Hi,

In the case of an update, the first few startups may be slow, but after booting up the computer should work correctly. The slowness could be caused by software or drivers.

You can try optimizing by opening the command prompt (admin) and running the commands: sfc /scannow and dism /online /cleanup-image /restorehealth. Wait for the process to finish and restart the computer.

Then perform a clean boot and uninstall applications that you do not use.

In the search bar, type "temp" and select "all," then delete everything.

After that, restart the PC and see if the startup is faster.

In the search bar, type "%temp%" and select "all," then delete everything.

I can instruct you better on the optimization.

If it is a laptop or desktop, if possible, could you provide the laptop model or your desktop configuration?

After a Windows 11 update, performance issues and app problems are common. Use these steps to improve speed and help apps like Filmora work better:

1. Install all pending Windows and driver updates
   • Select Start > Settings > Windows Update > Check for updates.
   • Install everything offered and restart.
   • Then go to Windows Update > Advanced options > Optional updates and install any available driver/optional updates, then restart again.
2. Scan for malware
   • Select Start > Settings > Privacy & security > Windows Security > Virus & threat protection.
   • Select Quick scan and let it finish. Restart if requested.
3. Free up disk space
   • Go to Start > Settings > System > Storage.
   • Use Storage Sense (turn it on and choose Run Storage Sense now or Clean now) to remove temporary files.
   • Still in Storage, select Temporary files, select items to remove, then Remove files.
   • Optionally run Disk Cleanup: open Start, type Disk Cleanup, select a drive, and clean unnecessary files.
4. Remove unused apps and reduce background load
   • Uninstall apps not needed:
     • Start > Settings > Apps > Installed apps (or Apps & features), select the app, choose Uninstall.
   • Disable startup apps:
     • Press Ctrl + Shift + Esc to open Task Manager.
     • Go to Startup apps, right‑click unneeded items, choose Disable.
   • Turn off background activity for heavy apps:
     • Start > Settings > Apps > Installed apps.
     • For a selected app, choose Advanced options and set Let this app run in the background to Never.
5. Adjust performance and power for speed
   • Visual effects:
     • Select Start, type Adjust the appearance and performance of Windows, open it.
     • On Visual Effects, choose Adjust for best performance.
   • Power mode (laptops/desktops where power use is not a concern):
     • Start > Settings > System > Power & battery (or Power & sleep).
     • Set Power mode to Best performance, or in Additional power settings choose High performance.
6. Optimize drives
   • Select Start, type Defragment and Optimize Drives, open it.
   • Select the system drive and choose Optimize.
7. Check which processes are slowing the PC
   • Press Ctrl + Shift + Esc to open Task Manager.
   • On Processes, sort by CPU, Memory, and Disk to see heavy apps.
   • Right‑click apps not needed and choose End task (avoid ending system processes).
8. Restart and test Filmora
   • After doing the steps above, restart the PC.
   • Try Filmora again. If it still does not work, reinstall Filmora with the latest version that supports Windows 11.

If the PC is still very slow after all of this, hardware may be too old for Windows 11 and performance gains will be limited.
