Windows 11 has become slow after startup
My Windows 11 PC was running normally when I first installed it, but lately the startup process has become noticeably slower. After logging in, I sometimes have to wait before the taskbar and File Explorer respond properly.
I've already disabled some unnecessary startup programs, but it hasn't made much difference. What should I check next? Are there any simple ways to improve Windows 11 startup performance without changing important system settings?

Because the delay occurs after sign-in, while the taskbar and File Explorer are unresponsive, the bottleneck is probably a startup app, service, storage activity, or profile initialization rather than firmware boot. Open Task Manager > Startup apps, sort by Startup impact, and disable only nonessential entries. Restart and compare the time from sign-in to a usable desktop. During the delay, check Task Manager’s Processes and Performance tabs for disk, CPU, or memory use and note the responsible process. Ensure the system drive has free space, then install Windows updates and manufacturer chipset and storage drivers. If no process is obvious, perform a clean boot and re-enable services in groups to isolate the offender. Run DISM /Online /Cleanup-Image /RestoreHealth and then sfc /scannow from an elevated terminal. Finally, test a new local account. Avoid registry cleaners or broad service-disabling scripts because they can hide the cause or remove required components.
