Restart (not shut down) your PC to flush out your RAM.
Open Task Manager.
Select the Processes tab, then leave that window open to monitor your system.
When your PC is lagging, please provide a screenshot of that Processes tab.
2
Right click your Start Button and open Device Manager.
Please provide a screenshot of that full Device Manager window.

2026-04-05T06:52:48.8166667+00:00 Thank you for the screenshots, there is no problem indicated with the drivers, they are all installed correctly, also, none of your hardware components are under any pressure that would cause your system to be slow or lagging.
The best option is to perform an in-place repair with the Windows 11 ISO.
Please ensure you download the ISO in the same language as you use for the Windows UI, follow the steps, this is then not like re-installing Windows, it is just like an update and your personal files, settings and installed software will not be affected.
Click this link:
https://www.microsoft.com/software-download/windows11
to download the Windows 11 ISO
When the ISO file completes downloading
Disconnect from the Internet
Disconnect all external devices with the exception of a mouse or keyboard.
Temporarily disable any 3rd party Anti-virus you may have installed
Then, in Windows File Explorer, double click the ISO and then run Setup.exe and select the Install option.
Very Important - ensure you select the option to keep your files and apps.

- On Processes, look for apps using a lot of CPU, Memory, or Disk.
- Right‑click and End task for apps not needed.
- On Startup apps (or Startup tab), disable apps that do not need to start with Windows.
- Optimize drives
- Select Start, type Defragment and Optimize Drives, open it.
- Select the system drive (usually C:) and choose Optimize.
- Adjust for best performance

- On Visual Effects, select Adjust for best performance, then OK.
- Set power mode to Best performance (if on mains power)
- Start > Settings > System > Power & battery.

- Note: This uses more power and can make laptops run warmer.
- Close unused apps and restart regularly

- Restart via Start > Power > Restart, then only open the apps needed.
If the PC is quite old, these steps may help only a little; in that case, hardware upgrades or a newer device may be required for big improvements.
