFusion! ]]>
