Effective Fixes For The Problems

To provide the resolution to your question – why is my Windows 10 so slow, here are some fixes that you can apply to your windows 10.

Why is my windows 10 so slow fixes

  • Corrupted Windows system files

    The system may undergo several problems like driver errors, blue-black screens, and so on.
    Fix it:
    Windows 10 gives two major tools to solve this issue. They are DISM (Deployment Image Service And Management) and SFC(System File Checker).
    DISM :
    Step 1: Go to Windows Search bar and type PowerShell and select run as administrator.
    Step 2: Type dism.exe/Online/Cleanup-image/Restorehealth and hit enter. This will begin the DISM search for corrupt files and replace them.
    SFC :
    Step 1: Go to Windows search bar and type PowerShell and select run as administrator.
    Step 2: Type “sfc/scannow” and hit enter. This process will find and replace corrupted files. Restart your system once it is done.

  • Running too many programs at once

    If so many programs are running at once then it may slow down your PC and the applications take more time to load and may freeze the screen so frequently.
    Fix it:
    Go to the Task Manager and find the application that is using more memory.
    Step 1:  In the search bar, type “Task Manager”.
    Step 2: Open Task the manager and find the applications that use more memory. You can sort the application based on the usage of the memory. Right-click on the Task and end it. End all the background running applications. This may free up the RAM and CPU so that your PC will run faster.

  • Anti-Virus software is extremely active

    This software slows down the PC performance and takes more time to respond. The antivirus running in the background may consume more processor power which reduces the performance of the system.

    If the hard drive is full, about 95% then the performance of the processor will be reduced to 50%. The lack of storage for temporary files makes OS function improperly.
    Fix it:
    Check which file is taking more storage in C drive and delete those unnecessary files.
    Step 1: Open storage in Windows Explorer.
