windows 10 getting slow

my system, in a recent few days, suddenly getting slow

I don't know why it happens.

Is it the only way to get it fixed is to clean re-install the windows 10?

any other way to avoid re-installation?

I've tried to update and restart a couple of times but it doesn't seem like improving a lot.

I did not install anything particularly big or eating up the memory recently.


btw, I haven't done clean reinstall for a couple of years. I've forgot almost everything.

Anything I should be aware of during reinstallation and in fact, how to re-install a windows 10?

I never used ghost or image or anything like that is it true that I can avoid full re-install everything by using ghost

 

HDD or SSD?

Task Manager shows anything out of the ordinary?

Might be just a longer/bigger AV scan that its taking some time, and rebooting only makes it take longer.

 

Didn't you know, random slowdowns are a feature of Win 10…

Anyways, you can do a reinstall and still keep all your installed programs. Just make an image of the same version of win 10 you're running home/pro, 1803/170, etc. there are instructions on how to do so on Phoenix's clean install thread IIRC). After you have the image you can just mount it (double click the iso, or open the USB) and run setup. from there it'll give you the option to install with keeping the user files and "apps" (my instructions probably aren't the clearest so if anybody else wants to chime in…)
Alternatively, you can check out Phoenix's thread and do a clean install, starting from scratch (possibly the best idea if it's been a long time since your last install)

I can't say for sure if that'll help your situation, but I did try this a while back and it did sort my system out - for a while, until MS released the next "update". Like I said my attempt at doing this was a few versions ago so I don't know if its still effective with the more recent versions

 

A most unhelpful in itself here. Unless you have something to backup - making baseless comments does no one any help.

How one keeps their system up to date isn't that fault of MS if your update fails. Best and better way how I mine was accomplished was each time reboot to the previous saved image made by Acronis and then do the update and software/driver update as needed and then make a image of the latest update. This way one insure there was no problem with the latest image backup. Just update and update without fixing problem will cause more problems down the line.

 

Random slowdowns a feature… That was a joke son (mostly)

MS updates don't necessarily have to fail to mess a machine up - just look at the track record of 1803 or the other "Creator Updates"

Regardless, I'm just relaying my experience. Doing a install overtop of my existing one (this supposedly creates an "as new" installation) really did improve performance by a noticeable degree. It also saved me from having to reinstall everything all over again. Could be an option if someone - like myself - hasn't been making regular backup images

 

@kenny1999 Disable system restore completely and for me the w10 slowdown is NIL on my old PC with HDD.
You need to delete all restore points then allocate 1% space and finally Disable System protection to disable system restore.

 

Jokes works where it is needed not when asked for help.

Look at User track record and how they update is what leads to more problematic update as well.

Experiences vary and if done right it can eliminate problem and then one can verify a O/S update problem or User created update problem.
