3. Make Acrobat Reader to reopen all documents previously opened before

   Because I have to work many times on a multitude of opened pdf files that I need to keep open for days in a row, I think a feature to restore previous session of opened documents (just like Firefox or Google Chrome) would be really helpful!

   Need Info  ·  AdminAyush Jain (Lead Software Engineer, Adobe) responded

   Hi,

   Thanks for reaching out to us for you conerns.

   We already have it implemented in Reader.
   Do “File” → “Reopen PDFs from last session.” And that should restore all the pdfs that were present in you last session at the time of Quiting the application.

   Hope this helps.

   Thanks
   Ayush Jain

6. Stop seizing control of default apps on my computer.

   I have a legal copy of Acrobat Pro X (Creative Suite) that I love (I use it over Creative Cloud supplied by my employer). PROBLEM: I cannot have Reader DC (needed for shared forms sent to me occasionally) installed at the same time as it always acts as default app even though the Windows 10 default app still lists Acrobat Pro. This is as infuriating as when Edge automatically changes this every time there is a Windows update. I already own Finereader 15 that does everything Acrobat does and more and does not require a monthly subscription. You lost a customer when you made your business model change, but stop trying to control my computer.

7. The font changes automatically by filling in the forms and using Polish diacritics

   Reporting a new bug:

   Steps to reproduce the issue:

   -> Open the document / form
   -> Use the "Fill & Sign" tool
   -> Enter any text using Polish diacritics, e.g. Ą, ą, Ć, ć, Ś, ś, Ż, ż, Ź, ź etc.

   Environment:

   -> OS: Windows 10 Pro 1909 (18363.719)
   -> Adobe Acrobar Reader DC Version: Polish (20.006.20034)

   Expected result:

   -> Forms should have a continuous homogeneous formatting. Unfortunately, even different fonts appear in one and the same field. Surprisingly, this problem does not concern German diacritics.

   Observed result:

   -> When filling out the forms, we should ensure that the text is properly formatted. Unfortunately, when using Polish diacritics, the font changes automatically and there is no possibility to maintain the formatting continuity. This makes the document look unprofessional.

8. Read Out Loud Function - highlight words or phrases as it is reading

   The Read Out Loud function really needs to be updated so that it works better for individuals with reading difficulties, such as dyslexia. If they want this aspect of adobe to work well and actually benefit many of those who need it, it should highlight words and phrases as it is reading so that is easier to follow when reading, and know where in the text the reader is.

   This will make the product a lot more accessible to people with dyslexia, dyspraxia or the likes.

9. Bug Report: Printing lines via printers configured via IPP protocol are to thin

   Bug Report: Printing lines via printers configured via IPP protocol are to thin

   We have configured new printers via the IPP protocol as notice lines on a technical drawing are printed way to thin. Also small text is barely readible.
   "Printing as image" improves it quite a bit. Opening a PDF in Microsoft Edge resolves the issue as well. Seems the Microsoft Edge render engine is way better in supporting IPP.
   As a test we have configured a printer via TCP which also resolves the issue. However Microsoft is pushing more and more to use IPP for printing. I hope this bug can be resolved asap.

10. Latin OCR in Acrobat Reader

    I often use the OCR feature on Acrobat Reader. Many of the texts I work with are in Latin. You have a long list of languages that can be OCR'd, but Latin isn't included--yet. Would love to see it added.

11. Adobe Acrobat Reader 2026.001.21529 32 bit update endlessly loops to the same version on Windows 7

    I understand Windows 7 is no longer supported by Microsoft since 2020, and 32 bit version of Acrobat Reader is no longer supported since 2023, nevertheless I see this version for DC base (32 bit) has been released on the 1st May of 2026, so what gives? I see in this version that after I've updated to it, if I were to check for Updates, I keep getting the same version as the one installed as an update!

12. What Is the Hardest Part of Writing a University Assignment?

    University assignments can be challenging for different reasons. Some students struggle with understanding the question, while others find research, planning, referencing, or academic writing more difficult. I’d be interested to hear what part of an assignment you find the most challenging and how you usually deal with it. Do you prefer using online resources, discussing ideas with classmates, or getting assignment writing help (https://www.assignmenthelper.ie) when you need extra guidance?

