I am running a couple PC's, one has WIN10, continually updated. The end of support is ending soon, and the push is to get the WIN11 upgrade. I have some very important programs running. on ver10.
Has anyone experienced any significant issues when doing the upgrade that need to be looked out for?
Any incompatibility, etc.?

 

easy answer is yes,
majority of change to w11 ( i refute the lable upgrade )
Seem to go well,
till it dosnt ,
its amazing how things like active x and java seem to be intertwined in engineering programmes.

as ever , take a snaphot backup is advised .

the question is, if one does have problems, w10 is gone..
so one has to think about alternatives ..
I know of companies that are purchasing new pcs,and moving programs and data over from w10 machine rather than try to change in place .

good luck, dont leave it till last minute ..

Can't you setup a test Win 11 machine or VM? such a test is the best way, relying on anecdotal views is a bit risky.

What are the important apps you're concerned about?

 

Win 10 will work next year. There is not a drop-dead date.

My tax software will only work on Win 11. So I do have a need to change.

I updated a computer that we don't use much just to see how it goes. I also updated the hard drive at the same time. The old drive has Win10 and the new SSD has Win 11 that was upgraded from Win10. Now just with a BIOS change I can swap C: and D: if I want to go back. The new SSD cost $45, 1T byte M.2 drive. That made a huge difference.

It works. Was not hard. I have not tried much.

 

Some of my programs also would not work on 11... Fortunately they are not used often so i created VM for those.

 

Alway back up everything. This can be slow but necessary. Don't forget browser stored passwords.
Lots of time consuming mistakes. The idea is to copy everything to another hard drive. Better yet install a new hard drive.
It is then that you format and set partitions to a new hard drive for preparation for Windows 11.
on a separate flash drive you have downloaded the latest Windows 25H for your processor.

Hold down the right key on your computer to enter bios and boot new OS from flash drive.
I recommend doing this with linux first. I used Kubuntu KDE now has the utilities mounted on 2nd partition.
I might not use dual boot much but I had to move things around several times on the hard drive. linux is great.
I am glad I all that first, also the Grub2 boot menu will give you options to boot Windows and grub2 editor can adjust all that.
When installing Win 11 from power on I can hold down the ESC key and the next menu choose boot from USB F:

In the future I might want to access a remote desktop with low latency and call that a DIY server.
My thinking is that more compute power will help and and simulation circuits better organised, CPU is not as burdened.
Old hard disk with Windows 10 and all the applications working would be handy if not messed with. That is my take on what
cost effective upgrade in 2025 is. A Clean install but a future remote desktop does not have to be that fast as long as it works.
Think about re-purposing another decent but older computer that you turn on when needing those once in a while applications
this will free up Win 11 for eveyday get er done quick stuff.
