Windows 10: If I change my windows 11 to another operating system, can I change it back ?

I bought a Laptop with pre-installed windows 11. I want to change to Linux for my work. I will need Linux only for a few months. But If I want to get back to my original windows 11, may I? I already know my product key. If I again install windows 11, with my Microsoft account, will there be any issue ? As I am going to change my OS for the first time ever I am scared.

operating system language problem

I have upgraded my windows 8.1 to windows 10 in August 2015. Since then I am struggling to change the operating system language but not able to do it as I cannot understand Dutch in which the system got upgraded. I bought this lenovo laptop from Netherlands,
so it has default operating system language as dutch. I tried many tips suggested online to change it but not able to change it. Please suggest how can I get rid of these problem. I want to have administrative language as English. Please suggest step by step
procedure. It is even difficult to figure out which is pc setting option, recovery option or update option in dutch.

Thank you.

 

Windows 8.1 update changed the language, can't change back

Maybe, these will help... it seems it is a common enough problem.

Language packs are no longer available after you upgrade to Windows 8.1

And, sort of the same here --> Add a language or keyboard

Quote from above MS web page:

Spoiler Download and install language packs
You'll need to download the language pack if you want to make a language your Windows display language (that's the language you see most often in Windows and apps).

• Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings.
  (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, click Settings, and then click Change PC settings.)
• Tap or click Time and language, and then tap or click Region and language.
• Tap or click a language that says Language pack available underneath, and then tap or click Options.
• Tap or click Download. The download process might take a while, depending on your PC and the size of the language pack.
  If you want to make this your display language, see the next section "Change your Windows display language".

Change your Windows display language
To change your Windows display language (that's the language you see most often in Windows and apps), first add a language, download and install the language pack, and then follow these steps.

• Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings.
  (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, click Settings, and then click Change PC settings.)
• Tap or click Time and language, and then tap or click Region and language.
• Tap or click the language that you want to set as your display language.
• Tap or click Set as primary to move the language to the top of the list. If the language can become your Windows display language, you'll see Will be display language after next sign-in appear under the language.
• Sign out and then sign back in to finish.

Default Programs / Change Operating System

Hello,

Windows keeps changing my default programs automatically without my permission and installing things I don't want. I know how to change my default programs, I am just tired of having to do it since Windows keeps changing them. I am looking to install an
alternative operating system. What are the best steps to do this as I am unfamiliar and I could not find it anywhere on your site? I enjoy some Microsoft products but I am tired of Windows changing things without my permission.

I am not here to ask about other products just want to make sure I don't break my computer if I change operating systems. I looked on your website to see if I could find information about changing however I could not find it.
