    Quick advice req'd on reinstalling Win 10 1809 on lagging laptop


    Hi everyone. I have an old Acer laptop with win 10 Home build 1809. I'm guessing it's around 6 years old but it is 3.0 MHz i5 with 8 or 16 Gig. Not surprisingly it's gets slower with time but now it's almost beyond usable. A scannow found corrupted files it was unable to fix and all my old restore points are also corrupted. A reboot takes about 15 minutes and even waking from sleep takes 10 minutes before right-clicking on the desktop doesn't result in a busy mouse cursor. Iv'e tried figuring out if theres a program or virus at fault but it's all very frustrating. I just want to reinstall clean.
    Somewhere around here I have a recovery USB I made when I got the laptop but I'm afraid it may be full of the bloatware that the laptop came with. There is also no Windows sticker on the underside but I am assuming the number I pulled using an app is the correct licencing number?
    I've got the drive partitioned into 3 parts as well. What are my options for a clean install without losing data and ideally drivers and apps? I only use this thing for watching TV anyway as I have a a skookum laptop for other stuff.
    Thanks

    None. A clean install means you start CLEAN. No apps or data. If you have data stored on a partition separate from the C: drive partition, then you can do the clean install on the rest of the drive leaving your data partition intact.

    You can try this:

    I would be looking at testing the hard drive to ensure it is not failing.

    Your 3.0MHz is actually 3.0GHz.

    SFC may work but you want to read this first and run the commands listed:

    There's other information about it on this forum.

    Consider installing a cheap SSD for much improved responsiveness if your laptop allows the disk to be changed.