13. Acrobat Reader crashes when opening printer properties for RISO ORPHIS FT5230

    Adobe Acrobat Reader crashes consistently when I open the printer properties for a RISO ORPHIS FT5230 printer.

    Steps to reproduce:

    1. Open any PDF file in Adobe Acrobat Reader.
    2. Open the Print dialog.
    3. Select RISO ORPHIS FT5230.
    4. Click the printer “Properties” button.
    5. After several seconds, Acrobat Reader terminates without displaying the printer properties.

    Environment:

    • Adobe Acrobat version: 26.1.21771.0
    • Operating system: Windows 11 64-bit
    • Printer: RISO ORPHIS FT5230
    • Computer environment: Windows domain-joined PC
    • Faulting application: Acrobat.exe

    Windows Error Reporting information:

    • Event name: BEX64
    • Exception code: 0xc0000409
    • Failure module: unknown
    • Stack hash: StackHash_49ca
    • Additional value: P9 = 000000000000000a
    • Report ID: 10d95908-8955-4364-b2a4-209df3a94f74

    Comparison tests:

    • The printer properties open normally from Microsoft Word.
    • The printer properties open normally from Windows Settings.
    • The crash occurs specifically when opening the printer properties from Acrobat Reader.

    Expected result:

    The RISO ORPHIS FT5230 printer properties dialog should open normally.

    Observed result:

    Acrobat Reader terminates several seconds after the Properties button is clicked.

    The issue is consistently reproducible. A Windows Error Reporting crash dump is available if Adobe requires it.

16. Send PDF as attachment using Outlook new

    Speaking for Acrobat Reader DC for Windows, it needs to be able to email a PDF as an attachment using Outlook new. It can already email a PDF as an attachment using Outlook classic, but Microsoft is pushing customers to move to Outlook new. I get that Outlook new does not support MAPI like Outlook classic does, but these two large companies have the resources to solve this. Not every PDF workflow is suitable to be shared using a link in an email - an attachment is sometimes best.

18. Document Property / Title is filled with spaces then the PCL job name property is set with this wrong value.

    Acrobat allows the Document Properties → Title field to be filled with empty spaces. This causes the job name passed to the driver to be incorrect: the job name consists only of whitespace, which is not a valid value.

    Could this property forbid such values?

    Please check the attached picture.

19. Bug Report: Acrobat Reader installer disables inheritance and overwrites ACL on .pdf\PersistentHandler, removing required Windows capability

    Bug Report: Acrobat Reader installer disables inheritance and overwrites ACL on .pdf\PersistentHandler, removing required Windows capability SID → Windows 11 PDF full-text indexing breaks
    Product / Component

    Adobe Acrobat Reader (latest version as of Jan 2026)
    Installer / Update / Repair actions affecting Windows Search integration and registry ACLs

    OS / Environment

    Windows 11 Pro (x64)

    Windows Search indexing enabled and functioning correctly for other formats (e.g., .docx)

    PDFs are text/OCR-enabled (text can be selected and copied)

    Issue is reproducible on system A; system B (Windows 11, no prior Adobe install) indexes the same PDFs correctly

    Summary

    Installing (or repairing/updating) Adobe Acrobat Reader on Windows 11 Pro breaks Windows Explorer / Windows Search full-text indexing of PDF contents.

    The failure is caused not only by registry value mappings, but by Acrobat modifying registry key permissions (security descriptor):

    Acrobat disables permission inheritance on:

    HKLM\SOFTWARE\Classes.pdf\PersistentHandler

    Acrobat overwrites the ACL (DACL) to include only classic principals like:

    SYSTEM, Administrators, Everyone

    This process removes Windows default capability SID ACEs (notably a capability SID in the form S-1-15-3-…)

    Windows Search’s SearchFilterHost.exe runs with that capability SID in its token (verified in Process Explorer as Group with flag “Capability”).

