Hey, the question arised in another thread, so here is step by step tutorial how to use windows as a STABLE and RELIABLE work environment
(that is NOT filled with useless crap and Ads/Bloatware by windows)
In other words.. how to get Win7 ease of use and stability in Win10
The part with Linux is aimed at when you can not boot into windows anymore but need your data from there.
still do a full data backup (+to an external drive) before you start doing anything! LINUX PART
get 3 items:
1 USB stick 4gb or more
2 external hdd for data backup (not needed if you have 2 partitions or drives inside the laptop)
3 other PC
-start 3 and download manjaro linux or ubuntu (or other, i think its easiest to use)
-if 3 is windows, get rufus usb tool, burn the downloaded Linux iso to 1
-insert 1 to defective laptop
-turn laptop on, boot from 1, lenovo usually has a small "reset" hole somewhere on the site, you get to bios oor boot menu with this
-boot into linux, let it sit 2 minutes to calm down so you work faster
FOR USB BACKUP HDD
-insert 2 to laptop, KEEP 1 PLUGGED IN!
-copy all important data to 2 with the file manager from linux
FOR INTERNAL 2nd HDD/PARTITION
-copy all important data from windows boot partition to other partition
-EXTERNAL USB BACKUP RECOMMENDED! in case virus/RAT is on 2nd partition it can infect new windows in no time again
Now, the fun part.. reinstalling windows (yay, days gone lol)
-shut down laptop
-insert 1 back to 3
-download "windows 10 enterprise N LTSB 2016 iso" from a reputable source (see below) (NOT 2019 ltsC !!)
-burn iso to 1 with rufus
-remove any internet connection from the laptop before any installation!
-insert 1 into laptop
-boot to usb
-start windows install
-delete all partitions (except data backup ofc)...
-YES, delete recovery, boot, ... all except data backup!
-install windows on BIGGEST now empty space, in case there is more than one
-if you wish, clean out windows with "w10 better privacy script"while installing and "W10privacy" after installation
In fresh installed windows:
-right click start button
-go "programs and features"
-click turn on/off features on the left
-turn off what you dont need like internet explorer, media features (WMP), XPS services ets (i disabled all except the .NET packages)
-connect internet
-activate windows (see below)
-update
-restart
-update
-restart
-aaaand again (will take some time .. yep... windows :D)
if updated, BACKUP!!!!! to external drive (NOT windows system restore, its useless)
save it as "fresh" for example, this version will stay untouched as long as you have this PC and use Win10!
now start installing your programs
keep it clean.. reevaluate what you really need installed and what is enough as portable version
backup again ("rolling backup"), this version is your rolling backup, keep 2-3 revisions of this.
when something goes wrong but you do not want to start from scratch, this is your restore point
let this backup run once a day
if you are very scared of data loss, choose a better backup solution like NAS, Gdrive for documents (more than 1 place), work with the cloud if privacy allows it
and get a good backup program with incremental daily/hourly backups, they dont eat up as much space as full backups
watch out that it has a bootable usb/iso tool where you can recover your backup in case your windows is dead
Now you have a STABLE Windows release without useless bloatware like windows store and "candy crush saga" advertisement.. you will get security updates for the next few years without getting all the bloat the new versions are getting.
I have tried multiple versions from home to pro to the new enterprise LTSC 2019, but i could never achieve the smoothness and "it just works" with them like i do easily with LTSB.
-----------
I hope this helped some of you, if yes.. drop a thanks or a comment 
However, as always, i recommend running a good stable Linux Distro like Manjaro as main and run Win10 only in virtualbox.. much less headache and only (measured by various youtubers) 1% performance loss when gaming (and we only do office work here)
