Accentuation gets doubled inputted " ΄΄ "

Question

As you can see the accentuation gets double input.
I have checked for keylogger virus found nothing.

I have switched languages from english to greek and reverse, nothing.

deleted greek as language, restarted, redownloaded packs, nothing

changed system language to english exited, nothing

checked drivers via device manager, deleted-restarted, nothing

unchecked all third party and microsoft services via msfconfig (or whatever it is)-restarted, nothing

tried a different keyboard, nothing

the weird thing is that i only get it outside the windows. it works on Settings, works on Search. anything outside of windows stuff its broken.

Hi,

Thank you for sharing your question. I understand how frustrating it is to see accent marks being doubled, especially after trying so many troubleshooting steps already. Issues like this can be disruptive when typing in Greek, and it makes sense that you want a clear explanation and a reliable fix.

Based on my knowledge, doubled accent input often points to software interference rather than keyboard hardware. Users with Greek, Portuguese, and other international layouts have experienced the same behavior, and it commonly appears after updates, input‑method corruption, or background processes altering keyboard behavior.

In many cases, this issue is caused by processes or software that modify keyboard input. Performing a clean boot, resetting the keyboard layout, checking for third‑party input tools, or running a system file check has helped users restore normal accent behavior. Some cases were resolved by disabling or removing background applications that interfered with the input system, while others were fixed by repairing the language pack or reinstalling the affected layout.

To move toward a resolution, you can try resetting the Greek keyboard layout again and verifying that no background utilities, accessibility tools, or third‑party input managers are active. Running sfc /scannow to repair input‑related system files has also been effective in restoring expected accent behavior. If the issue persists even on multiple keyboards and appears briefly after rebooting as in other reported Greek‑layout cases it may indicate a startup process causing the conflict.

May I ask whether the problem also occurs in the on‑screen keyboard and whether you’ve recently installed or updated any security tools, keyboard customization utilities, or language‑related apps? With a bit more detail, I can guide you step‑by‑step to isolate the process causing the double‑accent behavior and help restore your Greek accent key to normal. I’m here to continue helping you until the issue is fully resolved.