    Once that SID is no longer granted ReadKey on the PersistentHandler registry key, SearchFilterHost.exe receives ACCESS DENIED and the PDF IFilter chain cannot be resolved/loaded.

    Result: PDFs appear in the index (metadata indexed), but System.Search.Contents remains empty, and Explorer cannot find text inside PDFs.

    Re-enabling inheritance (or restoring default ACL) immediately restores PDF full-text indexing.

    Impact / Severity

    High. Acrobat Reader installation can silently disable OS functionality:

    Explorer / Start Menu search cannot find PDF content

    Windows Search indexes PDF metadata only, not contents

    Users may incorrectly assume PDF content indexing is broken or unreliable in Windows 11

    Affects enterprise setups and forensic/search workflows heavily

    Expected Behavior

    After installing Acrobat Reader:

    Windows Search / Explorer should continue to index PDF contents using the Windows built-in PDF filter (Windows.Data.Pdf.dll) or a compatible handler chain.

    Acrobat should not modify registry key ACLs in a way that removes Windows-required capability SIDs.

    PDF full-text search should continue working the same way as before installation.

    Actual Behavior

    After Acrobat Reader installation:

    PDF contents are no longer searchable (while .docx continues working)

    In the Windows Search index:

    PDF file entries exist

    System.Search.Contents is empty (no extracted text)

    Process Monitor shows registry access failures:

    SearchFilterHost.exe → RegOpenKey / RegQueryValue on .pdf\PersistentHandler results in ACCESS DENIED

    Windows.Data.Pdf.dll is not loaded during PDF indexing attempts until permissions are fixed

    Reproduction Steps (100% reproducible)
    Baseline (works)

    Ensure Windows Search is enabled, and the folder containing PDFs is indexed.

    Confirm that a given PDF has selectable/copyable text (OCR or embedded).

    Confirm PDF full-text search works:

    Explorer search finds terms inside PDF content

    In Windows Search index, System.Search.Contents contains extracted text (or at least non-empty)

    Confirm handler chain is present:

    HKCR.pdf\PersistentHandler default value is {1AA9BF05-9A97-48C1-BA28-D9DCE795E93C}

    HKLM\SOFTWARE\Classes\CLSID{1AA9BF05-…}\PersistentAddinsRegistered{89BCB740-6119-101A-BCB7-00DD010655AF} points to:
    {6C337B26-3E38-4F98-813B-FBA18BAB64F5}

    {6C337B26-…}\InprocServer32 points to %SystemRoot%\System32\Windows.Data.Pdf.dll

    Trigger (break indexing)

    Install Adobe Acrobat Reader (latest version).

    After install, check registry ACL of:

    HKLM\SOFTWARE\Classes.pdf\PersistentHandler

    Observe:

    Inheritance disabled

    DACL replaced/flattened with entries like:

    SYSTEM

    Administrators

    Everyone

    Missing capability SID entries (notably S-1-15-3-1024-… capability SID)

    Observe failure

    Copy a PDF into an indexed folder (or modify a PDF to trigger indexing).

    Confirm:

    Indexing occurs for metadata (System.ItemPathDisplay present in index)

    But System.Search.Contents empty

    Explorer cannot find content terms in the PDF

    Evidence / Diagnostics
    1) Registry key ACL change causes failure

    User experiment:

    When permissions on .pdf\PersistentHandler are set to inherit from parent .pdf, PDF content indexing works.

    When inheritance is disabled and the capability SID ACE is removed, PDF indexing fails.

    Adding back the capability SID (explicit allow ReadKey) or re-enabling inheritance restores indexing.

    Minimal permission requirements observed:

    SYSTEM + capability SID (S-1-15-3-…) required

    Removing Users/Admins/CreatorOwner does not break indexing

    Removing SYSTEM or the capability SID breaks indexing

    2) Process token includes the capability SID (confirmed)

    Using Process Explorer:

    SearchFilterHost.exe → Properties → Security → Groups

    The capability SID appears in Groups with Flag = “Capability”.

    This demonstrates that Windows Search components rely on capability SIDs in access checks.

    3) ProcMon shows access denied

    In Process Monitor during PDF indexing attempt after Acrobat installation:

    SearchFilterHost.exe

    Registry open/query on .pdf\PersistentHandler yields ACCESS DENIED

    Stack shows impersonation-related frames (e.g., kernel path mentions dereferencing impersonation token)

    After fixing ACL inheritance, access succeeds and:

    Windows.Data.Pdf.dll becomes visible/loaded in the indexing chain

    PDF full-text indexing works again

    4) Why SYSTEM alone is insufficient

    Even when DACL includes SYSTEM FullControl, access can still fail due to Windows token restrictions / capability gating:

    Access may require both:

    standard SID authorization AND

    capability / restricted SID set authorization

    This matches observed behavior: SYSTEM alone does not restore indexing if capability SID ACE is missing.

    Root Cause

    The Acrobat Reader installer (or update/repair routine):

    modifies security descriptors (ACLs) of the registry key HKLM\SOFTWARE\Classes.pdf\PersistentHandler

    disables inheritance

    rewrites DACL to contain only classic principals (SYSTEM/Admin/Everyone)

    thereby removing default Windows capability SIDs such as S-1-15-3-1024-…

    Windows Search indexing host (SearchFilterHost.exe) includes that SID with flag “Capability” and requires ReadKey

    result: SearchFilterHost cannot read PersistentHandler → cannot resolve filter chain → cannot extract contents

    This is a permissions regression introduced by Acrobat install behavior.

    Workaround / Fix
    Immediate workaround (manual)

    Restore default Windows ACL by re-enabling inheritance:

    regedit

    Navigate to: HKLM\SOFTWARE\Classes.pdf\PersistentHandler

    Permissions → Advanced

    Enable inheritance

    Apply

    PDF full-text indexing resumes immediately after next indexing cycle.

    Alternative workaround

    If inheritance must remain disabled:

    Add explicit allow ReadKey ACE for:

    Capability SID: S-1-15-3-1024-1065365936-1281604716-3511738428-1654721687-432734479-3232135806-4053264122-3456934681

    Ensure SYSTEM also retains ReadKey

    Recommendation to Adobe Engineering

    Do not modify security descriptors for .pdf\PersistentHandler unless absolutely necessary.

    If ACL changes must be made:

    preserve inherited ACEs (do not disable inheritance)

    do not remove “unknown” SIDs (capability SIDs)

    If Acrobat registers its own handler chain, it should do so by updating values, not rewriting registry permissions.

    Add a regression test:

    install Acrobat on clean Windows 11

    ensure PDF System.Search.Contents extraction still works under Windows Search

    verify capability SIDs remain present in ACLs

    Additional Notes

    On a second Windows 11 system (no prior Adobe install), PDF full-text indexing works correctly with the same PDF files.

    The issue is independent of PDF content (OCR/text selection works; document is new and created from Word).

    Microsoft documentation indicates capability SIDs are legitimate and commonly used; they should not be removed from ACLs.

    Bug Report: Acrobat Reader installer disables inheritance and overwrites ACL on .pdf\PersistentHandler, removing required Windows capability SID → Windows 11 PDF full-text indexing breaks
    Product / Component

    Adobe Acrobat Reader (latest version as of Jan 2026)
    Installer / Update / Repair actions affecting Windows Search integration and registry ACLs

    OS / Environment

    Windows 11 Pro (x64)

    Windows Search indexing enabled and functioning correctly for other formats (e.g., .docx)

    PDFs are text/OCR-enabled (text can be selected and copied)

    Issue is reproducible on system A; system B (Windows 11, no prior Adobe install) indexes the same PDFs correctly

20. Suggestion: Custom UI Themes inspired by Geometry Dash aesthetics

    Hi,
    I think the current Acrobat UI is a bit too "corporate." It would be amazing if Adobe allowed users to apply custom themes or skins.
    As a fan of Geometry Dash, I’d love to see a vibrant, neon-style "Dark Mode" similar to the game's aesthetic. Even small icons that react to user interaction (like the icons in GD) would make the PDF reading experience much more engaging for younger users.
    Just a thought to modernize the software!
